BPC-157: a UK research buying checklist
A BPC-157 listing should answer the questions your laboratory needs resolved before approving a purchase. Use this checklist to turn a product name into a precise material requirement.
Define the material, not just the label.
Ask the supplier for the exact identity, chemical form, relevant modifications and specification. Record what your study requires and ask for clarification when the listing does not establish it. A familiar compound name is not a substitute for your laboratory’s specification.
Clarify what “5mg” means.
Treat the pack quantity as a declared nominal quantity until its basis is clear. Ask whether the figure describes net peptide content or another material basis, and what analytical or manufacturing records support it. A purity percentage and a quantity are different parts of the specification.
Connect the evidence to the lot.
Check the original report’s sample identity, batch identifier, date, laboratory and test method. Ask how the tested sample relates to the lot that would be dispatched. A report for a different lot does not answer that connection.
Compare the delivered offer.
Request the actual unit price, applicable tax, minimum quantity, delivery charge, availability and lead time. Keep the agreed documents and discrepancy process with the quote. A lower headline price is useful only when the material and terms meet the requirement.
A procurement guide, not evidence of Portman stock or testing. Confirm the actual offer and original records before purchasing. For laboratory research only.
