AE2 from Nutrabolics:

Produces Explosive Muscle Growth Within Muscle Tissue!

Generating a groundbreaking buzz from the day it's been introduced, AE2 is the first Arginine Ethyl Ester product ever to be released into the supplement industry. With a beyond potent combination of two drug-like arginines, AE2 will equal or surpass the ability of any prohormone or nitric oxide booster to produce explosive muscle growth within muscle tissue. AE2 contains new biochemical Ethyl-Ester technology (Arginine Ester Technology) stacked with the ultra potent nitric-oxide-releasing-compound, Arginine Alpha Ketoglutarate. By combining these two radical forms of arginine, the ability for arginine to be fully absorbed into the bloodstream, transported to muscle tissue, and absorbed inside muscle cells has, for the first time ever, reached close to 100% efficiency.

The mix of these two Arginines is the secret to AE2's proprietary formulas success. Nutrabolics has assembled an all-star team in research, chemistry, nutrition, manufacturing and quality-control to bring this new compound to the market; AE2 is a classic case of real science and innovation working together for unsurpassed results! AE2 is the new protocol for any athlete interested in achieving a hard, lean physique or for those that have been predictably disappointed by the hype promised by inferior Nitric Oxide products.
If you got a "pump" from any old NO product, you are in for a skin-bursting experience with AE2!
