Have got good effects from running jintropin such as losing weight and sleeping better (maybe even a bit of muscles as my arms, legs and my chest seem to be bigger, not sure) but I am annoyed by the water retention and the headaches I get from using it. I wasn’t sure if these 2 effects I have from using it but when I looking it up online I saw that jintropin can make you have them. So all in all is good, but I just don’t like those annoying side effects.
