No changes. You are suppressed within 24-48 hours. IMO, six weeks is as short as I would get to receive max benefits from your AAS cycle. Many are doing four week cycles, but they are just as suppressed as someone doing 6-, 8 or even 10-week cycles.
DrJMW, I understand what you're saying about a person being equally supressed at 4 weeks or 8 weeks. However, are you also saying there is no difference in the time needed to rebound from a 4-week or 8-week cycle?
There aren't any studies to see whether recovery from a 4-week or a 6-week cycle should vary. I have been sticking with what works, no matter the aas used or the length of the cycle.
