I have never done this (I co-own AtLarge Nutrition), but I wanted to take a quick second and mention that we have our best selling ergogen RESULTS on sale right now. RESULTS is a combination of Creapure creatine monohydrate, Beta-Alanin, HMB, and dextrose all at lab proven doses. It is a VERY potent strength and strength endurance supplement which is perfect for CrossFitters. The only catch is for Paleo practitioners relative to the dextrose and to that I only can say I strongly suggest you consider giving it a try.
I have personally worked with many CrossFitters who have given this product a try and found it to be very effective. The sale is 20% off (from $49.95 to $39.95 for a 30 day supply) and lasts until Wednesday 10/20. Here is a link to the product if you are interested:
