IGF-1 LR3
A long-acting IGF-1 analog studied in growth-signaling research.
Overview
IGF-1 LR3 is a synthetic analog of Insulin-like Growth Factor 1 modified for an extended half-life. In research literature it is studied for its interactions with the IGF-1 receptor and downstream growth-signaling pathways. It is a commonly referenced compound in growth-factor research contexts.
Referenced research ranges
20–50 mcg, once daily — research protocols reference timing relative to activity in the literature
Reconstitution default
1 mg in 1 mL yields 1 mg/mL (1000 mcg/mL); a 50 mcg reference dose is 0.05 mL (5 units on a U-100 syringe).
Storage
Store lyophilized vials refrigerated; refrigerate after reconstitution and protect from light.
Considerations
- Extended half-life relative to native IGF-1.
- Small reference draw volumes, so precise measurement is commonly noted.
- Reconstituted peptide is temperature-sensitive and light-sensitive.
