I'm on it now- week 1.
From what I see, it messes with your mind. You constantly feel smaller, which is a problem Imo as it claims to improve the neurotransmitter- dopamine (l-dopa); Strength is going up quick.
BIG problem for me: VERY rough on your central nervous system. Make sure you're getting 8hrs of sleep, minimum. The first week is stressful and it's as if you've overreached and became adrenally fatigued.
will update this thread as my cycle goes.
Give it a try, I need other people to take this.
