Our premium-grade IGF-1-LR3 (Insulin-like Growth Factor-1 Long Arg3) is a highly purified, synthetic recombinant analog of human IGF-1. It has been specifically modified with an arginine substitution at position 3 and a 13-amino-acid extension at the N-terminus. This specialized modification is designed for advanced research to dramatically extend its active life in the body by preventing it from binding to restrictive proteins.
In practical terms, IGF-1-LR3 is one of the most powerful compounds studied for muscle preservation and cellular growth. Unlike standard growth factors, its extended half-life (about 20 to 30 hours) allows it to remain active throughout the day, constantly signaling muscle tissue to repair and grow. It works by encouraging “hyperplasia”—the actual creation of brand-new muscle cells rather than just making existing ones larger. Additionally, it acts as a master nutrient shuttler, directing proteins, amino acids, and carbohydrates straight into muscle cells to fuel recovery and strength, while actively preventing them from being stored as body fat. This makes it an exceptional research tool for evaluating rapid recovery, anti-muscle-wasting protocols, and cellular rejuvenation.
- Purity: 98% or higher (HPLC verified)
- Format: Lyophilized (freeze-dried) white powder

Quick Storage & Reconstitution
- Reconstitution: Dissolve in sterile water, sterile bacteriostatic water, or a weak acetic acid solution as required by your laboratory protocol. Swirl gently; do not shake to prevent peptide degradation.
- Before Reconstitution: Store desiccated at 2C to 8C (36F to 46F) for short-term, or frozen below -20C (-4F) for long-term storage (up to 24 months).
- After Reconstitution: Store at 2C to 8C (36F to 46F) and use within 14 to 21 days. Do not freeze after reconstitution.
