How do I reconstitute BPC-157?

Concentration equals vial size divided by the bacteriostatic water added, and units on a U-100 syringe equal draw volume in millilitres times 100. Common vial sizes for BPC-157 are 10, 20 mg.

BPC-157 protocol

BPC-157 (Body Protection Compound 157). The published work on this compound is animal or cell-culture research. No human dosing schedule exists to cite.

How BPC-157 works

A synthetic pentadecapeptide derived from a sequence found in human gastric juice. Rodent work reports accelerated tendon, muscle and gut healing, with effects on angiogenesis and nitric-oxide signalling proposed as mechanisms.

BPC-157 dosing — what the literature actually supports

Animal data only. This is the single most important thing to know about BPC-157: despite how widely it is discussed, there are no published human clinical trials establishing a dose. The entire evidence base is rodent work, where amounts are given in micrograms per kilogram of rat and administered by routes that do not map onto human use. Any human schedule you see quoted — including the widely circulated microgram-per-kilogram figures — is an extrapolation somebody performed, not a measured human amount from a trial.

We publish a schedule when there is a citable human source and we say so when there is not. Filling this space with a number nobody measured would make the page look more complete and be worth less than nothing to you.

Reconstitution and measurement

This part is arithmetic and does not depend on the evidence level. Concentration is vial size divided by the bacteriostatic water you add. Draw volume is your target amount divided by that concentration. Units are draw volume times 100, because a U-100 syringe reads 100 units per millilitre. Common vials for BPC-157: 10, 20 mg.

Storage and stability

Dry powder

Cold, dark and dry. Lyophilized peptide is the stable form — keep it that way until you intend to use it.

After reconstitution

Refrigerate at 2–8 °C, protect from light, and plan around a limited window. Do not freeze a reconstituted vial — freeze-thaw damages peptides.

Mixing

Run bacteriostatic water down the inside wall of the vial rather than onto the powder, then swirl. Never shake.

Inspect before use

A clear solution is expected. Cloudiness or particles mean discard, not use.

Reported effects

No human safety data from controlled trials.
Rodent studies consistently report a wide therapeutic window with little observed toxicity, which is not the same as human safety.
In 2022 BPC-157 was added to prohibited-substance monitoring in sport, which is worth knowing if you are tested.

Sourcing BPC-157

Whatever you are working with, the documentation matters more than the price. Ask for a batch certificate of analysis whose lot number matches the vial you actually receive — a COA for a different batch tells you nothing about yours.
