Winny gives me ance even at low doses... I prefer Masteron. Oddly since I start pretty lean iv found I can get similar effects from Ostarine and 2-3 weeks of insane amounts of cardio and dropping calories to 2500/day avg. Never tried S4 because I have better than 20/20 vision and never wanna mess with that but S4 intrigues me...
Have an AI on hand but not likely that you will use it. Crashing estrogen is much worse than high estrogen, trust me. Better to be safe though. What is your current body fat%?
