TB-500 Peptide Dosage Calculator

Computes the reconstituted concentration, the draw volume, and the corresponding mark on a U-100 syringe scale.

Reading the scale: the highlighted mark corresponds to the calculated volume on a standard U-100 insulin syringe — 100 units = 1 mL, and each numbered tick is one unit.

Reconstituting TB-500 Peptide

TB-500 and BPC-157 both come as 10 mg vials, so their mass arithmetic is identical — and their molar arithmetic is not. TB-500’s molecular weight is 4963.44 against BPC-157’s 1419.55, a factor of roughly 3.5. Reconstituted to the same mg/mL, a TB-500 solution contains about a third as many molecules per millilitre. For work that compares the two or runs them in parallel, that gap is why mass per millilitre and molarity are not interchangeable units, and why both are reported when the molecular weight is available.
