Either will work for you. Personally, I prefer using nolvadex because I don't like the way that clomid makes me feel. A lot of people feel estrogen type emotional side effects from clomid. Not cool! lol. So to avoid getting caught up in a movie marathon on the "lifetime : television for women" network, I run 40mg of nolvadex for 1 wk, followed by 2 more wks of nolvadex at 20mg. If I feel like I need to go a little longer, I may add 10 more days at 10mg. Through PCT, I will also take .25mg of adex EOD to help keep estrogen lower
For Sust 270, you'll start PCT 3 wks after your last shot.
