IGF-1 DES

FDA: research-only

IGF-1 DES is a short-acting splice variant of IGF-1 with strong affinity for injured tissues. It works best when injected directly into target muscle to promote localized growth and satellite cell proliferation, making it ideal for site-specific hypertrophy. Short half-life provides localized action on trained muscle. Strong affinity for injured tissues promotes targeted repair. Inhibits myostatin when combined with Follistatin-344. Activates satellite cell proliferation for site-specific muscle growth. More potent than LR3 for localized effects but shorter duration. - Localized muscle growth and hypertrophy - Post-session gains in target muscle groups - Sprint power enhancement - Site-specific tissue repair -
