Peptide Calculator Guides
Short, exact guides to the arithmetic behind peptide calculations. Each one links to the calculator that does the work.
All guides
- GuideHow to Use a Peptide CalculatorYou need three numbers: the amount in the vial, the liquid you added, and the amount you want a volume for.
- GuideHow to Reconstitute Peptides: The MathReconstituting a peptide means dissolving the powder in a measured volume of liquid, usually bacteriostatic water.
- GuideInsulin Syringe Units ExplainedOn a U-100 syringe, 1 mL is 100 units, so 1 unit is 0.01 mL.
- GuideHow Much Bacteriostatic Water to AddThere is no single correct volume.
- GuideBacteriostatic Water ExplainedBacteriostatic water is sterile water with a small amount of preservative, usually 0.9% benzyl alcohol, which slows bacterial growth so a vial can be entered more than once.
- GuideBlend Vial Math: Each Peptide in One VolumeIn a blend vial all components dissolve in the same liquid, so any volume contains every component in the vial’s own proportions.
- GuideRetatrutide Calculator Questions, Answered CarefullyRetatrutide is an investigational drug: it is not FDA-approved, and no approved product or label exists.
