7Stax Lab Results: Where to Find Each Batch COA and How to Read It

7Stax lab results are posted as Certificates of Analysis (COAs) in the 7Stax Lab Reports portal, grouped by product strength. Each product page links to the reports for its strength. To use a COA, match its batch or lot number to the one on your pack.

Our guide on how to read a Certificate of Analysis walks through every section. This page covers where the reports live, what they show, and how independent testing fits in.

Status as of October 12, 2026: MGPI, MGM-15 and MGM-16 are Schedule I (91 FR 54948, effective August 26, 2026). 7-OH is not federally scheduled; DEA issued new notices of intent on October 9, 2026 using updated HHS thresholds. 7Stax products are for adults 21 and over where legal.

Where to Find 7Stax Lab Results

There are two routes to the reports. Every product page carries a link reading "Click here to view the lab reports," which opens the COAs for that strength. The "Lab Reports" link in the main menu opens the same portal, hosted on lingoapp.com, with folders by strength.

Product line	Lab report folders in the portal
Premium 7-OH Kratom Alkaloid Tablets	20mg, 30mg, 50mg, 80mg, 100mg and 150mg Tablet COAs
Nano Tech Mitragynine Tablets	40mg, 80mg and 120mg MIT Tablet COAs
7OH Shot	50mg Shot COAs

The portal loads its files in the browser, so allow a moment for documents to appear. If a folder looks empty or you cannot find your batch, contact 7Stax through its contact page with the lot number.

What a COA Reports

A COA is a lab report for one batch. It names the laboratory, the sample and its batch or lot number, the test methods, the results with units and limits, and the date and signature. Read beside the label, it shows whether the label figure matches what the lab measured.

• Laboratory details: name, address and any ISO/IEC 17025 accreditation number, the international standard for testing laboratory competence.
• Sample details: brand, product, format and batch or lot number.
• Method: usually HPLC or UPLC for alkaloids.
• Results: each analyte with units, limits and a pass or fail where applicable.
• Sensitivity: limit of detection (LOD) and limit of quantification (LOQ).
• Sign-off: analysis date, issue date and signature.

Our guide to reading a 7-OH tablet package label covers the label side of that comparison.

Alkaloid Results: 7-OH and Mitragynine

The alkaloid section is where the label figure is checked. For Premium tablets and the shot, look for 7-hydroxymitragynine. For Nano Tech tablets, look for mitragynine, which is the labeled alkaloid on that line. Results are usually given in milligrams per gram, milligrams per unit, or as a percentage.

Check the unit before comparing. A result in mg per gram must be multiplied by the unit weight to get mg per tablet. Values below the LOQ appear as "less than LOQ" or "ND" (not detected) rather than as a number.

A COA lists only what the lab was asked to test. If MGPI, MGM-15 or MGM-16 are not on the panel, the report says nothing about them. Our post on the DEA's August 2026 order lists the names to look for.

Heavy Metals and Microbial Screens

A full COA screens for four heavy metals, lead, cadmium, mercury and arsenic, reported in parts per million or billion against a limit. A microbial screen checks for yeast and mold, total aerobic count, E. coli, Salmonella and Staphylococcus aureus. Residual solvent results may also appear.

Each line should show a result, a limit and a pass or fail. If a section is missing, the report does not cover it.

How to Match a COA to Your Batch Number

• Find the batch or lot number printed on your pack.
• Open the portal folder for your product's strength.
• Find the report with the same batch or lot number and product name.
• Check that the flavor and format on the report match your pack.
• Note the analysis date. A report should belong to the batch you hold.

If no report matches your number, ask 7Stax before relying on any other batch's results. Terms on the label such as "Nano Tech" are explained in our glossary of common formulation terms on 7-OH product labels.

Test My Kratom and 7Stax Lab Results

Test My Kratom is a third-party publication that tests kratom alkaloid products and posts results online. It has published several 7Stax test posts between October 2025 and May 2026. Its reports compare a single sample with the label claim, so results apply to the batch it tested.

Its posts reported measured 7-OH both above and below label figures. Posts from February and March 2026 reported MGM-15 in some 7Stax tablet samples, before MGM-15 became Schedule I. Its May 6, 2026 post on two 80mg tablets did not report MGM-15.

Third-party results are a cross-check, not a replacement for the batch COA. Compare dates and batches before drawing conclusions.

Frequently Asked Questions

Does 7Stax post a COA for every batch?

7Stax posts COAs by strength in its Lab Reports portal and links them from every product page. If your batch number is not listed, contact 7Stax with the lot number before relying on another batch's report.

What does "ND" mean on a COA?

ND means not detected: the compound was below the method's limit of detection. It does not prove the compound is absent, only that any amount was below what the test could find.

How recent should a COA be?

A COA should belong to the batch you hold, whatever its date. A report more than twelve months old for a product still being sold is generally treated as stale.
