Sort of Slow...
Really does not perform as well as my previous brand which was very sharp and very quick. This one is a little too slow and a little too blunt. It seems to mix well with caffeine (for example) which isn't really a bonus but ultimately a necessity!
This tyrosine powder isnt ground as fine as others Ive used. After mixing
it with water, part still remains undissolved in the bottom of the cup.
