Description
Sold as a lyophilized powder which must be reconstituted with bacteriostatic water.
IGF-1 LR3 (Insulin-Like Growth Factor 1 Long R3) is a synthetic analog of IGF-1, engineered to have a longer half-life and enhanced biological activity. It is primarily used in research settings for:
💪 Muscle Growth and Recovery
Stimulates muscle cell growth (hyperplasia) and repair, making it popular in performance and recovery-focused protocols.
Promotes lean muscle mass development and speeds up post-training recovery.
🧬 Cellular Regeneration
Supports the repair and regeneration of nerve tissue, skin, tendons, and bones.
Plays a key role in cell proliferation, differentiation, and anti-aging at the cellular level.
⚖️ Fat Reduction and Metabolism
Enhances fat metabolism and promotes a leaner body composition by improving nutrient partitioning (directing nutrients toward muscle growth rather than fat storage).
🧠 Neuroprotective Potential
Being explored for brain health, as IGF-1 pathways influence cognition, neurogenesis, and neuroprotection.
⚠️ Important Notes
Research-use only: Not FDA-approved for human or clinical use.
Has a much longer half-life (~20–30 hours) than natural IGF-1, allowing for more prolonged effects.
Potential side effects include joint pain, hypoglycemia, or organ growth if misused.
