I have a tough request:
Caffeine/stimulant based supps have zero effect on me and I think I have a handle on it. I have the genetic inclination towards ADD. My brother was diagnosed early with ADHD and then my dad was diagnosed with Adult ADD. I don't have any of the tendencies but I have noticed that stimulants do jack squat for me, for example I can drink a double espresso and go to bed.
So, my quest is to find a good supp that works in a non-stimulant fashion. Any recommendations? I'm mainly looking for something for recovery since I've been staying sore longer in my old age.
