Rated 4 out of 5 by from Awesome stuff I finally got to use it in a race. I had a bad bike crash 3 weeks ago, so bad I had to buy a new one. So with little training over these past 3weeks due to injury from that crash, I took the race boost, anti fatigue and enduralytes. I had a pretty good race, only 40 sec slower than last year at the same race. Which I did after ironman CDA..

Rated 5 out of 5 by from Great results. I am impressed! I bought this product two months ago. I ran a half marathon and my time was nine minutes faster than last year. It definitely works miracles and I would definitely recommend. Thank you Hammer Nutrition.!!

Rated 5 out of 5 by from Race PR Kit Used these products before my first 10k rowing event, along with Mito Caps and Race Caps Supreme. I'd never rowed that far before and I actually never felt tired throughout the whole event (53 min.). I did train, sleep and eat properly but I was impressed with how strong I felt.

Rated 5 out of 5 by from Can't Recommend Enough! From a comminuted hip fracture on 12/25/13 to a win on 6/7/14. Hammer products, including this package were a big part of my comeback.

Rated 5 out of 5 by from No BS - It works! It works! I've been taking AFC, RDB, and ES for over six weeks or so now in preparation for the Boston Marathon next month. I am not going to try and feed everyone BS and say these products are a panacea, but I will say this; they work for me without a doubt. As an amateur athlete, I have tried everything...seriously. The PR Race Kit and the Daily Essentials Kit are my mainstays. It is a powerful and legal way to increase and sustain energy, improve performance, and realize gains. I plateaued for several months - as a matter of fact, regressing in some instances and I'm back to improving. I will continue to use the PR Race Kit and Hammer products. I am definitely sold.
