Use consistently for 4-6 weeks, then cycle off for a month

In practical terms, IGF1 LR3 shows greatly greater potency than native IGF-1 in most research uses

Comparative investigations utilize these compounds to examine differences in receptor activation mechanisms, downstream signaling architecture, ligand selectivity, and pathway-specific signal transduction.
