TweetHas anyone that has ever used hgh gotten any lumps at the site. I am in my third week now and almost every shot i get a marble sized lump right where i injected that lasts for 3 days or so. There a little sore like a bruise but not real bad. I have been injecting in the belly and rotation around a little. I just wish i would quit getting these damn bumps so if anyone has any ideas i would appreciate it.
