Don't bother taking clomid or any anti-e while on an m1t only cycle. They won't stop shutdown or help with any sides. As far as the gains go, as long as you work out, sleep, and eat enough while on, you'll gain both muscle and strength and will keep most of it as long as you do pct. If you're not already at your natural limit, you'll also continue to gain muscle and strength after the cycle. I've done 3 short cycles - 2wks on - 2wks pct - 2 wks off everything. I gained while on and during pct everytime and kept all of my gains. It's been a couple months since the last cycle and I'm still gaining in strength although my total weight is down (muscle mass is the same) because I am cutting at the moment before bulking again.
