IGF-1 LR3 Reconstitution & Dosing
Quick answer: mix a 1 mg vial of IGF-1 LR3 with 2 ml of bacteriostatic water. That gives 0.50 mg/ml, so a typical 40 mcg dose is 8.0 units on a U-100 insulin syringe — about 25 doses per vial. Reported protocols range 20 mcg–50 mcg, daily, often post-training.
IGF-1 LR3 is a long-acting insulin-like growth factor analog. Doses are tiny (micrograms) and vials small (1 mg), so a reconstitution calculator matters more here than for almost any other peptide. Full overview: what is IGF-1 LR3? →

FAQ
How much bacteriostatic water do you add to IGF-1 LR3?+
Most protocols mix a 1 mg vial of IGF-1 LR3 with 2 ml of bacteriostatic water. This gives 0.50 mg/ml, so a typical 40 mcg dose is 8.0 units on a U-100 insulin syringe. More or less water is fine — it only changes the volume you draw, not the dose.
What is a typical IGF-1 LR3 dose?+
Commonly reported IGF-1 LR3 protocols use 20 mcg to 50 mcg, daily, often post-training, administered via subcutaneous injection. These are reference figures from published protocols, not medical advice — individual use should be guided by a healthcare provider.
How many doses are in a 1 mg vial of IGF-1 LR3?+
At 40 mcg per dose, a 1 mg vial contains about 25 doses, regardless of how much water you add.
How should IGF-1 LR3 be stored?+
Fragile molecule: refrigerate, avoid shaking, use within 2–4 weeks.
