Where did you guys get caffeine powder?

I got the B3 and caffeine to dissolve completely, but not the salicylic acid. Well, it dissolves in warm ethanol, but precipitates when chilled.
Maybe the water I added was a little too cold, but doesn't Haidut's stay dissolved? Not only that, it's a different color. (Maybe because that bottle is super old?)
I wonder if he is still using magnesium acetylsalicylate. That would make it more water soluble. (Though it should still break down into salicylic acid anyway...)
I would ask him how he gets the SA to stay dissolved, but that seems dishonorable.

has anyone considered using thymol, menthol or camphor crystals to add a cooling effect?
