Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Every vendor on this page is verified for endotoxin testing — not just HPLC purity.
Francis et al. (1992) characterized LR3-IGF-1's enhanced potency due to reduced IGFBP binding. Tomas et al. (2001) demonstrated enhanced muscle protein synthesis and reduced protein degradation in vivo. The peptide is widely studied in muscle biology, cachexia, and wasting disease research. Hypoglycemia is the most significant acute safety concern. Prolonged use at high doses has been associated with organ growth (gut distension, jaw growth) in anecdotal reports. Banned by WADA and classified as a prohibited growth factor.
