In a 12 Week Published Double-Blind Study conducted at the Univ of Tampa, our patented main active ATP ingredient was proven to:

¤ Increase Lean Muscle 2 Times MORE EFFECTIVELY than the placebo.

¤ Increase Squat 3.15 Times MORE EFFECTIVELY than the placebo.

¤ Increase Bench Press 1.7 Times MORE EFFECTIVELY than the placebo.

¤ Increase Deadlift 2.38 Times MORE EFFECTIVELY than the placebo.


In 2015, an in-house study with highly trained functional fitness athletes proved how effective ATP Extreme is at increasing high intensity endurance…

1 DOSE of ATP Extreme INCREASED TOTAL REPS by a WHOPPING 17.9% for a GRUELING 5 Round High Intensity Interval Workout.

In addition, it was noted that the performance increase was much more significant during the later stages of the test workout where lactic acid fatigue is normally a major factor.

The number one benefit I get from ATP Extreme is the reduced lactic acid, and that is really huge for a crossfit athlete because it allows me to do more reps and sets, increasing my training volume. I’ve also noticed that my recovery between training sessions in much better and I’ve been hitting a lot of PR’s in my strength exercises. The performance gains I have experienced have been significant, and I truly believe that any athlete that trains at high intensity will benefit greatly from ATP Extreme. *

ATP Extreme has truly taken my training to the next level. My pumps have been through the roof, my vascularity has been crazy and my training capacity off the charts. Since being on it, I’ve been training like an animal – like hitting 315 on bench for 20 reps (something I had never come close to in the past), and my muscle soreness is way down as well. I can’t say enough good things about this product. Anyone who wants to train harder, build muscle faster and get shredded needs to try this product! *

I have been taking ATP Extreme for almost 2 years now and I can say without a doubt that these have been the most productive years of my entire career. I am training harder than ever, my body is recovering faster than ever, and I am finishing my races stronger than ever, all of which has helped me run sub 10 seconds almost every time I step on the track for a 100m race. The way ATP Extreme helps with lactic acid is incredible. If you are a high performance athlete, you need to be taking it if you want to maximize your potential as an athlete! *

After just 30 days on ATP Extreme my 405lb back squat went from 6 reps to 10 reps, which is a 60% rep increase. That’s huge. I also noticed that my recovery times are much faster and my endurance is way up due to less lactic acid. Now my training volume is way up, but I still feel fresh coming into every workout. ATP Extreme has been very beneficial to me as a crossfit athlete because it truly does affect all aspect of my performance. *

ATP Extreme has been great for me as an endurance athlete. The vasodilation effect helps me sustain high power outputs for longer periods of time, it helps with my recovery, and it helps me sustain intensity during my workouts. Since ATP Extreme allows me to train for longer at 80% of my maximum threshold, I know that it is also helping me increase my VO2 max. I can definitely say with confidence that ATP Extreme has made me a faster, more powerful athlete. *

ATP Extreme is an extremely effective ergogenic aid for the gym. I’ve been using it for over a year now and since being on it, I get much better pumps, my strength levels have increased, and my endurance is way up. I recommend it to all my clients and virtually all of them get the same results I have been getting. This is a fantastic product, I highly endorse it, and I will not workout without it! *

I’ve had an awesome experience with ATP Extreme. The first time I used it was in competition. It was the 4th consecutive day of racing for me and we raced 80 miles through rolling terrain. My legs were really tired and sore coming into the race and I was not expecting to perform very well. I ended up doing way better than I expected and since then have started using it consistently in training as well. It basically reduces my rate of fatigue, increases my energy and endurance, stabilizes my heart rate, helps me sustain high power for longer, and helps me perform much better in the hills. It also reduces my recovery times, which is extremely valuable when I have to race on consecutive days. This is an amazing product and I recommend it highly to all my fellow cyclists! *

ATP Extreme has really helped me deal with lactic acid and reduce my recovery times. I started using it mid way through the 2013 season and immediately noticed how much better my body was able to handle the high intensity training required as a 400m sprinter. Since each batch is Certified Drug Free, I can use it with confidence under USADA and I’m excited to see how long-term, consistent use of ATP Extreme will help me on my quest for a 2016 Olympic Medal! *

I was really burnt out after the 2013 Crossfit Games, and that’s when I found ATP Extreme. As soon as I started taking it, my training was completely reinvigorated. My energy was way up, my recovery was awesome, my strength started going through the roof and I was hitting PR after PR after PR. This product is truly a GAME-CHANGER. Everyone in my gym smart enough to try it has gotten the same amazing results I have. It allows you to train harder and longer, and helps you maximize the results from your training. To get all these amazing performance benefits without any adverse side effects is awesome! *

ATP Extreme has really taken my training to the next level. My pumps are outrageous, my vascularity is more pronounced than ever, my endurance is SIGNIFICANTLY better, and my strength has been increasing at a faster rate than ever before. In some cases I was able to double or even triple my reps to failure after just a month or so on the product, which is absolutely crazy! I have also found ATP Extreme to help me get more out of my other supplements, especially my carb-based pre-workouts. In my opinion, anyone serious about building a better physique, needs to be taking this product. The fact that it is all-natural and free of added stimulants is just a bonus. *

When I first started taking ATP Extreme, I immediately noticed how much harder I was able to push my body. This enabled me to program harder and harder workouts, but I kept completing them without any problems and my body still felt good because my recovery was so awesome. Fortunately for me, I found ATP Extreme several months before this year’s Crossfit Open and it played a really big part in me qualifying for SoCal Regionals and eventually finishing 7th. Thanks for making such a great product. It really does affect all aspects of performance and help you get faster results from training. *

Before I started taking ATP Extreme I had reached a plateau and I was looking for something to help me bust through it. As soon as I started taking it, I noticed the difference right away. My endurance went through the roof, my muscle pumps improved dramatically, my lactic acid went way down and my strength gains were unbelievable. For example, within just 2 weeks on the product, I was able to more-than-double my reps of 315 lbs on bench press, which is insane… and these types of gains came across the board on all different exercises for me. As a Natural Bodybuilder, I am very careful about what I put into my body. With ATP Extreme being all-natural and stimulant-free, I get all the benefits I want without having to worry about any long-term side effects. That’s important to me. *
