Anyone experience any sides with this stuff? If so, what dose, how long were you using. I experienced some soreness in injection area and after discontinuing it after about a week of use in which i started at 20mcg switching sides each day, and then doing 20 mcg twice a day rotating sides of the bellybutton. I now have hard spots under the skin in injection sites. Anyone else have anything like this??? Also I did not feel like this was near as strong as oral clen I have taken previously, but many people on hear were giving really good reviews.
