Thanks for the advice, i only use every few years or so....(or after I feel myself putting on too much weight), and I only use for one cutting cycle....Then I stop, but due to a chemical immune blocker my metabolism slows down to more than half the normal rate. I use to use hydroxycut, but that shit is garbage now and having to to take 6-8 pills a day is too hard on my liver. So now I just use clen. My doctor use to have me on a all natural roid, but the manufactuer stopped making it.
