Description
Listed as a laboratory reference material, BPC-157 is a synthetic pentadecapeptide, freeze dried and sealed under vacuum. Fill weights of 5 mg and 10 mg are offered here, chosen before you order. The cake is white to off-white. Not for human or veterinary consumption, and neither a food nor a drug.
The label on BPC-157 carries the compound, the fill weight and the lot number, and that is the extent of it.

Lyophilized powder, and the price per milligram of BPC-157
The vial contains lyophilized powder. Water was taken out of the frozen solution under vacuum, which is gentler on a peptide than any form of heat and leaves behind a solid with very low moisture. That dryness is the whole point of the format. It is also why the certificate reports a water figure, since any moisture that stayed in the cake is moisture available to hydrolyse the peptide over time. Nothing about BPC-157 is sold by volume.
How the per milligram figure is worked out
Milligram content is the unit BPC-157 is sold in, because it is the only figure that makes two listings comparable. This listing has more than one strength, so the arithmetic has to be done per option: take the price of the option and divide it by its milligram content. The result is printed under each price. It is the number that makes two vial sizes, and two vendors, comparable at all. Compare BPC-157 on that basis rather than on the price of the glass. The case is made at greater length in why price per milligram beats the price on the bottle.
What the certificate of analysis reports
Read the certificate from the top and check the identifiers before the numbers. Lot number first, matched against the vial. Date of analysis next, because an old date on a new lot is a sign the document has been recycled. Then purity, then the mass spectrometry comparison, then water content, then the signature and the name of the laboratory. A sheet missing the lot number is not a certificate, it is a leaflet. The certificate issued with BPC-157 is specific to the lot and not to the product line.
Assays are run by an outside contract laboratory rather than in house. Independence of that kind matters, and it has a limit: the figure still depends on the sample that was submitted, which is why lot by lot testing rather than periodic testing is the part that matters. Stock is withdrawn from sale where the certificate for BPC-157 does not support the figures here. See how to read a certificate of analysis and why we publish the batch that failed.
Purity, identity and moisture are three different measurements
Water content is measured by Karl Fischer titration and reported as a percentage by weight. The figure matters twice. Residual water is water available to hydrolyse the peptide over the life of the vial, and it is also mass sitting on the balance, so a high moisture figure quietly eats into how much peptide a stated fill weight contains. The same methods are run on this material as on every other lot on this shelf, and formulae and expected masses for compounds of this class can be checked through the NCBI chemistry and literature databases.
Why the name is inconsistent, and how to store the vial
Expect the same compound under several names. Transliteration adds variant spellings on top of that, which is why sequence and measured mass, not the title of a listing, are the identifiers that hold. BPC-157 appears only in its abbreviated form on this site. The words behind the three letters read as a claim about what the compound does, so they are not written out in the title, the web address, the image description or the text. The catalogue name carried by this vial is the one the trade uses, and a trade name is not an identifier.
Sealed, cold, dark and dry. Short term storage at refrigerator temperature and long term storage at minus 20 degrees Celsius or colder are the standard conditions for lyophilized peptide material of this kind. Keep the certificate with the vial, since the lot number is the only thing joining the two.
What this listing refuses to say
Supplied for in vitro and laboratory research by qualified purchasers. It is not a drug, not a dietary supplement, not a cosmetic and not approved for human or animal use. No dosing figure, administration route, timing, injection site or reconstitution procedure appears on this page, and none will be supplied on request. Those omissions are deliberate rather than accidental. No part of this page describes a use for this material in a person or an animal. Bacteriostatic water, sterile diluents and syringes are stocked separately rather than sold as a set with the vial.
Two things are true at once. This is sold as a laboratory reference material, and that sentence on its own settles nothing, because a page that describes effects, timing or quantities for a person is describing a use whatever the footer says. See research use only is not a legal strategy.
The certificate for the lot in stock is linked above, including where a lot did not pass its own stated figures. There is nothing else to read into this listing beyond the figures on it. This item sits on the repair and recovery shelf, inside the research peptide catalogue, and every certificate we hold is on the lab results page.
