A BPC-157 / TB-500 research blend supplied as a single lyophilized vial, referenced in tissue-repair research models. Component ratios are printed on the lot COA. For laboratory research.
Released by the lot, never the batch average. A batch average hides the outliers — we publish the number for the lot you actually receive, matched to the code printed on your vial.
Match the lot number on your vial to its record, then open the report and read it yourself.
View certificates of analysis
If a lot doesn’t match the certificate published for it, we replace it. Send us the lot number on your vial.
Broken or compromised vials are replaced. Photograph the parcel as it arrived and file a claim from your account.
Tracked shipping on every order. If a parcel is lost or marked delivered but never arrived, file a delivery claim and we’ll make it right.
Build & save
Mix and match three different compounds and the extra 5% comes off automatically at checkout. Free shipping still kicks in at $199.

Lyophilized reference materials supplied strictly for in-vitro and laboratory research. They are not drugs, supplements, or medical products, and nothing on this site describes human or veterinary use.
Yes. Batches are analysed by an independent laboratory. The lot number printed on your vial matches a certificate of analysis published on our COA index, so you can verify the exact material you received.
Store lyophilized vials at −20 °C, protected from light. For research reconstitution, bacteriostatic water is the standard diluent; keep the reconstituted solution refrigerated at 2–8 °C.
Orders placed before the daily cutoff ship same or next business day, cold-packed and discreetly packaged from the Central Valley. Tracking is emailed on dispatch.
It means these compounds are sold for laboratory and analytical work only. They are not for human or animal consumption, diagnosis, or treatment, and you must be 21 or older and a qualified researcher to order.
If a lot doesn’t match its certificate, or a parcel arrives damaged, is lost, or is marked delivered but never arrives, file a delivery claim from your account and we’ll replace or refund it.
