Having been in the fitness industry for a number of years now, I've sampled and tried dozens of different supplement products. I started taking NutraKey products a few weeks ago and the experience has already been tremendous! The Chocolate Lava Cake Whey Optima Protein is one of the best-tasting I've had and works perfectly for baking purposes. I've definitely noticed a difference in my nightly protein waffles! I've also been taking the BCAA's which are great in assisting with recovery, particularly after an extra taxing workout that leaves me incredibly sore. The L-Carnitine has been awesome as well. Love the Green Apple Pucker flavor and have started seeing a difference in my lean muscle tone. I'll never claim that supplements are required to see results but they definitely assist in the process and NutraKey has a great selection.
