Growth Hormone
Growth Hormone Dose Calculator
Growth hormone dose calculator. Get the exact syringe draw for any HGH vial in seconds. IU to mg conversion + exact syringe draw for any HGH vial. Works with 10 IU, 36 IU, and custom sizes.
Quick answer: 1 mg HGH = 3 IU. 1 IU HGH = 0.333 mg. For a 10 IU vial + 1 mL BAC water at 2 IU/day: draw to the 20-unit line on a 100-unit insulin syringe.

Frequently Asked
How do I calculate growth hormone dose?
Divide your vial IU by BAC water mL to get concentration. Then divide your target dose (IU) by the concentration to get draw volume (mL). Multiply by 100 for the unit line on a 100-unit syringe. The calculator above does this instantly.
How many mg is 1 IU of growth hormone?
1 IU of somatropin (recombinant HGH) equals approximately 0.333 mg. So 1 mg = 3 IU. This conversion applies to all brands of recombinant human growth hormone.
How many syringe units do I draw for 2 IU?
With a 10 IU vial + 1 mL BAC water: concentration = 10 IU/mL. For 2 IU: draw 0.2 mL = 20 units on a 100-unit syringe. With 2 mL BAC water: concentration = 5 IU/mL, draw 0.4 mL = 40 units. Use the calculator above for any combination.
How many doses are in a 10 IU vial?
At 2 IU/day: 5 doses. At 1 IU/day: 10 doses. At 3 IU/day: 3 doses. A 36 IU vial at 2 IU/day lasts 18 days.
How do I reconstitute growth hormone?
Draw 1-2 mL of bacteriostatic water into a syringe. Inject slowly down the inside wall of the vial, not directly onto the powder. Swirl gently until dissolved; never shake. Refrigerate at 2-8C. Use within 20-30 days.
What is the difference between HGH and GH secretagogues?
Somatropin (HGH) is synthetic recombinant growth hormone that directly replaces endogenous GH. GH secretagogues (Ipamorelin, CJC-1295, Sermorelin) stimulate the pituitary to produce more of its own GH. Secretagogues are dosed in mcg, not IU. See the comparison page for all GH-axis calculators.
