Unfortunately I decided to stop my first cycle. Can not stand the side effects. I made only 2 pin of sustanon day 1 and day 4. Arimidex 0.25 from day 4 . Today is the day 12. I will not pct, but arimidex long as I keep taking it? I had to stop the cycle causes anxiety, chest pain, nipple fire, which I still have today. The first few days were the worst because I could not train had fever fatigue malaise. But chest pain is still present and nipple annoying.
