Hell, 6 months is generally a basic cycle for me, if not a year. Just have somebody monitor your blood work every 2 months or so and dont get carried away. My cycles usually consist of 500-750mg/week of sust, 600mg/week of Eq, both as my base. The only thing I will switch up is if I decide to add some tren here or there for a while. I have been doing cycles like these for YEARS and NEVER had a problem. If I come off, it will only be for a couple of weeks to run some clomid or HCG. One of the other reasons I do long cycles of 6-12 months is because I am an avid user of HGH as one of my base drugs also. HGH needs to be taken for at least 6 months at a time or you're wasting your time and money. I know some people say I am crazy for this, but once you reach a certain point in your training and the results you want to acheive, 6 months will not seem like a long time.
