I'm Impressed!
I've always been a "No supplements, except protein" type of athlete. But, being an older athlete with an extremely full work schedule, little sleep, and a need to get a workout in, I started researching. I found "Crazy Mass", and after reading thoroughly I gave it a try. The Endurance Stack is what I wanted to try, since keeping my running up to par was most important at the time. No lie...I felt a difference on the first day! As I progressed through my six weeks of using this stack, every few days I noticed better body healing & recovery, my stamina increased, and I kept increasing in muscle mass. I was and still am truly impressed! My next move was to go for the Ultimate Stack, which I've used for about two weeks, now. That got me even more muscle mass. **Here's a big deal**: I DON'T EVEN WORKOUT RIGOROUSLY, AND I STILL GET THESE TYPES OF RESULTS, WITH A HEALTHY DIET! I'm Impressed!

From a Runner
I am a runner who plays Ultimate Frisbee, which involves a lot of intense hard running. To get into shape, I spend a lot of time on the track doing hard sprints and medium distances. I had very positive results. This did not turn me into a super athlete as I felt mostly the same during workouts. However, it was how I felt following the workouts that was VERY different. My recovery time was greatly shortened to the point where I simply needed a short break before doing more. Where in the past I would have been too tired continue, I can now do a lot more which I find to be truly amazing. And it is the ability to do a lot more without wearing down that is allowing me to vastly improve my conditioning. There was another benefit that surprised me. I had been suffering from patellar tendinitis for years, and after just 2 weeks of using this product all knee pain disappeared. The lack of knee pain allows me to run multiple days in a row, something I have not been able to do for at least 5 years. And lastly, another strange benefit is that I no longer need caffeine in the morning to wake up. Instead of drinking coffee to wake up, I take this product, which allows me to feel much more alert and focused than I could before. The only negative that I have experienced thus far is that taking this product after about 6pm can sometimes cause me to have insomnia. I sometimes have a hard time sleeping because I am just amped up too much and cannot settle down. So, I try to limit consumption too late in the day.

I've only been using the stacker for about 2 weeks, and have had quite a noticeable increase with my cardio output in my training. looking forward to seeing how much I improve even more over the coming weeks.
