Not too difficult honestly. I know what the other products feel like. I've been running them awhile. With the addition of this oral, I am having a bit of lethargy. This happens to me with most orals that are properly dosed. I also am having a bit of appetite suppression and indigestion which most orals do to me as well...but not nearly as bad as some times. Dbol usually has me crushed in a week. I still feel pretty good on this. The pumps from my workouts have been insane! Like...almost too much. I actually had to pause my arm workout because the bicep pump hurt. I've also noticed some increased vascularity as well. Definitely seems to be a good product
