At fifteen residues BPC-157 is short and inexpensive to synthesise, which changes what is worth checking. Outright substitution makes little economic sense — sequence fidelity and net content do.

Order this testA pentadecapeptide with the sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. Proline-rich sequences like this one are where solid-phase synthesis most often drops or duplicates a residue.
Mass spectrometry confirms all fifteen residues and catches the deletion and insertion products that proline-rich sequences generate during synthesis. A missing residue shifts the mass by a known amount, which is exactly the kind of thing weighing the molecule reveals and timing it does not.
This is where BPC-157 buyers are most often surprised. Material sold under different salt descriptions can carry meaningfully different net peptide content for the same stated milligram figure.
A 5 mg vial of a TFA salt at full purity holds roughly 4 mg of actual peptide. Nothing has gone wrong — that is simply what the salt weighs.
94.2–115.1%
was the interquartile range of measured amount for BPC-157 — one of the three widest spreads in the dataset. Median amount was 103.50% of label. 3.5% of samples did not contain the stated peptide at all.
Mendias C, Awan T, 2026 — 6,441 grey-market samples across 14 compounds and 203 synthesis companies. Posted as a preprint; not peer reviewed. The dataset is self-selected third-party testing, so buyers who already suspected a problem are over-represented. Full findings and caveats.
One unopened vial. Detailed posting instructions arrive with your order confirmation, immediately after you pay.
No. Lyophilised peptides travel safely at room temperature, which is how nearly all samples reach us.
An independent Ontario laboratory. Every certificate we issue names the facility that ran it — we are a testing service, not a laboratory, and we would rather say so than let you find out from the report.
You get the result. We do not soften findings, and we do not charge differently depending on what the analysis shows.
Yes. Every certificate carries an identifier that anyone can check against our records, including the vendor you bought from.
