CJC-1295 may markedly increase plasma growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels in animals and humans. [1] [2] [3] [5] With a single injection, in human subjects, CJC-1295 DAC may increase plasma GH levels by 2- to 10-fold for 6 days or longer and plasma IGF-1 levels by 0.5- to 3-fold for 9 to 11 days.
