OK, I've run 2 SD cycles over the past 18 months. Had great results from both. Now I have some M1T as well as my normal SD supply. So, I was planning on running a 3 week cycle of M1T starting Feb. Would there be any sense in stacking SD after the M1T cycle? Like 3 weeks of M1T then jump to the SD? or should I just do a 3 week cycle then my normal PCT and time off and then do a SD cycle?
