ya no problem, ive run sd several times wit great results, i always went 10mg the first week and went up to 40mg by week 4 and usually that was it, the last couple cycles i started at 30 mg from day 1 and only ran it for 3 weeks then briged to something less toxic like epi or hdrol and i would run that for another 3 to 4 weeks and i had great results wit that. make sure you have a proper pct either clomid or nolva otherwise youll lose all ur gains and mostlikly end up wit gyno
