Peptide calculator

Precision dilution maths, half-life curves, and cycle calendars. No sign-up. All calculations run locally in your browser — nothing is sent to us.

Inputs

Peptide Vial size (mg) Bacteriostatic water (mL) Target dose

Results

Concentration

5 mg/mL

Volume per dose

0.2 mL

Units (U-100 syringe)

20 u

Doses per vial

10 doses

Draw level on U-100 insulin syringe

Standard formulas. Concentration = vial mg ÷ BAC mL. Volume per dose = dose mg ÷ concentration. Units on a U-100 syringe = mL × 100. All maths runs in your browser.

Inputs

Peptide Dose per injection (mg) Dosing frequency

Half-life: ~5 days. Steady state reached in ~25 days. Residual at 24 h shown on the right.

Decay curve

Residual amount (% of dose) X axis: hours after injection

Time after dose	Residual	Steady-state stack

Inputs

Peptide Start date Days on Days off (washout) Number of cycles
