^^^^^yea depends what your using it for.
Can be used during a cycle of gear with a higher likeliness to shut you down hard (19-nors) Can also be used before a cycle ends to jump start natural hormone levels. Before PCT. Some argue its not needed intra cycle. In my experience it can make managing estrogen a challenge when used during a cycle. Everyone is different. Also depends what you using. I never had any issue with it then this year all of a sudden it started giving me some gyno issues while on Sust. first time on Sust so I figure it was that.
Pros = signals natural hormone production, increases natural test. Keeps your balls from shrinking.
Cons = Raises estrogen levels as well, can contribute to gyno. Easily over dosed if not careful resulting in decreased sensitivity and response to the natural LH (leutinizing hormone)
