This not my first cycle. I'm 25 5'10 210lbs at about 12% body fat and I was thinking about starting my first cycle of tren. I have read many threads and it says that tren is a strong progesterone and to take letrzole or fulvestrant in order to counter act this. Now do I take either of these estros during or after the cycle? Also, I was looking at cycling it for about 8-10 weeks so should I get the fast acting or the slower acting tren? Also, what is a good layout for the amount to take per a shot and should I buy 10 or 20ml? Just looking for some suggestions, and I plan on getting clomid as well for the post.
