Yannick, could tell us again what your current E2 score is? Not sure what prompted you to go the letro route. I have experience with it, and I can assure you that there is very little margin for error with the stuff. Arimidex is so much more easy to work with, and more easy to manage when trying to get your E2 dialed in. You're making your journey a little bit complicated (IMO) with some of these choices. Also, 3 bottles?? Are you stocking up for the apocalypse?
