Description
IGF-1LR3
Supplied as a lyophilized powder that must be reconstituted with bacteriostatic water prior to research use.
What Is IGF‑1 LR3?
IGF‑1 LR3 (Insulin-Like Growth Factor 1 Long R3) is a synthetic analog of IGF-1 with a longer half-life and enhanced biological activity. It is primarily studied for its effects on muscle growth, cellular repair, metabolism, and neuroprotection
.
Muscle Growth & Recovery
Stimulates muscle cell growth (hyperplasia) and repair
Supports lean muscle development and accelerates recovery after training
Cellular Repair & Regeneration
-Promotes repair and regeneration of nerves, skin, tendons, and bone
-Plays a role in cell proliferation, differentiation, and cellular anti-aging processes
Fat Loss & Metabolic Support
-Enhances fat metabolism and helps improve body composition
-Directs nutrients toward muscle growth rather than fat storage
Neuroprotective Potential
-Investigated for brain health, influencing cognition, neurogenesis, and protection of neural tissue
⚠️ Important Notes
–Research-use only: not FDA-approved for human or clinical use
-Has a longer half-life (~20–30 hours) than natural IGF-1, allowing for more sustained effects
-Potential side effects may include joint discomfort, low blood sugar (hypoglycemia), or abnormal tissue growth if misused
