Peptide Tools
Interactive calculators and checkers for athletes doing their own homework on recovery peptides. Each one runs entirely on your device — no account, no tracking of what you enter — and each is built to be honest first: the math is transparent, the anti-doping framing is straight, and every tool tells you where it stops and a clinician begins.
- The calculator
Peptide Calculator
Reconstitution and dose in one place, because they are one job in sequence. Get the concentration from a vial and a water volume, convert an amount into U-100 syringe units, see doses per vial and cost per dose — or solve the water volume backwards from the mark you want to read. Every field starts blank: it converts your numbers and never proposes one.

Tirzepatide Reconstitution Calculator
The same engine with tirzepatide vial strengths and milligrams preselected. A 30 mg vial in 1.5 mL is 20 mg/mL, so each unit mark carries 0.2 mg — which is why the water volume decides how much a misread mark costs.

Semaglutide Reconstitution Calculator
Built around the sub-milligram case, where one misread unit mark is a rounding error against 2.5 mg and a tenth of the figure against 0.25 mg. Concentration first, always — units on their own never describe an amount.

Retatrutide Reconstitution Calculator
The same arithmetic for an investigational compound with no approved product, no approved labelling and no established dose anywhere in the world. The maths works; that is the least of what is unverified here.
Open the calculator - Dosing math
BPC-157 Dosage Calculator
Microgram-scale work, so it leads with micrograms per unit mark: a 5 mg vial in 2 mL is 25 mcg per mark, which turns every later conversion into one division you can do in your head. Not a dose recommendation — there is no established human dose to recommend.

Bacteriostatic Water Calculator
The one decision you cannot take back. Solve the water volume from a target strength or backwards from a target syringe mark, plus what bacteriostatic water actually is — sterile water with 0.9% benzyl alcohol, and where the 28-day limit comes from.

WADA Prohibited-Status Checker
Pick or type a peptide to see its 2026 WADA status — prohibited class (S2/S0), Monitoring Program, or not addressed — with a plain note. A compliance reference for tested athletes, straight from the 2026 List.

One disclaimer for all of them
These tools are educational, not medical or anti-doping advice, and not a recommendation to use any peptide. Most research peptides are not FDA-approved, are sold on a grey market with unverified purity, and are prohibited in tested sport. Dosing and any decision to use a peptide must be directed by a licensed clinician, and anti-doping status must be confirmed against the live official WADA List and your own sport's rules. Verify every number and status before acting on it.
Read the research too
A calculator answers “how much”; the articles answer “whether,” “how safe,” and “is it even legal.” Start here:
