Peptide Calculator
Peptide calculator for research peptides
Enter your vial size, the volume of bacteriostatic water you mixed it with, and your target dose. We'll tell you exactly how many units to draw on a standard insulin syringe — plus the cost-per-day breakdown below.
Tip: 1 mg = 1,000 mcg. A 250 mcg dose = 0.25 mg.
Draw this much
10.0
units on a U-100 (1 ml insulin) syringe
How the math works: Vial size (mg) × 1,000 = total mcg in the vial. Divide by ml of BAC water to get the concentration (mcg/ml). Your target dose (mcg) ÷ concentration = ml to draw. Multiply by 100 for units on a U-100 insulin syringe.
For research use only. This tool is provided for laboratory professionals. Always verify against your protocol and your vial's COA.
Cost-per-day calculator
Work out the real €/day on any kit
The bigger the mg per vial, the longer it lasts — so larger kits work out cheaper per day. A 5 mg vial typically lasts ~60 days, a 10 mg vial ~120 days, and so on.

Less than a cup of coffee.
Tip: try the same kit price at 5 mg vs 10 mg vs 20 mg — you'll see the €/day drop sharply as vial strength increases.
