Ill look into the N-Acetyl-L-Tyrosine, but I assume that as a precursor, your body needs to be in a state to actually want to produce more dopamine in order to make a precursor effective? for instance stress would be telling or blocking your body from producing it and the Tyrosine cant overcome that?

Ive wondered about the once a week vs twice a week with the"rush" because if your body is producing naturally (no trt) it can create a surge of hormones with a libido spike when it needs to vs twice a week and steady dosing where it cant spike on demand?
