Sometimes what you hear & read is a little different from actuality. I have read that taurine is an osmotic agent for muscle cells - bringing fluid into the muscle cells. I know that glycerine is one too - but I did not like the results from my last try with it.
This time around I'll be re-introducing carbs back into my diet 3 days before my contest. Currently on CKD and will do my last re-feed this Friday. Next Thursday I'll add 30-35g low glycemic carbs per meal every 3 hours. That will give me aprox 200g of carbs per day.
I used to do big-time carb &/or shit-loading. Never came in like I needed to. This time trying something more conservative.
