Great Flavor

Wild berry is fire! All the flavors are pretty good which for me is hard to do with other brands

My Go-To

I love this product. Cotton Candy flavor is my favorite but there are so many great flavors. They mix well and don’t give you a jittery feeling from the energy/caffeine in them.

For about 3 years now I have been drinking amino energy about 4 or 5 days per week either as a morning coffee replacement or as a preworkout drink. The taste is great and the energy is very smooth.
