IGF LONGR 1000 MCG
IGF1 LR3 (Long R3 Insulin-like Growth Factor) stands as a polypeptide hormone bearing striking resemblance to insulin. However, LR3 represents a modified version of IGF1 meticulously engineered to prolong its half-life and evade deactivation due to protein binding. Boasting 83 amino acids with Arginine substitution at position 3 instead of Glutamic acid, IGF1 LR3 exhibits enhanced stability and extended duration in circulation.
