IGF-1LR3
IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a synthetic peptide hormone used primarily in bodybuilding and performance enhancement.
Here are key points about it:
Structure: Modified version of IGF-1 LR3 with an extended half-life (20-30 hours) due to an arginine substitution at position 3 and a 13-amino acid extension at the N-terminus.
Function: Promotes muscle growth (hypertrophy) and repair by stimulating protein synthesis and cell proliferation.
Benefits:
Enhances muscle mass and strength. Improves recovery from intense exercise. May support fat loss by increasing metabolism. Potentially aids in injury healing (e.g., tendons, ligaments).
