Ipamorelin
In people
In people, each dose gives one growth hormone peak about 40 minutes later, rising with the dose and clearing within a few hours. Taken at night, sleep deepens within the first week. Recovery after training speeds up and soreness eases by weeks 2 to 3. Over two to three months skin looks fuller, joints feel better and the waist comes in. Most people feel no hunger spike and no anxious, wired feeling, because cortisol stays flat.
