I have been using N2 Slin religiously for at least 8 months now...and I know it has helped me stay lean as I am today. I eat clean for the most part...lean protein, fiborous/complex carb sources, healthy fats...but there are my cheat days where I will have my authentic Carne Asada tacos, pizza, sushi (white rice), burgers, burritos...and N2 Slin has been the supplement that I use to make sure that those carbs are being utilized efficiently! I dose 1-2 caps 30 minutes prior to carb containing meals or cheat meals, and this works!!! This is one supplement that I will never cycle off of...and am currently having my wife take it to help her trim off some holiday eating frenzies!!!
