Overview

IGF-1 LR3 is a long-acting analogue of insulin-like growth factor 1 with an extended half-life (~20 hours). It is a potent anabolic peptide that drives muscle hypertrophy and fat loss.

Mechanism of Action

Binds to IGF-1 receptors in muscle tissue, promoting protein synthesis, satellite cell activation, and muscle hypertrophy. Inhibits apoptosis and stimulates glucose uptake.

Key Benefits
  • Promotes significant muscle hypertrophy
  • Increases satellite cell activation
  • Reduces fat mass
  • Synergistic with GH secretagogues
Side Effects

Hypoglycaemia (especially without adequate carbohydrate intake), jaw pain, organ growth with long-term use at high doses.

Suggested Protocol

20–50 mcg IM or SubQ post-workout, 5 days on, 2 days off. Consume fast-acting carbohydrates immediately after injection.
