IGF-1 LR3
Insulin-like Growth Factor 1 Long R3
Long-acting analogue of IGF-1. Directly activates IGF-1 receptors in muscle tissue, promoting satellite cell differentiation (muscle stem cells) and protein synthesis. 3x longer half-life than regular IGF-1.
Dose
10–20mcg per day SubQ or IM near trained muscle
Cycle
4–6 weeks on, 4–6 weeks off
Timing
Post-workout on training days, or morning on non-training days
Benefits & Effects
- ✓Satellite cell activation (permanent muscle fiber increase)
- ✓Enhanced nutrient partitioning
- ✓Direct anabolic effect independent of GH
- ✓Recovery enhancement
- ✓Anti-catabolic
Reconstitution & Dosing
Reconstitution
1mg + 3mL BAC = 333mcg/mL. Draw 3 units for 10mcg, 6 units for 20mcg.
Dose
10–20mcg per day SubQ or IM near trained muscle. Start at 10mcg.
Cycle Length
4–6 weeks on, 4–6 weeks off. IGF-1 receptor downregulation occurs with prolonged use.
Timing
Post-workout on training days, or morning on non-training days.
