IGF-1 LR3 is a modified version of IGF-1 with 83 amino acids instead of 70, giving it a significantly longer half-life and greater potency.

How It Works

IGF-1 LR3 promotes hyperplasia (new muscle cell formation), not just hypertrophy, making it uniquely powerful for muscle growth.

Research Benefits

Dosing

20-100mcg daily, injected post-workout or bilaterally into target muscles.

Research-grade peptides contain only the active ingredient and are NOT equivalent to FDA-approved pharmaceuticals.
