IGF-1 LR3 1MG
IGF-1 LR3 is a long-acting, highly bioavailable analog of natural IGF-1. IGF-1 is the primary downstream mediator of growth hormone and the single most powerful anabolic signal in the human body for muscle repair, growth, and fat metabolism.

Who Might Use It in Research?
- Individuals exploring site-specific muscle hyperplasia
- Researchers focused on extreme lean gains & pumps
- Those studying localized growth & recovery
- Anti-aging / longevity protocols
- Performance & body-composition optimization
How Does It Work?
- Binds to IGF-1 receptors which powerfully stimulates muscle satellite cell activation, protein synthesis, and hyperplasia (new muscle fibers).
- The “LR3” modification prevents binding to IGFBP (binding proteins), dramatically increasing bioavailability of IGF-1.
What Researchers Typically Observe?
- Rapid lean muscle gains & improved muscle fullness
- Enhanced recovery & reduced soreness
- Localized growth when injected into specific muscles (bi-lateral)
- Improved pumps & vascularity
