IGF-1 LR3 dose calculator

Quick math example

A 1 mg vial mixed with 1 mL gives 1,000 mcg/mL. A 50 mcg dose is 0.05 mL, which equals 5 units on a U-100 syringe.

How the IGF-1 LR3 calculation works

IGF-1 LR3 vials are small — often 1 mg — and doses are tens of micrograms. The calculator converts the vial total to mcg, divides by water volume for concentration, then divides your target dose by that concentration.

• 1 mg vial = 1,000 mcg total
• 1,000 mcg / 1 mL = 1,000 mcg per mL
• 50 mcg target = 0.05 mL draw

IGF-1 LR3 1 mg vial with 1 mL example

A 1 mg IGF-1 LR3 vial mixed with 1 mL gives 1 mg/mL, or 1,000 mcg/mL.

A 50 mcg dose is 0.05 mL — 5 units on a U-100 syringe. A 100 mcg dose is 0.1 mL (10 units); a 20 mcg dose is 0.02 mL (2 units).

• 1 mg / 1 mL = 1,000 mcg/mL
• 50 mcg / 1,000 mcg per mL = 0.05 mL = 5 units
• 100 mcg / 1,000 mcg per mL = 0.1 mL = 10 units

Very small doses, precise draws

Because IGF-1 LR3 doses are tens of micrograms, the draw can be just a couple of units, where a one-unit error is a large percentage of the dose. Reconstituting with more water spreads the dose across more unit marks for easier measuring.

• Sub-100 mcg doses need careful measuring
• More BAC water = larger, easier-to-read draw
• A U-100 insulin syringe is the practical choice
