What is IGF-1 LR3?
| HALF-LIFE | 20–30 hours |
| MECHANISM | Receptor agonist |
| PRIMARY RESEARCH AREA | Anabolic / metabolic |
| ADMINISTRATION | SubQ / IM daily |
IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is currently being studied for muscle hypertrophy research, recovery support, body recomposition, nutrient partitioning, and performance and anabolic signaling research.
Unlike short-acting IGF-1, LR3 has an extended half-life allowing prolonged activity.
Reconstitution Guide
SUGGESTED RECONSTITUTION
1mg IGF-1 LR3 + 2mL Bacteriostatic Water
CONCENTRATION AFTER MIXING
- · 1 unit = 5mcg
- · 10 units = 50mcg
ALTERNATIVE RECON
- · 1mL = 10mcg per unit
- · 3mL = 3.3mcg per unit
Research Dosing Format
| PHASE | DOSE | UNITS (2mL) |
