Insulin-like Growth Factor Long Arg3, better known as IGF LR3, is one of the most studied synthetic analogs of IGF-1 in peptide research. With its enhanced stability and extended half-life, IGF LR3 is commonly used in laboratory models to explore cellular growth, repair, and metabolic function.
If you’re a qualified researcher searching for where to get IGF LR3, the answer begins with understanding what to look for in a reliable, science-forward peptide supplier. At Elevated Peptides, we offer research-only, high-purity IGF LR3—manufactured in the USA and third-party tested for identity and consistency.
What Is IGF LR3?
IGF LR3 is a recombinant peptide analog of human IGF-1 (Insulin-like Growth Factor 1), with two key modifications:
- Substitution of arginine at position 3 (Arg3)
- An extended amino acid chain (83 vs. 70 in native IGF-1)
These changes significantly enhance its biological activity and half-life, making it approximately 2–3 times more potent than native IGF-1 in stimulating cell growth in vitro. The extended structure also reduces binding to IGF-binding proteins, allowing for more free IGF LR3 to interact with receptors.
Research Applications of IGF LR3
IGF LR3 is primarily used in in vitro and in vivo studies investigating:
- Cellular growth and differentiation
- Protein synthesis and anabolic signaling
- Muscle regeneration and hypertrophy models
- Glucose metabolism and insulin sensitivity
- Neurological and developmental biology
IGF LR3 binds to the IGF-1 receptor and initiates a signaling cascade that affects gene expression, nutrient uptake, and protein production. This makes it a valuable research tool in regenerative medicine, endocrinology, and metabolic health.
Where to Get IGF LR3: What to Look For
When sourcing IGF LR3 for your laboratory or research institution, consider the following:
✅ Purity and Testing
Only purchase peptides that are ≥98% pure and come with a Certificate of Analysis (COA) from a third-party laboratory. Impurities can compromise the reliability and reproducibility of your data.
✅ USA Manufacturing
Domestic manufacturing often ensures more rigorous quality control than offshore alternatives. It also reduces transit time and exposure to unfavorable shipping conditions.
✅ No Binders or Additives
Research-grade peptides should be free of fillers, preservatives, or tri-fluoroacetate (TFA), which may interfere with experimental results.
✅ Clear Research-Only Labeling
A reputable supplier will clearly state that the peptide is not for human or veterinary use and is intended for laboratory research only.
