My first cycle at 25 & I ran test cyp & decca, Ran 1cc of each, by my 3rd week jump up 2cc each by my 6th week jumped up to 2 1/2 3cc each & stayed at that for 6-8 months got off for awhile & back on. Never had no problems. make sure you take something like milk thistle daily also! I'm not trying to sound awful or anything like that. I thought this was a message board!
