The love/hate relationship with stimulants sucks. I can only tolerate dmaa, that’s why I have and endless supply. The other shit makes me think about my heart until I can force some food down. But it’s a struggle finding the exact dose to take when my tolerance goes up. Sometimes I feel nothing and sometimes it’s too much. For you guys into crazy stims, my new preworkout will have amp citrate, dmaa, synephine and caffeine. If stimulants aren’t for you, Cardarine is the best. I’ve never seen anything give that type of energy besides strong stimulant like ephedra or dmaa. Its now my best seller for men and women. It just took ostarines place. I don’t take it daily for fat loss or to preserve muscle while on a deficit ect, just as preworkout. I can take 30-35mg at 8pm, train 2 hours, go eat and then sleep no problems at all. I’ve never seen or hear of any side effects on anyone either. The only downside for me, I don’t get the energy burst until I start doing some sort of exercise.
