Your Peptide.
Your Exact Dose.

Click on any category in the left panel to expand it, then click the peptide you purchased. The middle column will show you everything about it — vial size, recommended water, dosing frequency — and the calculator on the right auto-fills. Click a dose preset (Low / Standard / High) and your syringe draw amount appears instantly. No prior knowledge needed.

Bacteriostatic water (BW) is sterile water preserved with 0.9% benzyl alcohol that prevents bacterial growth. It is the standard solvent for reconstituting lyophilised peptides and extends shelf life to 28–30 days once refrigerated. Do not use plain sterile water or saline.

Insulin syringes are marked in units, not mL. On a standard 100-unit syringe, 10 units = 0.1 mL. The gold line on the syringe diagram shows exactly which graduation to pull the plunger to. The calculator shows both units and mL for clarity.

Low is the conservative starting dose — ideal for first-time use. Standard is the most commonly referenced dose in research. High is the upper end of the typical research range. All values are pre-loaded per peptide. You can always type a custom value instead.

After reconstitution store at 2–8 °C (36–46 °F) and use within 28–30 days. Keep away from light. Never freeze a reconstituted peptide — this damages the structure. Dry lyophilised peptides can be stored at −20 °C for much longer.

1 mg = 1,000 mcg. Vials are typically labelled in mg (e.g. 5 mg) while doses are often in mcg (e.g. 250 mcg). The calculator handles this conversion automatically — just select the correct unit in the dropdown next to each field.

The 1.0 mL / 100-unit insulin syringe is the most commonly used — it has the most graduation marks for precise dosing. The 0.5 mL / 50-unit is useful for smaller draw volumes. When in doubt, start with the 100-unit syringe.
