Kevin, a number of forum users can probably contribute their own opinions on this if they check the thread relates to prohormone use and Nanodrol specifically. We have seen several using OTC PCT only. Personally, I think the issues with the likes of tamoxifen and the great results forum members have had running OTC PCT means that an approach combining an AI with something like lean Xtreme and a testosterone booster should work well.
Here is an article on tamoxifen and why it is very much a double edged sword.
