BPC-157 reconstitution calculator
The arithmetic below is the same for any compound. What changes is the vial in front of you, so read its label and enter those numbers rather than numbers from anywhere else.
Worth knowing before you calculate anything. BPC-157 rates ★★☆☆☆ on our evidence scale, and its safety profile is poorly characterised. Extensive rodent data across many tissue types; human efficacy trials minimal and none for the musculoskeletal claims it is sold for.
A calculator will return a tidy number for any compound you give it. That number says nothing about whether the compound works, whether the dose is sensible, or whether the product in the vial is what the label claims.
Where the dose figure should come from
This page does not supply one. For BPC-157 the honest position is set by the evidence: Extensive rodent data across many tissue types; human efficacy trials minimal and none for the musculoskeletal claims it is sold for.
The book reports dose figures in four labelled bands, so you can always see whether a number comes from an approved label, from a published trial, from what circulates without trial support, or from nothing at all. That labelling matters more than the number.
If you have a certificate of analysis
Check whether it reports a net peptide content lower than the labelled weight. Peptides are usually supplied as a salt and hold water, so a vial labelled 5 mg can contain less than 5 mg of the peptide itself. Where that figure is given, it is the one to enter above.
The certificate describes what is in the vial. The evidence rating at the top of this page describes whether BPC-157 has been shown to work in humans. Neither answers the other's question.How to read a certificate of analysis.
What this page will not do
It will not tell you what to take or whether to take it, and it is not medical advice. Sterile technique, storage and the provenance of the vial matter as much as the arithmetic. What is actually known about storage.
About BPC-157
BPC-157 is a synthetic chain of 15 amino acids, based on a sequence identified in human gastric juice. The name stands for "Body Protection Compound". It has been studied for more than three decades, mostly in animal models of injury and gut health. It is not approved as a medicine in any country yet, and human trials remain limited. Supply today is mainly through research-chemical suppliers and compounding clinics.
