Overview
BPC-157 at a glance
The name stands for body protection compound. Most of the published research on BPC-157 comes from a small number of laboratories using rodent models, including studies of tendon, gut and wound tissues; both reviews and critical narrative reviews exist.
Because the literature is concentrated, independent analytical confirmation of any batch is the main source of confidence for researchers.
Structure
The sequence is GEPPPGKPADDAGLV with a free N-terminus and a free C-terminal acid. Three proline residues in a row make the N-terminal half rigid. The calculated formula matches PubChem exactly.

Expected values
Mass spectrometry reference
Ions calculated from the monoisotopic mass 1418.7042 Da. Use them to check an LC-MS result; for larger peptides the instrument usually reports a deconvoluted mass close to 1419.5 Da instead.

Analytical notes for batch documents
- BPC-157 is supplied in several salt forms, including acetate and arginine salts; the salt form changes the molecular weight on the COA.
- Vesta also lists research blends of BPC-157 with TB-500 at several strengths.
- No residue in this sequence is especially prone to oxidation or deamidation, so most extra peaks are likely to be synthesis-related impurities or adducts.
- The molecular weight of a vial of powder includes counter-ions and water; the share of the powder that is peptide is the net peptide content.

Questions
Frequently asked questions
What is BPC-157?
BPC-157 is a synthetic pentadecapeptide (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) that corresponds to a partial sequence of a protein found in human gastric juice.
What is the molecular weight of BPC-157?
BPC-157 has the formula C62H98N16O22, an average molecular weight of 1419.54 g/mol and a monoisotopic mass of 1418.7042 Da. A salt form, a different counter-ion or a metal complex changes the molecular weight printed on a certificate of analysis, so compare like with like.
How can I check the identity of a batch of BPC-157?
Compare the intact mass measured by LC-MS with the expected values on this page, for example [M+2H]2+ at m/z 710.3594. Confirm that one main HPLC peak carries that mass and that the batch code on the report matches the vial. The guides on mass spectrometry and on certificates of analysis explain each step.
Which BPC-157 products does Vesta list?
Vesta lists 9 products for BPC-157: 5 mg, 10 mg, 20 mg per vial in kits of 10 vials, plus 6 research blends that contain it. Prices are shown per kit in US dollars, and shipping is paid by the customer.
