Chemical Name: BPC-157 (Body Protection Compound-157) a synthetic pentadecapeptide Molecular Formula: CHNO Molecular Weight: ~1,419.5 g/mol CAS Number: 137525-51-0 Amino Acid Sequence: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly Leu-Val Classification: Synthetic research peptide (pentadecapeptide) for laboratory investigation only Purity: 98 %99 % (HPLC-verified research grade) Appearance: White to off-white lyophilized (freeze-dried) powder Intended Use: Research use only
What makes BPC-157 distinctive among research peptides is a combination of three properties rarely found together: it has no sequence homology to any other known peptide, it is completely stable in human gastric acid for at least 24 hours (unlike most growth factors and peptide analogues, which are rapidly degraded), and it remains active across an exceptionally broad effective dose range from nanogram to microgram per kilogram bodyweight in pre-clinical models without any known toxic dose having been established in animal studies to date
