How IGF-1 LR3 Works for Women
IGF-1 LR3 is a modified form of Insulin-like Growth Factor-1 with 3x higher potency and a 20–30x longer half-life than native IGF-1. For women, it provides a direct pathway to muscle preservation, body recomposition, and anti-aging that is independen
Dosage Protocol for Women
