New to this? What "reconstitution" means

Your peptide arrives as a dry powder in a sealed vial. Before you can measure a dose, you mix it with bacteriostatic water (the "bac water" sold alongside it) to turn it into a liquid — this is called reconstitution.

This calculator does the math for you. Tell it a little about you, tap the intensity tier and cadence you want, and it tells you how much water to add and the exact line to fill your insulin syringe to. More water doesn't change the total medicine — it just spreads it out so small doses are easier to measure. Already mixed a different amount? Set it under Advanced.

Important — read before use. This tool performs arithmetic and shows commonly-cited reference ranges from research literature and community protocols. It is not medical advice and does not establish a safe or approved human dose. The intensity tiers, cadence conversion, and any weight-based figures are informational estimates built from published ranges — they are not personalized medical dosing. Every compound referenced here is sold strictly for laboratory research and in-vitro use and is not for human consumption. Dosing figures vary between sources and are not FDA-evaluated. Always confirm your actual vial strength against the product label/COA, and consult a licensed physician before any decision about a substance entering a human body.
