I was doion some research on masteron, although its not the best for bulking or great at all for its full affects unless your about 8%BF or less, but mast is an anit-estrogen and will help fight estrogen side effects when thrown in a cycle, which is finr since it is also low on the toxicity scale, and i read that you can take in a small dose around 100mg/week in your off cycle after pct and it will help you keep your gains. ok thats it
