The protein that you look forward to drinking.

At 51 years old, and being someone that has been buying protein powders for over 30 years, I thought I had already tried the best proteins available.
I saw the Black Friday sale and decided to try something new since the price was really good. I was not expecting it to be as good as it is. I had only tried one of the included samples that they threw in my box when I knew that I needed to buy more and stock up. The 6 tubs should get me through to the next sale...although my girlfriend is now hooked on it after trying my pistachio flavor. I haven't tried them all yet but pistachio is amazing! The chocolate fudge is also amazing. Can't wait to try my mint chocolate chip and café mocha. I am betting the banana will be great as well. I am hooked! Can't see my myself buying anything else now.

Some of the nicest packaging on a Tub I have seen! RULE 1 definitely has pride in their products, I just started using their protein. The mocha taste is superb! Makes me feel as if I’m drinking a Star*ucks/McDs Frappe with 3x less calories and 10x protein if not more (Double scoop)! I will update my review after a month of usage. Look forward to the next shake and results!
