The toolkit

Peptide dosage calculator.

Enter your vial amount, diluent volume, and target dose to see concentration, volume per dose, and total doses — with a live syringe.

Quick presets
mg

As printed on the vial label or COA.

mL

Bacteriostatic water you add to the vial.

A calculation input from your research reference — never a suggested dose.

Calibration is the barrel's marking scale — it stays fixed no matter which barrel you pick.

A 1 mL U-100 barrel holds 100 units but is still calibrated at 100 units per mL.

About this peptide dosage calculator: enter your vial amount (mg), diluent volume, and target dose to get your reconstitution concentration in mg/mL and mcg/mL, the volume per dose in mL and syringe units (U-100, U-50, or U-40), and total doses per vial. Research calculation tool — it does not recommend doses or establish suitability for human use.

Evidence standards

What does the research actually say?

A Reddit comment and a randomized human trial are not the same level of evidence. Every guide here separates them, labels them, and links to the source.

Weaker evidence isn't worthless — it's just less certain, and you deserve to know which kind you're reading before you act on it.

  1. 1Human randomized and controlled trials
