gradually work your way up with clen... try starting at like 60 and work your way up to 120... ppl are effected differently from it and if you jump to a large dose you will feel the side effects.
If i were you id either buy another vile of that Winstrol (winny) (excellent choice), or try 25mg ED because the active life is only 48 hrs and your blood levels will peak the injection day, then it will barely be in your system the next day.
