i have done 4 courses 2 month on 2 off .i had a 3 month gap between the 2nd and 3rd course but this time i havent made any more gains than i did last time ive gone from 10 stone to twelve stone 7 in around 1 and a half years but i weighed 12.10 on my last course then lost it all,this time i havent even hit that only 12 stone 7 i have never done anything but sus and deca and the last two times i did d bol 5 a day for about 6 weeks.i have never done any pct after a course.i think its either im used to this stack or my natural test is shot and is not reaching normal before my next stack. im in week 6 of the 4th course and still between 12 stone 7-8 thanks
