Simple Peptide is one of the better-documented vendors we've checked, but we couldn't read its prices. As of October 19, 2026, it lists Delray Beach, Florida, names Freedom Diagnostics on lot-matched COAs and has 47 independent tests on Finnrick. We couldn't read a product list or prices, so this page has no price table.
Notice: Simple Peptide's products are sold for in-vitro laboratory research only. They are not FDA-approved and not for human or animal use. This review covers supplier transparency and prices only. We didn't buy or test any products. Some vendors pay us a commission when you buy through our links. That never changes a score or a price ranking.
