It a bit sour I like it though. Take it one or 2 per morning. And it really affects my mood. I star feeling effect after 3-4 days. Also it nice to combine with 5htp, which I take in the evening. It’s the best thing I tried for mad mood or different supplements hangovers

Dopamine Support

This is the ultimate clean support for dopamine. Caffeine has too many side effects - a single dose of N-Acetyl L-Tyrosine seems to be the purest method for natural energy.

I wanna like this. It's got all of the precursors and it's a smallish pill, but I wish it was a capsule because I find the hard edges hard to swallow... It's just hard to assess right now when I'm stressed. It worked some days but not consistently and it could be a completely different reason other than this being effective/ineffective.

seems like it's stronger than the free form and also doesn't give that much headache in comparison to the free form of tyrosine
