About IGF-1 LR3
- What it is
- IGF-1 LR3 is a synthetic, elongated analog of insulin-like growth factor 1 carrying an arginine substitution and a 13 amino acid N-terminal extension. These changes sharply reduce its binding to IGF binding proteins, leaving more of the molecule free to activate the IGF-1 receptor and drive cell growth. It is used mainly as a laboratory and animal research reagent to study cell proliferation and anabolic signaling. It has no approval for human use.
- How it works
- It binds the IGF-1 receptor while resisting IGF binding proteins, prolonging anabolic and cell growth signaling.
- Researched for
- Cell proliferation research; anabolic signaling; muscle growth; tissue growth
- Half-life
- Not established in humans
- Familiarity
- Advanced
- Research evidence
- Animal studies only
- Regulatory status
- Preclinical
- Key risk
- Its insulin-like activity can lower blood glucose, and its long-term safety in humans is not characterized.
Disclosure. Some vendors above are Peptul partners and pay us a commission when you buy through our link. Rows are ordered by: Peptul partners first, then what is in stock, then single vials before multi-vial packs, then price per milligram. Paying us moves a vendor up this order and changes nothing else - not their trust tier, COA badge, Peptul Score or reviews, which come from evidence and are worked out the same way for everyone. Available discount codes are shown beside the prices above. Discounted prices require the displayed code where indicated.
