Might wanna keep that near 400mg if you're running it solo. 600mg used to KILL my estrogen, and weeks into the cycle I would start feeling like total ass.
I think my estrogen is still pretty high. My face still didn't get completely normal after 1st cycle. Total ass in what way?
On my last run I felt 85-95% recovered. To the point where I partied HARD on new years lol.
