| How often | Once a day |
| When | After training, with a carbohydrate meal |
| Steps up and down |
|
| How long | 4 weeks |
| Cycle | 4 weeks on, then 4 weeks off |
| Mixing | Add 1 mL bacteriostatic water (or 0.6 percent acetic acid) slowly down the side of the vial. Swirl, never shake. |
| Storage | Before mixing: freezer or fridge, dark. After mixing: fridge, use within 3 weeks. |
IGF-1 LR3 is injected under the skin, or into a trained muscle, once a day after training with a carbohydrate meal. Start at 20 mcg a day, build to 40 to 50 mcg a day, and run it for 4 weeks.
Dose calculator
Change any box to work out a different amount.
How it works: strength per mL = vial strength ÷ water added. mL to draw = dose ÷ strength per mL. Units on a U-100 insulin syringe = mL × 100 (1 mL = 100 units). Doses per vial = vial strength ÷ dose. 1 mg = 1000 mcg.
Your personal schedule is set after we review your survey.
