Ok, I may be wrong but I was doing some reading and I'm just going to throw my findings out there. Superdrol is just a estrogen inhibitor just like anastrozol (arimidex/nolvedex) Correct? Superdrol is a methylated (oral/metabolized) non steroidal compound. Superdrol is a derivative of Masteron which is not methylated, and was designed originally for breast cancer due to its estrogen inhibiting properties. This is why Superdrol will not aromatize because its NOT testosterone and is ALREADY an estrogen inhibitor. This is why Masteron and Superdrol is stacked with testosterone steroids and prohormones. This is confusing why people are talking about PCT after a cycle of SD. SD is not androgenic, its anabolic, due to the fact it will raise testosterone levels by suppressing estrogen levels inhibiting enzymes from producing estrogen. If my assumption is wrong, I am sorry for the rant but I think I'm on track here. Also anyone high on taking anti ests all the time, they better rethink their strategy. Estrogen plays a huge part in the male body. Cardiovascular health and bone density are just to major factors. You may end up breaking a hip in your 40s because your bone density is weaksauce due to all the anti ests you took for years.
