This is just a general question and no i am not a steroid user nor am i thinking about using them anytime soon but i have a few friends i train with who use them who are not members on this forums but basically 1 of my friends says he thinks 12 weeks is better with 1 injection per week as it's in your system for longer whereas the other friend says 6 weeks with 2 injections per week is better because you're getting it into your system quicker and it's safer because you're doing it for a shorter duration so there is less side effects they both cycle similar things test cyp and deca but one takes dianobol for 6 weeks too the one who does the 12 week cycle and the other just does test and deca for 6 weeks. Again this is purely research and it's not to do with me so please don't flame i'm not an idiot or thinking about doing any cycles as i am researching like i am doing now.
