IGF-1 DES is a truncated variant of IGF-1 (des[1-3]) with reduced IGFBP-3 binding affinity, producing a stronger local effect at the injection site due to higher free-IGF-1 concentration.
The truncation reduces binding to IGFBP-3, allowing more free IGF-1 to interact with local IGF-1 receptors. Researchers use it for localized anabolic signaling rather than systemic IGF-1 elevation.
Commonly reported research ranges: 30–75 mcg per injection, pre- or post-workout local administration.
Dose should always be individualized. Factors that influence it include bodyweight, research goal, tolerance, and specific compound batch. The information below is educational, not a prescription.
A widely used reconstitution for a 1 mg vial is 1 ml of bacteriostatic water. With a typical 50 mcg dose this works out to the unit count shown in the calculator below.
Approximately 20–30 minutes.
This half-life informs how often IGF-1 DES is typically dosed. Shorter half-lives usually mean more frequent dosing to maintain plasma levels; longer half-lives allow daily, weekly, or less-frequent administration depending on the compound.
This list reflects effects reported in available literature or user logs. It is not exhaustive. Adverse reactions should be discussed with a qualified clinician.
Lyophilized: refrigerated. Reconstituted: refrigerated, use within 14 days.
