Calculate precise peptide dosages, reconstitution ratios, and mcg to mg conversions
You never have to recalculate again.
Select your syringe volume, enter your peptide vial amount (mg), add the amount of bacteriostatic water you'll use, and enter your desired dose. The calculator will tell you exactly how many units to draw on your syringe.
1 mg = 1,000 mcg. To convert mcg to mg, divide by 1,000. To convert mg to mcg, multiply by 1,000. For example, 250 mcg = 0.25 mg.
Common amounts are 1ml, 2ml, or 3ml depending on your peptide vial size and desired concentration. A 5mg vial with 2ml of water gives you 2.5mg/ml concentration. More water = lower concentration = higher syringe units per measurement.
Most researchers use 0.3 mL, 0.5 mL, or 1.0 mL syringes with 0–100 unit marks for fine measurements.
1) Let the peptide vial reach room temperature. 2) Draw bacteriostatic water into your syringe. 3) Place the syringe tip against the inner vial wall and introduce solvent slowly; avoid spraying the powder. 4) Gently swirl to dissolve. 5) Use the calculator above to determine your measurement.

Yes! This peptide dosage calculator works for all research peptides regardless of type. The math is the same whether you're working with growth peptides, recovery peptides, or any other research compounds measured in mg/mcg.
