Doc,i wouldn't use eph' to stop catabolism after a cycle.Now clen' is the way to go.I start of on 2 a day and work my way up to my tolerance level,usually 7 or 8.Helps keep strength up,build a little muscle tissue and burn a little bf at the same time.All in all,good shit.Some guys will start to use clen' 2-3 weeks before their cycle ends also.
