inderall 40mg. (cardenol). Main ingredient -> propranolol. I now take one a day every day or every other day. Sometimes I take a week break. When presenting I was taking 2-3. Aniracetam you might wanna try too as a cheer up supplement. Also don't push yourself to the limits. Challenges are like weights in bodybuilding. If you start with too heavy weights, it will just strain your muscles leaving you with muscle pain for the next week. Similarly with everything.
