Are you talking about creatine ethyl ester? Its not monohydrate and it tastes like swallowing cleaning solvent.
When I first tried it a year ago I vomited in my kitchen. Then I began mixing it with teas, and now after a year I can take it straight with even warm water, tho occasionally you can get a little gagging if your mind is not clear.
Tip, position your tongue to have as little contact with the stuff as possible to reduce taste sensation. I concentrate very hard, take a slug, take a breath, take a slug, take a breath, until its gone.
Another tip, mix is with less water so you have to drink less. yes, it will be a higher concentrate, but i think its better to get it over with quickly. Then chug water afterwards to get the right ratio of mixing in your stomach.
