The blue razz flavor is better than the peach mango but they both leave a weird chalky after taste in your mouth. They both also have an interesting smell, it's not bad but I may try a different brand before coming back to this.*

I really like this product. I thought the energy part would be "meh", but when I take it I can notice a difference in energy in about 5-10 minutes. This product hits all the 9 essential aminos they tell you that you need. I'd highly recommend this product.*

Love all the flavors so far. A great addition to early morning workouts w/o eating breakfast. I'm not a fan of fasted state training in any way. Two scoops of this plus a carb powder make for a great intra workout.*

Hands down best tasting EAA’s I have tried. I have tried many other brands before, but these are the best. The potency of the flavor is what makes it for me, I mix 2 scoops in a gallon of water so I can drink them all day, and the flavor is not watered down like most other brands. *

Watermelon amazing flavor. Finally found my go-to intra workout drink without needing 2 or 3 different powders. EAA's, BCAA's and Electrolytes all in one. Fantastic product that is a must have for me at the gym. Personally, I use 30 oz shaker, fill up 22 oz water, 1 scoop Rule 1 and top it to the max with ice.*
