Peptide Reconstitution Calculator

Enter your own numbers — this tool does the arithmetic, it does not tell you what dose to use.

How the math works

Concentration = peptide amount (mg) ÷ water added (mL), converted to mcg/mL. Volume to draw = your dose ÷ concentration. A standard U-100 insulin syringe reads 100 units per mL, so units = mL to draw × 100. More water dilutes the same peptide across a bigger volume — lower concentration, more units per dose.

Common questions

How does this calculator work? It divides the total peptide in the vial by the water you add, giving a concentration, then converts your chosen dose into syringe units based on a standard U-100 insulin syringe.

Does this tell me what dose to take? No — it only does math on numbers you enter. It doesn't recommend, suggest, or validate any dose; that's outside its scope.

What syringe does this assume? A standard U-100 insulin syringe (100 units = 1 mL), the most common type used with reconstituted peptides.

Is this specific to Growth Guys? No — the math applies to any peptide vial from any vendor. It's published here because this site covers Growth Guys sourcing and testing topics generally.
