I'll gladly modify this list as others chime in :head:
6-oxo
Pros:
-good estrogen control
-enhanced libido
Cons:
-must be dosed high (price)
-can be rough on the joints
Controversy:
-none that I'm aware of
ATD
Pros:
-price
-strong estrogen control (can also be a negative depending on the situation)
Cons:
-libido killer
-rough on the joints
Controversy:
-I've heard of estrogen conversion but haven't seen concrete evidence
-I believe I've seen estrogen rebound after abruptly stopping this AI (which shouldn't be an issues since it's supposedly a suicide inhibitor)
Formestane:
Pros:
-strongest estrogen control (otc)
-cost effective if used transdermally
-decreased local chest fat
-significantly enhances libido
-joint issues not commonly reported (with the exception of stacks with very dry compounds)
-raises IGF
Cons:
-4OHT prohormone (which may be a pro depending on the situation)
-frequent issues with transdermal crashing out of solution
Controversy:
-although unlikely, it's possibly suppressive
6-brom
Pros:
-effective estrogen control
-libido enhancer
Cons:
-price when dosed appropriately
Controversy:
-although unlikely to be suppressive, there is potential for anabolic isomers
