How to read it. Everything's in milligrams (mg) — the way most peptides are dosed today. Concentration is the peptide per mL after mixing (vial mg ÷ water mL). Your draw is your dose ÷ concentration, shown in both mL and insulin-syringe units (100 units = 1 mL). A misplaced decimal is a 10× error — always double-check against the vial.
Reference only — please read. This calculator performs reconstitution arithmetic from numbers you enter. It is educational information and is not medical, legal, or regulatory advice, a dosing recommendation, or a treatment or efficacy claim. It does not tell you whether, when, or how to use any substance. Many peptides are not FDA-approved and some are labeled research-use-only ("not for human use"). Verify every value independently and consult a licensed provider. Published by Health Pro Distributors. © 2026.
