6 months.....you are not ready for steroids (not to mention I don't even know how old you are). You should have at least 2 years of good training under your belt, a top notch diet, and be at least 20 yrs. old to start using AAS, IMHO.
Having said that, all ethics aside...no test (yes, shots!) = no cycle. The compounds you mentioned above are great, granted you use the correctly.
If you are not ready to pin, you aren't ready to use AAS. You have not done any research, if you have...you would not post such questions. Please do some research. Good luck.
