IGF-1 LR3: Research Profile, Dosages & Supplier Prices
IGF-1 LR3 is a growth factor research compound with a molecular weight of 9117.5 g/mol and a research half-life of 20-30 hours in research models (versus ~15 minutes for native igf-1). IGF-1 LR3 is a recombinant analog of insulin-like growth factor 1, engineered with an Arg3 substitution and a 13-amino-acid N-terminal extension that dramatically reduces binding to IGF binding proteins - extending its research half-life from minutes to over a day.

| Sequence | 83-amino-acid IGF-1 analog (Glu3 to Arg substitution plus 13-residue N-terminal extension) |
| Formula | C400H625N111O115S9 |
| Mol. weight | 9117.5 g/mol |
| Half-life | 20-30 hours in research models (versus ~15 minutes for native IGF-1) |
| Forms sold | Lyophilized vial (typically 0.1mg or 1mg) |
What is IGF-1 LR3?
It is one of the most potent anabolic signaling compounds in research, studied in muscle hypertrophy models, cell culture media supplementation, and metabolic research. It is also a standard cell culture reagent with legitimate industrial demand.
IGF-1 LR3 is a large recombinant protein, not a simple synthetic peptide - it requires expression systems to manufacture. This makes it expensive and makes mass spec verification particularly important, as substitution with cheaper peptides is a known scam.
Mechanism of Action (Research Context)
IGF-1 receptor agonist with reduced IGFBP binding, studied for sustained anabolic signaling through PI3K/Akt/mTOR pathways in cell and animal models.
Research Areas
IGF-1 LR3 Dosages in Research
Published preclinical research used microgram-range dosing. Research vials are typically 0.1mg and 1mg - much smaller than standard peptide vials because of potency. Laboratory research use only.
Dosage information is a summary of published laboratory research and is provided for informational purposes only. These compounds are not for human use.
Storage & Handling
Lyophilized: -20C or -80C long-term. Reconstituted: 2-8C, use within 7-14 days - less stable than small peptides once reconstituted.
