IGF-1 DES 2mg x 10 Vials. IGF-1 DES refers to a truncated insulin-like-growth-factor-I form associated with removal of the amino-terminal 1–3 residues. It is therefore structurally distinct from parent IGF-1 and from the extended LR3 analogue. The truncation designation is part of the analytical identity. Pack: 10 vials. 2 mg per vial; 20 mg nominal total across 10 vials. Intended exclusively for controlled in vitro laboratory research; not for human or veterinary use.
