Description
The BPC-157 and TB-500 blend is supplied as two peptides co-lyophilized in one vial, a pentadecapeptide and a fragment of thymosin beta-4, freeze dried and sealed. The vial holds 10 mg in total, made up of 5 mg of BPC-157 and 5 mg of TB-500. The cake is white to off-white. Every figure quoted on this page comes from the certificate issued against the lot number on the vial. For laboratory research use, and not for human or veterinary consumption.
The milligrams of each component are stated separately rather than added into one number, because a blend total tells you nothing about the split. The label on the BPC-157 and TB-500 blend carries the compound, the fill weight and the lot number, and that is the extent of it.

Why it is a powder, and what a milligram of the BPC-157 and TB-500 blend costs
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 the BPC-157 and TB-500 blend is sold by volume.
How the per milligram figure is worked out
Milligram content is the unit the BPC-157 and TB-500 blend is sold in, because it is the only figure that makes two listings comparable. Run the division and the result is about $12.72 per milligram. Purity belongs in that calculation too, at least loosely, since a lot assaying lower is delivering fewer milligrams of the target sequence for the same money. The certificate figure is on the page, so the adjustment is available. Compare the BPC-157 and TB-500 blend 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.
The certificate of analysis for the BPC-157 and TB-500 blend
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 the BPC-157 and TB-500 blend is specific to the lot and not to the product line.
The laboratory that runs the assay has no ownership connection to this company. That arrangement is not a seal of approval and it does not make the figures infallible, but it does remove the obvious conflict of interest in a vendor grading its own stock. Stock is withdrawn from sale where the certificate for the BPC-157 and TB-500 blend does not support the figures here. See how to read a certificate of analysis and check the lab before you check the numbers.
What the methods actually measure
The purity line on the certificate is an HPLC result. Chromatography separates whatever is in the vial into peaks, and the percentage is the main peak measured against all of them. Impurities in a synthetic peptide are mostly shortened versions of the intended sequence, plus traces of the reagents used to build it. They show as small peaks beside the large one, and they are part of the arithmetic. The same methods are run on the BPC-157 and TB-500 blend 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.
Names, abbreviations and how to keep the BPC-157 and TB-500 blend
Abbreviations here are inherited rather than designed. They come from the groups that first made a compound, from ingredient registers, from development programmes and from vendors, so two listings can look different and be identical. Several abbreviations on this shelf unpack into descriptions of activity. They are not unpacked here, and where a compound cannot be described without that, only its measurable properties are described. The catalogue name carried by this vial is the one the trade uses, and a trade name is not an identifier.
Handling notes are short. Sealed, dry, cold and dark, at 2 to 8 degrees Celsius for the short term and minus 20 degrees Celsius or below for anything longer. The stability window for the lot is printed on this listing. Keep the certificate with the vial, since the lot number is the only thing joining the two.
Research use only: this vial is a reagent
Sold to qualified purchasers for laboratory research only. Not for human or veterinary use. The page carries no dosing information, no protocol, no administration instructions and no account of physiological activity, because publishing any of those would be describing a use this material is not sold for. We will not supply them privately either. 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.
The limits of that sentence need stating. A research use only line describes what is sold, it is not a shield, and the enforcement record shows whole product pages being read rather than disclaimers alone. See research use only is not a legal strategy.
Lots that failed their own stated figures are kept rather than deleted, which is the point of an archive as against a highlight reel. 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.
