A peptide certificate of analysis worked example
This worked example reads the published PDF for BPC-157 batch GQ700822, issued on August 3, 2026. Its 99.71% HPLC purity and 10.69 mg net peptide content are separate reported results for that sample. They are not specifications for another batch or evidence of suitability for human use.
Read the identification fields first
Read results with their method
Do not multiply the label by the purity
The label amount, the peak-area percentage and net content answer different questions. Multiplying 10 mg by 99.71% does not reproduce or replace the separate quantitation. The PDF also includes conformity rows and summary statistics: those should be read as reported, without assuming repeated labels represent independent samples.
Verify the document, then resolve differences
The GQ700822 certificate page links to both the PDF and the laboratory portal. Compare identifiers and results across them. A verification link confirms the record presented by that service; it does not by itself establish manufacturing origin, delivery history or clinical suitability. If versions disagree, ask the laboratory which is applicable before relying on the affected figures.
Apply the method to your own batch
Open the matching lot page, record the source and date, compare the product and sample, and read the reported methods. An unlisted test is not a pass. This example does not mean a current order contains GQ700822, and none of its measurements should be transferred to another lot.
