IGF-1 LR3
Long-acting IGF-1 analogue studied for growth factor signalling and cellular proliferation research.
Molecular reference
Research background
IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a modified analogue of IGF-1 with an extended half-life due to reduced binding to IGF binding proteins. It has been widely studied in cell biology and metabolic research.
Research has explored its role in cellular proliferation, satellite cell activation, and anabolic signalling pathways in research models. Its extended activity profile makes it a subject of significant interest in growth factor research.

Reconstitution
- Supplied as a lyophilized (freeze-dried) powder for laboratory reconstitution.
- Bacteriostatic water (0.9% benzyl alcohol) is the most common reconstitution solvent for multi-use research handling; sterile or acetic-acid solutions are used for specific compounds.
- Introduce solvent slowly against the vial wall rather than directly onto the powder, and allow it to dissolve without vigorous shaking.
- Use the reconstitution calculator to determine solvent volume for a target concentration in your protocol.
Storage & handling
- Lyophilized powder: store sealed at -20 °C for long-term stability; short periods at 2–8 °C are generally acceptable.
- Once reconstituted: refrigerate at 2–8 °C and protect from light; use within the compound-specific window noted on the COA.
- Avoid repeated freeze–thaw cycles of reconstituted solution.
- Keep away from direct light and heat at all times.
Purity & verification
Every Popular Peptides batch is third-party tested by HPLC and LC-MS with a published Certificate of Analysis (≥99% purity).
