COA & lab verification
PeakForm publishes 76 current and historical records from Freedom Diagnostics and Horizon Analytical. 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 LC-MS or UPLC-MS identity, listed 99.24% to 99.82% purity, and measured 10.5mg, 48.48mg, and 22.84mg respectively. The two sampled July Freedom reports also included endotoxin passes. The library transparently retains historical exceptions, including a 91.222% AOD-9604 record and a TB-500 10mg report that measured 5.66mg. Match the exact current lot and strength. Affiliate status does not influence the rating.
Our verdict on PeakForm Peptides
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.
More about PeakForm Peptides
PeakForm Peptides is a US research supplier based in Scottsdale, Arizona. Its live WooCommerce catalog contained 39 products on July 31, 2026. The site publishes research-use, return, affiliate, and laboratory-record pages.
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.
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.
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.
