BPC-157 is a stable synthetic pentadecapeptide (15 amino acids, MW 1,419.55 Da) and one of the most popular research peptides — which unfortunately also makes it one of the most counterfeited. Verified purity and identity are the main sourcing concern.
What to Look for When Sourcing BPC-157
Require a third-party COA (HPLC and mass spectrometry) confirming ≥98% purity and the 1,419.55 Da molecular weight. Because BPC-157 is high-volume and frequently faked, buy only from vendors with verifiable US-based manufacturing and full batch documentation.
Typical Price Range
Research-grade BPC-157 typically costs about $20–$35 per 5 mg vial. Its popularity drives competitive pricing, but suspiciously cheap vials are a common vector for underdosed or impure material.
Storage and Handling
BPC-157 is unusually stable — lyophilized powder tolerates ambient shipping and stores well at 2–8°C. Reconstituted peptide should be refrigerated and used within the vendor's stated window.
Red Flags to Avoid
No COA or an unaccredited lab, prices far below market, vague sourcing, and any human-use or FDA-approval claims. Given how often BPC-157 is counterfeited, third-party identity verification is essential.
