Mixing two peptides in one vial (for example BPC-157 + TB-500)? Enter both amounts and the water, then a target dose of the first peptide to get the units to draw and how much of the second peptide rides along.

About the peptide blend calculator

Reconstituting two peptides in the same vial, a classic example being a BPC-157 and TB-500 recovery blend, is convenient but makes the dosing math trickier because every draw delivers a fixed ratio of both compounds.

Enter each peptide's amount and the shared bacteriostatic water. The calculator finds the concentration of each, then for your target dose of the first peptide it returns the volume to draw in units and how much of the second peptide that same draw delivers.

Because the ratio is locked once you mix, choose the amounts so that a sensible dose of peptide A also gives a sensible dose of peptide B. If you only run one compound, the reconstitution calculator is simpler.

FAQ

Can I mix two peptides in one vial?

Many compatible peptides such as BPC-157 and TB-500 are commonly blended for convenience. Once mixed, every draw delivers a fixed ratio of both, which this calculator quantifies. Confirm compatibility before combining.

How is the second peptide's dose decided?

It is not independent, it is fixed by the ratio you mixed. When you draw enough volume for your target dose of peptide A, the calculator shows exactly how much peptide B comes with it.

What if I want different ratios?

Change the milligram amounts of each peptide before mixing, or the water volume. The calculator updates both concentrations and the per-dose delivery instantly.
