Hey, Crimson......sorry to be late answering you, the board has been running so slow lately, I just haven't been on. George says he is fixing it, maybe just my server?
I'll stay out of the receptor fray - I think the answer there is well settled.
To answer your question, it depends on if you are looking to recover between cycles, or don't care like me.
If you want to restore your axis between cycles, try a bridge with GH, insulin, and light anavar doses (clomid of course, too)
I take a month in between 12 week cycles and use less toxic stuff, but haven't really been "off" in years. No, I'm not advocating this....just my personal choice.
Sustanon is always good if you don't plan to seek recovery for a while, cause test and GH are very synergistic. Insulin, also.
