cGMP, heavy metals & COA
Payarmin Quality Standards
Supplement makers must follow cGMP under 21 CFR 111, but test results are voluntary to publish. Payarmin publishes no certificate of analysis, no heavy-metal results and no third-party seal. Here is what that means and how to ask for your lot's records.
Clinical takeaways
- U.S. law (21 CFR 111) requires dietary supplement makers to follow current good manufacturing practice.
- Publishing a certificate of analysis, heavy-metal results or third-party seals is voluntary, and Payarmin publishes none.
- The label names a distributor, not the manufacturing facility.
- You can ask for your lot's certificate of analysis; a reputable maker can provide it.
The three-tier verification standard, applied honestly
A strong quality story has three layers: a facility that follows cGMP, independent lab testing of each lot for identity, potency and contaminants, and public documents that let a buyer confirm both. Here is where Payarmin stands on each.
| Tier | What it means | Payarmin status |
|---|---|---|
| 1. cGMP manufacturing | Facility follows 21 CFR 111: written procedures, identity testing of ingredients, batch records | Required by law; facility not named, no audit published |
| 2. Third-party assays | An ISO/IEC 17025 lab tests the lot for potency, microbes and heavy metals | No results published |
| 3. Public records | Certificate of analysis or seal (USP, NSF) you can check | None found as of October 16, 2026 |
What cGMP actually guarantees
The cGMP rule requires a maker to establish specifications for identity, purity, strength and composition, and to test or verify that each batch meets them.[1] It does not require the maker to publish results, and FDA does not approve supplements before sale.[2] So "made in a cGMP facility" is the legal floor, not a mark of distinction, and on its own it tells you nothing about this product's lots.
What a certificate of analysis should show
- Product name, lot number and test date matching your bottle
- Identity tests for key botanicals (HPTLC or similar)
- Assay results for any itemized amount, here chromium
- Microbial limits: total plate count, yeast and mould, E. coli, Salmonella
- Heavy metals: lead, arsenic, cadmium, mercury, against stated limits
- The lab's name and accreditation
Heavy metals deserve attention in any botanical blend, because plants take them up from soil. USP chapter 2232 sets daily exposure limits for elemental contaminants in supplements. Green tea extracts in particular have a documented, rare liver-injury signal that USP reviewed in 2020.[3][4]
How to request your lot's records
Email [email protected] with your lot number and ask for the certificate of analysis and the name of the testing lab. Save the reply. If none arrives within the refund window, that silence is information you can use when deciding whether to keep the product.
