Just out of curiosity, how did you does your SD, etc. during that cycle?
I understand the two reasons given for using a thermogenic (1) fat burn (2) energy... I just don't think its use will be particularly effective during a SD cycle in either regard... and for some people, could add to side effects (particularly BP)... also, since thermogenic stimulant products 'burn' fat primarily through appetite suppression and increased caloric expenditure, that would seem counter to a bulk as well.
My view would be to use a thermo and also something like Lean Xtreme post-cycle, while you're using your anti-estrogen, etc. -- all together, they should help you 'lean out' your gains and also drop any water held at that time. Of course, this is just one view and I wouldn't say it was the only or 'the best' way for everyone.
