The test list for two peptides in one vial, line by line, and which lines are commonly missing

Published 26 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
A complete certificate for the blend answers for each component what a single-peptide certificate answers for one: identity by mass — two calculated and two observed values — and purity by HPLC with the method stated, with related substances assigned to each. It adds a line no single-peptide certificate has: the composition ratio of the two main peaks, corrected for their different responses, confirming the 1:1 formulation. Water and counterion content are measured for the cake; net peptide content is stated per component or for the whole, and the certificate should say which. A certificate with one mass and one purity for a two-component product has described half of it.

Identity and purity, twice

Observed mass of BPC-157 against about 1,419 daltons and observed mass of the fragment against its calculated value, each with the charge state used. Main-peak purity for each from the same chromatogram, with impurities assigned by mass. The method and wavelength stated once for both.

The two-peaks page describes how a single run yields two figures.

The blend-specific lines

Composition ratio, which confirms the formulation and is the line most often absent. Water by Karl Fischer for the cake. Counterion total and, where apportioned, per component. Net peptide content with its basis stated. Endotoxin where measured, since the blend may be destined for cell work. Sterility is not expected and should not be implied.

The counterion and net-content page sets out the apportionment.

Why it is here

Because a blend certificate is read differently from a single-compound one and a reader should know what to look for. The catalogue batch documentation states which tests were performed. It describes documentation and no use of the pack.

The BPC-157 + TB500 blend is supplied by REVIVE LAB UAE for laboratory research use only, with identity by mass spectrometry and purity by HPLC for each component of the batch. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
