Dosing calculators

Accurate, transparent, and fully in your browser — nothing you enter is sent anywhere. Each tool shows the formula so you can verify every result.

Educational only — not medical advice. These calculators perform arithmetic on numbers you enter. They do not recommend doses. Correct dosing depends on the specific compound, purity, your health, and guidance from a licensed provider. Always confirm independently.

Reconstitution calculator

Vial strength + water added → how much to draw for your target dose.

Peptide in the vial (mg)

Bacteriostatic water added (mL)

Target dose (per injection)

Enter values to see the draw amount.

Formula: concentration = (mg × 1000) ÷ mL of water = mcg/mL. Draw volume = dose ÷ concentration. On a U-100 syringe, 1 mL = 100 units.

Dose & unit converter

Convert between mg, mcg, and syringe units. Unit mix-ups cause the most errors.

Amount

Units

Concentration (mg/mL — optional, for syringe units)

Enter an amount to convert.

1 mg = 1000 mcg. Syringe units = (mcg ÷ (mg/mL × 1000)) × 100.

Supply / duration calculator

How many doses a vial holds and how long it lasts.

Vial strength (mg)

Dose each time

Times per week

Enter values to estimate supply.

Doses = (mg × 1000) ÷ dose. Weeks = doses ÷ per-week.

Half-life visualiser

See how a dose clears over time (exponential decay).

Starting dose

Half-life (hours)

Enter a dose and half-life to plot the curve.

A(t) = A₀ × (½)^(t ÷ half-life). After ~5 half-lives a compound is effectively cleared.
