Bond Peptides IGF1-LR3 2MG Nasal Spray


IGF-1 LR3, a synthetic variant of insulin-like growth factor-1, is reengineered for enhanced performance with an extended active life, boosting cellular growth, fat metabolism, muscle repair, and hypertrophy while effectively inhibiting myostatin. Its application extends beyond muscle building, showing promise for improving lactation, highlighting its versatility in health and growth research in animals. IGF-1 LR3 stands out in the field of advanced research for its contributions to cellular development, repair processes, and metabolic efficiency.

SKU: BP-NS-IGF1LR3-2MG Category: Brand:

IGF-1 LR3 (insulin-like growth factor-1 long arginine 3) is a synthetic, modified construct of insulin-like growth factor-1. Because IGF-1 LR3 does not bind to IGF-1 binding proteins very well, it remains active up to 120 times longer than standard IGF-1. This results in improved half-life for the peptide and thus increased activity. IGF-1 LR3 enhances cell division and growth, boosts fat metabolism, and increases muscle repair and hypertrophy by inhibiting myostatin. Recent research suggests that IGF-1 LR3 may also be useful in improving lactation among mothers with young offspring.
