IGF-1LR3

IGF-1 LR3 – Unlock Growth. Redefine Recovery.

IGF-1 LR3 (Insulin-like Growth Factor 1 Long R3) is a potent peptide analogue of naturally occurring IGF-1, engineered to promote muscle growth, fat metabolism, and enhanced recovery. With a longer half-life and greater bioavailability than native IGF-1, LR3 stays active in the body for up to 20+ hours — allowing for extended anabolic signalling and superior results.

IGF-1 plays a key role in cell growth, muscle repair, and regeneration. LR3’s enhanced stability allows it to support lean mass development, improve insulin sensitivity, and accelerate recovery between workouts. It’s often used in conjunction with GH peptides or bulking protocols for maximum tissue growth and performance output.
