Testing records
LL-37 COAs
A COA shows the batch it names, not the lot shipped today. Vendors post certificates for specific batches; none of them shows which lot a vendor ships now, and a missing COA is shown as missing.
20 tracked offers for LL-37 from 19 vendors: 13 have a public COA for the exact product and strength, 5 of them confirmed at the lab; 7 do not. The newest test date on file is Jul 26, 2026. Labs named: Bio Analytical Laboratory, Inc., BioRegen, Bioviridian, Chromate, Freedom Diagnostics, ILS Laboratories and 5 more.
By product and vendor
Each row is one vendor's offer for one exact product. It shows the report behind the testing state: for a lab-verified product the newest report the lab confirmed, otherwise the newest report on file. A lab link appears only where the lab confirmed the report. Every archived report is stored with its SHA-256 hash.

What each testing state means
- Lab-verified COA (5): the lab's own portal or lookup confirms the report.
- Product COA on file (8): a public COA names this product and strength; it is not confirmed at the lab.
- COA for another strength (1): the vendor's COA is for this compound at a different strength.
- Vendor tests other products (6): the vendor publishes COAs, none matched to this product.
Picks need a COA for the exact product and strength tested within 12 months; see the methodology.
