IGF-1 LR3

IGF-1 LR3 is a long-acting form of insulin-like growth factor-1 known for its strong effects on muscle growth, cellular repair, and nutrient utilization. It supports muscle hyperplasia, recovery, and enhanced anabolic signaling, particularly around training.

Common dosing (*research + anecdote):
• 20–50 mcg per day (conservative use)
• 50–100 mcg per day (moderate use)
Typically used 5 days per week, often post-training administered locally into trained muscles.
