Pentadecapeptide BPC-157, laboratory term
Research-use notice: This article summarizes published scientific literature for educational purposes. It is not medical advice and does not provide dosing, administration or human-use information.

Pentadecapeptide means a 15-residue peptide. On this site the name points at BPC-157, the synthetic sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, abbreviated GEPPPGKPADDAGLV, with a free-peptide mass near 1419 daltons. It is a partial sequence from a gastric protein. For the structure note, see What is BPC-157?. The shop URL is BPC-157 10 mg. This glossary entry is neither the listing nor a protocol.
A common name is not an identity test. Compare the observed mass on the 10 mg certificate anchor with the calculated mass. Blend fills that also contain a thymosin beta-4 fragment are different SKUs. Their PDFs do not document the single-peptide 10 mg vial. TB-500 is not a pentadecapeptide.
Frequently asked questions
- Does the BPC-157 10 mg certificate cover the TB-500 blend?
- No. The 5 mg/5 mg and 10 mg/10 mg blends are separate lots. The public library anchors a report on the 5 mg/5 mg blend that does not document the 10 mg pentadecapeptide.
- What does research use only mean for this sequence?
- The lyophilized solid is sold for laboratory work. The label is not a Health Canada drug authorization and this page does not provide personal-use steps.
