Evidence summary
Why PeakForm Peptides is rated 8/10
Our conclusion
PeakForm has one of the broadest public COA databases in this batch. Current sampled reports support identity, purity, measured content, and lot linkage. Some newer reports also include endotoxin results.
Independent reputation evidence is still limited, and historical records contain material failures. Match the current lot and do not treat a purity percentage as proof of label content.
Verification notes
What we reviewed, with the limits of that evidence kept explicit.
COA review
The COA database contained 76 records and clearly labeled records as current or historical. PeptidePrices opened current BPC-157 10mg lot PP-3548854-P, 5-Amino-1MQ 50mg lot PF-2026-098-2, and Tesamorelin 20mg lot PF-2026-043-2. The reports confirmed identity, listed 99.24% to 99.82% purity, and measured 10.5mg, 48.48mg, and 22.84mg.
Reputation & rating context
The newer Freedom reports included two endotoxin replicate passes. The library also preserves weaker historical evidence. AOD-9604 lot PF-2026-020 reported 91.222% purity. TB-500 lot PF-2026-018 reported 99.075% purity but only 5.66mg for a 10mg product. These records are historical or current as labeled on PeakForm's page and must be matched to the received lot.
Evidence note
PeakForm links to a Google rating, but a mature exact-domain independent review count was not established during this review. Strong laboratory transparency and good operating policies support an 8/10 score, with reputation and company transparency holding the score below the top tier. Affiliate status does not affect the score.
