What's in the tablet: 7-OH, pseudoindoxyl and MGM-15 labels against the lab

A 7-OH tablet's card states a number of milligrams. Behind it, sometimes, sits a laboratory report. This site has now written dossiers on a dozen of the brands and shops that sold these tablets, and in most of them there is at least one report that can be set beside the card: a certificate the brand paid for, a test a buyer-funded tester paid for, or a forensic laboratory's test purchase. This article puts every one of those results in one place, adds what the federal government and two state agencies have published from their own testing, and asks the plain question. How much of what the label says was in the tablet?

The subject here is what laboratories measured in products, as the laboratories reported it. Nothing in this article says what any amount does to a person. This site carries no dose guidance for 7-OH, pseudoindoxyl or kratom, and none is implied by a number in a table.

Figure 1. The record in order, drawn by us from the documents cited below. The tests came first. The federal numbers followed them by months. [1]

Three kinds of report

The reports in this article come from three kinds of submitter, and the difference matters more than the laboratory's name.

An independent tester. TestMyKratom buys products at retail, sends them to a laboratory and posts the certificates. Most of its reports for these brands are from Anresco Laboratories in San Francisco; some are from Cora Science in Austin.[2][3] It is paid by its readers' purchases: it asks them to “please consider purchasing your products through the links on our website” because “this is our only source of income”.[4] Its Dozo page says the same thing another way, “buying from our affiliate links helps us fund more tests”.[5] In February 2026 it added a second interest, in the post that carried its Limitless results: “we are selling our own tabs now”.[6] It is the only regular buyer-side tester of most of these brands, and its reports are laboratory certificates with its own name as the customer.

The brand. A brand, or a company acting for it, sends a sample to a laboratory and posts the certificate, usually behind a QR code on the card. PharmLabs San Diego is the laboratory on the certificates of Dozo Perks, Proxie, Kanna21 and Script Botanicals.[7][8][9][10] Every PharmLabs certificate carries the same two sentences. One: “PharmLabs relies on information provided by the client regarding the identity, sampling, and chain of custody of the submitted material”. The other: “Results apply only to the specific sample(s) and batch(es) identified on this COA and do not represent any other lot, batch, or product from the client”.[11] A brand certificate is a true statement about a sample the brand chose.

A forensic laboratory. The Center for Forensic Science Research and Education (CFSRE), in Pennsylvania, buys products in shops through its federally funded NPS Discovery programme and publishes what it finds next to what the pack advertised.[12] Its May 2026 report on 7-OH products opens with a warning about its own field: “testing for these two alkaloids is extremely limited”.[12] Two state agencies, in Utah and Tennessee, have published what their testing found in products sold as cat's claw.[13][14]

Figure 2. Who sent the sample, and which laboratory tested it. A report submitted by a brand describes the sample the brand chose to send. Drawn by us from the reports cited in this article. [4]

How much of the label was there

Forty tests in the dossiers compare a measured amount with a labelled one. The chart puts each on one scale: the measured amount of the alkaloid the card names, as a percentage of the card's figure. Where a card gives one number for 7-OH and pseudoindoxyl together, the chart uses the two together.

Figure 3. Forty tests, one mark each. The independent tests sit mostly to the left of the line; the brands' own certificates from 2025 on sit mostly on or to the right of it. Every point is listed with its source in the table below. [15]

The pattern follows the submitter. TestMyKratom's 24 results run from 3 to 110 per cent of the label; 22 of the 24 are under it, and the middle of them is about 72 per cent. The brands' own 11 certificates run from 56 to 121 per cent, and their middle value is 102 per cent. CFSRE's five comparable rows run from 76 to 109 per cent, with a middle of 88. These are different products bought at different times, so the chart does not show that any one brand's certificates are wrong. It shows where the independent testing stops. For none of the brand certificates from 2025 or 2026 in the chart did the dossiers find an independent test of the same product to set beside it.

Opia is the one brand tested by both sides of the market. TestMyKratom's first certificate, in October 2024, found 12.75 mg of 7-OH in a Mintopia tablet sold as 20 mg, and noted that “this result of this sample is confirmed with a retest”.[2] Its weakest Opia result was a liquid shot: “Opia Classic 7-OH + Pseudo Liquid Shot contained 12.31mg of combined 7-hydroxy and pseudo, which was about 59% weaker than its 30mg claim”.[15] CFSRE bought the Wild Berry card in 2026 and found 13.7 mg of 7-OH and 1.4 mg of pseudoindoxyl, 15.1 mg together against 20 on the card.[12] TestMyKratom's figure for the same product was 15.50 mg.[15] A forensic laboratory and an affiliate tester, buying separately, landed within half a milligram of each other. That is the best check on the tester's method anywhere in these dossiers. Our Opia dossier has the rest.

Figure 4. The forensic laboratory's own label-against-result table, May 2026. The Opia row is the only one in it that is also in this site's dossiers. [12]

Figure 5. The first independent certificate for an Opia tablet, October 2024: 12.75 mg of 7-OH in a tablet sold as 20 mg, and methanol at 2,790 ppm under a 3,000 ppm limit. [2]

Opia's two mitragynine tablets are left out of the chart because their claim is disputed. TestMyKratom graded them against 150 mg and found 51.54 and 67.77 mg; a reader read the card differently: “it says 37.5mg mitragynia speciosa and 25mg of mitragynine per tab”, a quarter tablet.[16] On either reading the tablets held less mitragynine than the card. Opia's own certificate, for a card sold as 120 mg Pseudo, found 26.85 mg of pseudoindoxyl, 98.56 mg of mitragynine and 156.63 mg of alkaloids in all, in a tablet weighing 750 mg.[35] The name on that card matches the total, not the alkaloid in the name.

Dozo Perks shows what changes when the submitter changes. In 2024 both sides agreed the tablets were short. TestMyKratom's five tests of the 20 mg tablets ran from 36 to 78 per cent of the label.[5] The brand's own certificates that year agreed in direction: 76 per cent for a Chill Berry two-pack in July, 56 per cent for a Wild Mango six-pack in October, on certificates whose client was “tested for latro inc”.[17][7] From May 2025 the brand's certificates show 92, 116 and 109 per cent.[18][19][20] We found no independent test of a 2025 or 2026 Dozo product to set beside them. One reader's complaint about the later certificates was their tidiness, “impossibly consistent results like 100mg tabs being exactly 100mg”.[36] The certificates themselves are PharmLabs', for samples the client sent; nothing in them shows a result altered. The Dozo dossier reads each one.

Figure 6. A community tester's results for Dozo Perks, five tests of the 20 mg tablets in 2024, from 36 to 78 per cent of the label. [5]

Figure 7. The brand's own certificate for the same 20 mg tablet in a six-pack, October 2024: 67.00 mg of 7-OH in a pack labelled 120 mg. In 2024 the brand's laboratory and the independent tester agreed in direction. [7]

Proxie is a brand whose certificates come from the same laboratory, and in one case from the same intake, as Dozo's. PharmLabs received Proxie's single-tablet samples on 2025-05-12 as “sample id sd250513 032 113739”,[26] and the Dozo Perks tablet two places before it as “sample id sd250513 028 113735 tested for dozo perks”.[37] The brand says “every batch is third party lab tested at pharmlabs san diego iso iec 17025”.[8] Its four cited certificates run from 86 to 106 per cent of the label.[25][26][27][28] The March 2025 certificate was issued twice, with a “Laboratory Note: COA Update 5/1/25 Sample Name, Photo and Tested For updated as per client request”.[25] The certificate does not say what the first name was. Proxie has its own dossier.

Figure 8. A brand certificate issued twice. The second issue, of 1 May 2025, renamed the sample and the client at the client's request. The result is 86 per cent of the label. [25]

Kanna21, the supplier behind several tablet brands, has one certificate in the record: 30.57 mg of 7-OH in a sample named 30 mg tablets, printed also as 55.59 mg per gram.[9] No Kanna21 label was found to compare it with, so the 102 per cent in the chart is against the sample's name. Pseudoindoxyl was not on the panel. The Kanna21 dossier explains whose site it was posted on.

Figure 9. A supplier's certificate, May 2025: 30.57 mg of 7-OH in a tablet sampled as 30 mg, printed as 55.59 mg per gram. Pseudoindoxyl was not on the panel. [9]

7 Kings, an Ohio shop, is the only seller here whose own results sit well above its labels. Its Sweet Mint tablet, sold as 60 mg, tested at 72.37 mg of 7-OH on an SC Labs certificate of September 2026, and the shop listed it as “60mg sweet mint 7 oh tested 74 1mg”.[29][38] Its certificates describe very small batches: the MGM-15 powder's reads “batch size 2 units sample size 2 units”, a batch of two grams that was the whole sample.[39] A certificate like that describes the bag that was tested and no other. A buyer's own test of a 60 mg tablet, at a laboratory the post does not name, reported 58 mg of 7-OH and 4 mg of pseudoindoxyl.[40] The 7 Kings dossier covers the shop.

Figure 10. The one brand certificate in this article well above its label: a tablet sold as 60 mg, tested at 72.4 mg of 7-OH. [29]

The strips. Five brands' 7-OH strips were tested in 2024, one strip each, for our dossier on Pain Relief Kratom, the Thai wholesaler buyers traced several of them to. Three came in between 20 and 23.3 mg; Hyzen's was 16.34 mg against 24 claimed, and Sub7ohmz's 6.8 mg against 20.[30][31][32][33][34] One strip per brand is a sample of one.

Figure 11. One of five strip tests from 2024, all one strip per brand: 23.3 mg of 7-OH in a strip sold as 25 mg. [32]

Modus has one independent test: capsules from batch 2024-08 at 6.79 mg against 10.[24] Of the brand's own QR-linked certificates for its 100 mg tablet, a buyer wrote that “they have coas from san diego pharmacy showing 93 mg a tab”; we could not read that certificate.[41] The Modus dossier has the rest.

What the label did not name

The worse problem is not a short tablet. It is a tablet with something else in it.

Limitless Remix. TestMyKratom bought a Limitless Remix tablet as “30mg Cherry psuedo”, a pseudoindoxyl product; the card's front named no compound.[23] Anresco found 0.80 mg of pseudoindoxyl, no 7-OH, and MGM-15. The tester's summary: “it also contains 6.92mg of unadvertised mgm-15”.[21] The same report failed the tablet on a residual solvent, chloroform, at 226 ppm against a limit of 60, with the note “chloroform failure confirmed with dilution”.[23]

Figure 12. The worst label match in this article, February 2026. A tablet bought as 30 mg of pseudoindoxyl held 0.80 mg of it and 6.92 mg of MGM-15, which the label did not name, and failed on chloroform. [23]

Limitless Platinum. A month later, in March 2026, Anresco reported MGM-15 in all three Platinum flavours TestMyKratom bought, at 4.15, 5.71 and 4.85 mg a tablet, beside 84 to 89 mg of 7-OH.[21] The tester failed them on that alone, and said what would have passed them: “we would be willing to give this product a passing grade if it were transparent with its contents”.[21] A second laboratory disagreed about the MGM-15, which is the next section. The Limitless dossier has both.

CFSRE's test purchases. The forensic laboratory's 7-OH table has three products with pseudoindoxyl the pack did not advertise. The largest is a liquid, EDP Buzzz: 25 mg of mitragynine advertised a bottle, more than 150 mg found, and 36.7 mg of pseudoindoxyl.[12] The eat Ohmz Red tablet and the edp 7Oh tablet each held a fraction of a milligram to 1.4 mg.[12] Its MGM-15 report found the compound in two products that did not name it: an 8 Wonder bottle advertised as a proprietary blend, and a 7 Stax Mitragynine card advertised as “80 mg, Nano Tech Mitragynine”.[42] CFSRE's note on the pattern: “similar to the trajectory of other smoke shop products, kratom alkaloids now appear under the guise of” proprietary-blend labelling.[42]

Figure 13. CFSRE's MGM-15 test purchases, May 2026. A card sold as 80 mg of nano tech mitragynine contained dihydro-7-hydroxy mitragynine as well as mitragynine. [42]

State findings. Utah's agriculture department and poison control centre said on 2026-07-30 that tablets sold as cat's claw in Utah shops had been tested: “The tested products contained both mitragynine pseudoindoxyl and MGM-15, which are opioid-acting compounds derived from the kratom plant”.[13] Tennessee's Bureau of Investigation warned in September of cat's claw products containing MGM-15 and said that “mislabeled products can make it difficult for buyers and retailers to know what they are purchasing or selling”.[14] Our deep dive on what replaced 7-OH follows the cat's claw products.

Claims nobody has posted a certificate for. Not every report of an unnamed compound comes with the report. Of Dozo's MG-X tablets, sold as mitragynine, one buyer wrote that “on the pack it says they have 125 mg of mit” but “i did look up the coa and it says they contain more mgm 15 than anything”.[43] Another wrote that “no coa was available for the old mg x”.[36] Our Dozo dossier could not find the certificate they describe. The brand's certificate for its Kratom Extracts tablets, of February 2026, has an MGM-15 row that reads not detected.[44] Script Botanicals, a cat's claw tablet, publishes PharmLabs certificates that read MGM-15 not detected, “MGM-15 (MGM) 0.186 0.562 ND ND”, on samples “Tested for Cali Extrax”.[10] A campaigner's test, relayed on Reddit, “came back that it had 19.6 mg of emgeem in each dose”; a reader noted the campaigner was “trying to get seven banned”.[45] No laboratory, lot or certificate for that test has been published. The brand's earliest certificates, from Encore Labs in February 2026, did not test for MGM-15 at all, and marked the alkaloids they did test as “beyond scope of accreditation”.[46] Its results table prints a potency pass for each row, “SD260619-075 Script Botanicals Paradise Blend 250mg Berry Blitz Jun 23, 2026 Pass 250mg” among them; the certificates behind the rows report alkaloids not detected and no potency result.[47][10] The Script Botanicals dossier sets the two side by side.

Figure 14. A brand's results table that prints a potency pass for each row. The certificates it links report kratom alkaloids not detected and contain no potency result. [47]

Opia is the counter-example. A buyer asking about MGM-15 in Opia tablets in April 2026 was told that “tmk has no reported any mgm 15 being laced in to it without disclosure so far”,[48] and when Opia did sell MGM-15, in its NanoAlkaloids card of July 2026, the facts panel named it as dihydro-7-hydroxymitragynine.[49]

Figure 15. The opposite case, July 2026: a label that does name MGM-15, as dihydro-7-hydroxymitragynine, under 2 per cent, seven weeks before the federal order. [49]

What else was in the tablet: solvents

A tablet made from an extract can carry the solvent the extract was made with. Four of the dossiers have a number for one.

Product	Solvent	Result	Limit printed	Report
Opia Mintopia, lot 2024-09	methanol	2,790 ppm	3,000 ppm	Anresco for TestMyKratom[2]
Limitless Remix, lot 2026-02	chloroform	226 ppm	60 ppm	Anresco for TestMyKratom[23]
7 Kings 80% powder	methylene chloride	40	600 (a buyer's reading)	ICAL, for the shop[50]
7 Kings 86% MGM-15 powder	methylene chloride	not detected	1 µg/g	ICAL, for the shop[39]
StoutAlkz 97% MGM-15 powder	methanol	not detected	3,000 ppm	an unnamed report the seller linked[51]

Opia's Mintopia tablet passed, at 93 per cent of the limit Anresco applies.[2] Limitless Remix failed, at nearly four times its limit.[23] The 7 Kings pair is a lesson in limits. A buyer compared two solvent reports from the same laboratory and found methylene chloride limited at 1 on one and at 600 on the other: “on the 80 powder the limit says 600 with a result of 40”. The shop answered that “ical gave inconsistent specifications”.[50] Both numbers exist in published standards: 600 ppm is the international residual-solvent guideline for medicines,[52] and 1 µg/g is the figure the same laboratory printed on the shop's MGM-15 certificate, “methylene chloride 1 g g nd”.[39] A result of 40 is well under the first and forty times the second.

StoutAlkz, a Florida powder seller, linked a report that lists “methanol 3000 ppm not detected” and names no laboratory, client or batch.[51] A rival seller later circulated a methanol result for some of its MGM-15 batches, described in one post as “something along the lines of 62 000 methanol when 75 was the acceptable limit”.[53] A buyer added the context: “the 3rd party who tested it was bx and they were going thru a dispute”.[54] We found neither side's report, so neither number was checked. The StoutAlkz dossier has the dispute.

Two laboratories, one lot

Limitless Platinum, lot 2026-03. TestMyKratom sent tablets from the same lot to two accredited laboratories. Anresco found 83.66 to 88.92 mg of 7-OH and 4 to 6 mg of MGM-15 in each flavour.[21] Cora Science found 69.90 to 71.70 mg of 7-OH,[21] and on the one certificate it published in full, for Blue Razz, “dihydro-7-hydroxymitragynine report results <loq mg/unit”, below what it could quantify.[3] The documents do not say whether both laboratories received tablets from the same bottles. What both agree on is that the 100 mg tablet held 70 to 89 per cent of its label.

Figure 16. Two accredited laboratories, one lot, both paid by the same tester. They differ by 13 to 17 mg of 7-OH a tablet and on whether MGM-15 is there at all. [3]

Figure 17. The second laboratory's certificate for the Platinum Blue Razz: 69.9 mg of 7-OH. Its MGM-15 line, on the next page, reads below the limit of quantitation. [3]

Some of that gap may be chemistry rather than error. The Association of Public Health Laboratories told its members in June 2026 that “7-OH and MP are isomers requiring testing to differentiate”, that “adding base to 7-OH may result in the formation of MP”, and that “adding acid to MG may result in the formation of 7-OH”.[55] CFSRE's MGM-15 report says the same of the newer compound: “laboratories must be aware that kratom alkaloids, including dihydro-7-hydroxy mitragynine, present complex analytical challenges including isomers, interconversion and instability”.[42] A laboratory that prepares a sample with acid can report 7-OH that was mitragynine in the tablet. One that never bought an MGM-15 reference standard cannot report MGM-15. CFSRE's own monograph says MGM-15 “was first identified by our laboratory in September 2025 and confirmed after acquiring standard reference material”.[56] The certificates in this article do not say how each sample was prepared.

Figure 18. The public health laboratories' bulletin, June 2026. Its right-hand column is the reason two honest laboratories can report different alkaloids from the same tablet. [55]

StoutAlkz's 99 per cent. A buyer posted the seller's MGM-15 certificate in March 2026: Altitude Consulting of Englewood, Colorado, 99.393 per cent, with the sample received, extracted and analysed on the same day.[53] A rival seller then said it had sent the same material to Cora Science and got about half that.[53] That second result was described, not posted.

Figure 19. A seller's MGM-15 certificate, posted by a buyer in March 2026: 99.393 per cent. A rival seller said a second laboratory found about half that. [53]

Wonderland Gardens' arithmetic. The vendor's certificates come from Wonderland Labs, of Vista, California, whose own accreditation page says “we have a pending iso iec 17025 accreditation via perry johnson laboratory accreditation”.[57] On its pseudoindoxyl certificate of October 2024, linked from a listing that named two batches, the rows do not convert from micrograms per millilitre to per cent by the same factor: pseudoindoxyl at 44.0 is printed as 44.0 per cent, 7-OH at 79.9 as 7.9 per cent.[58][59] The laboratory's own site warns that “from time to time a few bad apples choose to digitally edit certificates of analysis from a lab”, and offers to check any certificate.[60] We have not asked it to. The Wonderland Gardens dossier sets out all four certificates.

Figure 20. A vendor's laboratory certificate whose rows do not convert from micrograms per mL to percent by one factor, October 2024. Our Wonderland Gardens dossier sets out the arithmetic. [58]

Counterfeits and swapped pills

A certificate describes what a laboratory received. It says nothing about the card on a shop counter, and in these dossiers the counter is where buyers say things went wrong. Every report below is a buyer's account. None was followed by a laboratory test that a buyer posted.

Other pills in sealed bottles. Seven buyers between February and September 2026 said a Limitless bottle held something other than Limitless tablets: antacids, ibuprofen that “had advil printed on them”, and laxatives.[61][62][63] The September report says “the bottle i opened had been sealed, with the cotton still in it”.[63] Who swapped them the posts do not establish. The Limitless dossier lists all seven.

Figure 21. What one buyer says came out of a sealed Limitless Platinum bottle in September 2026: laxative tablets. No test of the bottle's contents was posted. [63]

Different tablets in the right card. Two buyers of Modus Smax in early 2026 described flat tablets without the brand's stamp, where “the pills are normally rounded with really nice embossed m on them”.[41][64] Opia buyers described cards with the right packaging and tablets without the Opia name pressed into them.[65] Opia's verification codes are printed on the shop's display box, and its verification page says: “if you are a consumer and would like to verify your product please visit your opia retailer for authentication”.[66]

A certificate for a different product. A Proxie buyer in September 2025 wrote that “the qr code takes me to a dozo perks coa”.[67][68] A buyer from Kures, a Las Vegas web shop, scanned a bottle and found that “when i scan the qr code it takes me to labs for the 150mg blisters”.[69] A Proxie buyer in June 2026 compared two bottles and asked whether one was a copy: “mine says distributed by ijaam wholesales and my bottle also has no website on it”.[70]

A shop accused of selling fakes. Twelve threads accuse Kures of selling counterfeits; one buyer wrote that “they sent me a counterfeit bottle of 7stax i have proof of the bottle and the tablets i have emailed”.[71] Kures' terms put the question upstream: “kures does not manufacture produce formulate process test alter relabel repackage or design any third party branded products”.[72] The Kures dossier has both sides. A test of a sealed card bought from a shop beside the same product bought from the brand would settle a case of this kind. Nobody in these dossiers has posted one.

For the frauds that are not about the tablet at all, the fake shops and the crypto-only checkouts, see the long read on 7-OH scams.

What the DEA's numbers mean for these results

The federal government's position on these compounds changed three times while these tests were being run, and each change used a different kind of number.

July 2026: a per-article threshold. The DEA's notice of intent of 2026-07-06 proposed to control 7-OH above “greater than 0.050 percentage by weight/weight, weight/volume, or volume/volume or greater than 1.00 milligram of 7-hydroxymitragynine in the article”.[73] Every 7-OH product in the chart held more than 1.00 mg of it, apart from the Limitless Remix, which held none.[23]

August 2026: no threshold. The temporary order placing mitragynine pseudoindoxyl, MGM-15 and MGM-16 in Schedule I set none: “This temporary order is effective August 26, 2026, until August 26, 2028.”[74] Its evidence came partly from a “market audit of online retailers”, and from forensic laboratories: “MGM-15 was detected as a tan solid drug that originated from New England”.[74] It dated “the emergence of MGM-15 in commercially available products was in September 2025”, and said that “the first confirmed appearance of mitragynine pseudoindoxyl in consumer products was reported in 2024”.[74] From that date a tablet like the Limitless Remix or Platinum as Anresco measured them, or any product in the CFSRE table with pseudoindoxyl in it, would contain a Schedule I substance.[21][12]

Figure 22. The order as published on 26 August 2026. It sets no threshold: any amount of the three compounds is covered. [74]

October 2026: a concentration and a ratio. On 2026-10-09 the DEA filed two notices for publication on 2026-10-14. In the first, “dea is withdrawing the july 7 2026 notice of intent related to 7 hydroxymitragynine”, and proposes to place 7-OH and pseudoindoxyl in Schedule I when either, or both together, is above a threshold.[1] The threshold has two prongs, and either is enough. One is concentration: “greater than 1 mg per gram for solid powders encapsulated material or other solid forms”. The other is a ratio: “the mass of mitragynine present divided by the mass of [7-hydroxymitragynine], or [mitragynine pseudoindoxyl], or the combined amount of [7-hydroxymitragynine] and [mitragynine pseudoindoxyl] if both present, is less than 100”.[1] Until a new order is published, “the august 26 2026 temporary order placing mitragynine pseudoindoxyl in schedule i of the csa without a threshold remains in effect until either it expires or the new temporary order is published”.[1] The notice adds that “neither hhs nor dea has made a finding that these substances are safe to use at below threshold levels”.[1] It is a notice, not an order.

Figure 23. The proposed threshold, in the notice filed on 9 October 2026 for publication on 14 October. Either prong is enough. [1]

The certificates in this article let the concentration prong be checked directly. Kanna21's certificate prints 55.59 mg of 7-OH per gram.[9] Proxie's Bars certificate is for a product named “100mg 7oh per 750mg”, and found 93.03 mg, about 124 mg a gram.[27] 7 Kings' Sweet Mint held 72.37 mg in a 0.762 g serving, about 95 mg a gram.[29] Opia's 120 mg Pseudo held 26.85 mg of pseudoindoxyl in a 750 mg tablet, about 36 mg a gram.[35] Each is 35 to 125 times the proposed line. The ratio prong is no closer: Kanna21's certificate has 0.41 mg of mitragynine to 30.57 mg of 7-OH,[9] a ratio near 0.01 where the notice draws the line at 100. None of these tablets is near either line; each is far past both.

Figure 24. Four brand certificates measured against the proposed line, by our arithmetic from the certificates and the tablet weights they or the packs give. Each is between 35 and 125 times over it. [1]

The second notice keeps MGM-15 where the August order put it: “today dea is providing notice of its intent to publish a new temporary order for mgm 15 and mgm 16 that will maintain the temporary placement of these substances in schedule i of the csa without change”.[75] So MGM-15 has no threshold at all. Any amount of it, including the 4 to 7 mg Anresco found in Limitless tablets and the not-detected that PharmLabs reports for Script Botanicals, is measured against zero. The notice's own evidence is thin on laboratory data, and says so: “mgm 15 has been detected in at least 2 drug materials”.[75] Of 7-OH products as a class, the companion notice says that “information on their purity identity quantity and safety is unknown”.[1] The forty tests above are a small part of what would fill that gap.

Figure 25. The companion notice, filed the same day: MGM-15 stays in Schedule I with no threshold. [75]

Our deep dive on the Florida and Utah rules covers the state thresholds that came first, and how they compare.

Still open

• Whether the brands' 2025 and 2026 certificates match their tablets on a shelf. No independent test of a Dozo, Proxie or Kanna21 product from those years was found in TestMyKratom's pages or in buyers' posts read for the dossiers. One sealed card of each, bought at retail and sent to a laboratory the brand did not choose, would settle it.
• Which laboratory was right about the Limitless Platinum lot. The Anresco certificates for those three tablets were not found archived; their MGM-15 figures come from the tester's brand page.[21]
• The MGM-15 certificates buyers describe and nobody has posted: Dozo's MG-X,[43] and the campaigner's test of Script Botanicals.[45]
• Whether any tablet called counterfeit was one. No buyer in these dossiers posted a test of a suspected fake.
• The published text of the two October notices. This article quotes the public-inspection copies filed on 2026-10-09; the Federal Register publishes them on 2026-10-14.[1][75]
