Doing 20 weeks using Rowlands slingshot method in march, starting on test prop 500 mg week, i was going to add in deca at maybe 400 mg or 300 at weeks 11-20, im also debating using masteron for the last 6 or 8 weeks of the course, ive read a lot of great stuff about it. Does anyone have experience running these 3 compounds? Ive allready got some pharma grade deca and all my prop ready to go but im having second thoughts about using the deca now, i might just leave out the deca all together and add masteron in at 50 mg eod at week 11 when i start my second blast phase, also.... would i need to carry on taking arimidex if i added in the masteron and left out the deca?? cheers
