How to mix Biotest L-Leucine:
1) Add about 8 ounces hot water (preferably it is hot, but this is not mandatory) to a shaker bottle, Mason jar, or other container capable of being used for shaking
2) Add one scoop of the L-Leucine powder
3) Shake for at least about 15 seconds
Ready to drink.
Not impossible to mix.
(Note, if you use cold water, there will just be a little more than doesn't dissolve but will still drink down fine.)
