Have used this doing the Jacked program and definitely have seen improvement in recovery between sets. Both flavors are amazing and no aftertaste. Highly recommended!
Been using training supplements for over 40 years, this one had the most immediate and more importantly lasting impact. Worked first time I used it, still works many months later.
I am getting back to lifting weights again. My friend introduced me to these workouts and this supplement. I have never even taken any kind of supplements before. I did weight lifting with and without supplement to see if it makes any difference and I could tell it REALLY does make a difference and it helped me with quicker recovery and let’s you carry on your workouts without longer rest periods in between sets. Lemonade flavor taste delicious.
I am 59 and I would start running out of gas doing Ultimate Arms program, I bought the PR-X product, 3 months ago, my strength/energy has gone up a lot and I can now handle the weighted pull ups now. Great product because it delivers.
When I was given this “report” of PR-X, I couldn’t answer straight away. The reason was our lovely 2020, I had to stop going to the gym for 6 months and I was trying to exercise at home. But it wasn’t the same. I increased my weight 9kg, making me 106kg.
I started taking PR-X when it first came out. Of course the taste is delicious, but that’s not important here. I believe it has increased my strength but I am more concerned about this weight. From half way through April, I have lost 5.6kg mainly because I have dropped the amount of dinner. All other meals are the same and I get up to exercise at 4am in the morning.
So all of that plus I am 49yrs old now, it is hard to judge PR-X, as there are many variables. Also tomorrow is my last day of MAX-Shred.
Still, I take this religiously. After taking RX-1, I take this to gym. It does make me stronger during the workout. I started weight training at 14yrs old and you do get to know that a lot of products are not worth a bar of soap. Even though Athlean-X products are on the expensive side, plus being approved, I’m commited!
I purchased PR-X Max Strength /Energy. I noticed a difference right away. I felt an increase of energy and since then, I look forward to sipping through my workout. I will definitely purchase again. Atomic Lemonade is my favorite and just purchased 3 more on Monday. Great product with great benefits.
I have been using both the Doctor C’s and the Mechan-X supplements for awhile now and love them, so I was excited when PR-X was launched. I got both flavors to have on hand as I started the new Old School Iron Program. They both taste great! I am using it intraworkout and can really tell a difference in recovery time between sets. I forgot it a few mornings ago and could tell a big difference as I went through the workout. Another thing I like is that it doesn’t give me the jittery feeling that I have gotten from pre-workout supplements. You know if Jeff stamps his name on it that it is going to be top shelf and this one doesn’t disappoint. I have already ordered more! Thanks team Athlean!
I never used intra-workouts before and thought they were all gimmicky, but this one does what it says it does. I sip it between sets and I feel like I am always ready for the next set. I really notice it when I am particularly low on energy that day but still want to train. Drinking this helps me get through it. There’s no crazy caffeine rush or anything like that, just a steady flow of strength and energy to get through the whole session (my sessions are 45-60 min on average).
Using traditional preworkout supplements with high amounts of caffeine and with other typical ingredients is not recommended and can be dangerous for firefighters. We lose a lot of water due to our gear, the extreme heat, and because of the amount of work we need to put out during a call.
PR-X is well suited to provide sustained energy without the jitters and diuretic effects of other products. It helped me to be my best even in the toughest of situations. I have PR-X always ready to go.
If you are looking to take your strength to all new heights and push your muscular potential to its natural limits, then PR-X is the right supplement for you. Designed to specifically target the phosphagenic energy system (responsible for most all heavy training that occurs in the 1-8 rep range), PR-X will help you increase not only the strength you have on all of your lifts but recover from each heavy set more fully and at a much faster pace. This groundbreaking new intraworkout supplement is perfect for any seasoned lifter that has found themselves struggling to make strength gains and longs for the “early days” when adding plates to the bar seemed to happen with each new workout. It’s time to bust through your strength plateaus and hit all new PR’s with PR-X. Training hard has never felt this easy.
After listening to the wants and needs of our athletes, we developed a supplement that is designed to do one thing and one thing only - keep you feeling stronger…for longer. This could not be done without the rigorous testing and research ATHLEAN-Rx is known for to include the highest quality and safest ingredients available…formulated to deliver quick and noticeable results. Focusing on both the increasing ATP production in the fast acting phosphagen energy system and speeding up the recovery inducing glycolytic aerobic energy system for fast ATP replenishment between sets, PR-X provides the potent one-two combination necessary to take intraworkout supplementation to all new heights, and your performance along with it.
PR-X uses not only the most effective and safest ingredients on the market, but is clinically dosed to make sure that you are never shortchanged in what you purchase. Other supplements often contain fillers that do nothing for the efficacy of the formula while at ATHLEAN-X, we avoid such fillers to make sure that you are getting exactly what you paid for. PR-X ingredients include L-Citrulline Malate, Kre-Alkalyn® Creatine Monohydrate, CoEnzyme Q10, NADH, and D-Ribose; all of which, when dosed together as in PR-X, are designed to deliver unparalleled results.
As with all of our supplements, PR-X is proudly produced in the United States to the highest industry standards. Our commitment to transparency and quality has our RX supplement lineup trusted by many of the top teams and athletes in professional sports where rigid drug testing practices are the norm.
If you find yourself feeling fatigued during a heavy training session (either too tired to lift what you know you’re capable of or excessively worn out after each set, requiring extra time to recover with each subsequent set) and know that your compromised effort is holding back your gains, then PR-X is exactly what you need. When taken during your workout, PR-X will ensure you leave no gains on the table and help you to maximize your performance in every workout to reach all new levels of strength and size. Get ready to attack each set of your workout without compromise. PR-X is going to change the way you train forever.
"We’ve all had times when we feel fresh and ready to attack the weights at the start of a workout, only to be left feeling drained and discouraged by our overall effort at the end. With PR-X, how you start is how you’ll finish. Strong. I’ve always felt the ability to consistently string together high effort workouts, uncompromised by fatigue, is the true differentiator between the good and the great. It's time to unleash the greatness that’s been in you all along.“

Reduces the sensation of fatigue and increases the rate of ATP replenishment following intense exercise.
A buffered form of creatine that is processed at a higher PH level allowing for better absorption, smaller dosages and less bloat.
Serving as the backbone of ATP production, this crucial sugar ensures you stave off fatigue and prevent energy depletion during training.
Amplifies effects of NADH to stimulate greater ATP production, increasing exercise time to exhaustion while delaying lactic acid buildup.
The body’s most important co-enzyme for repeatedly and efficiently generating energy producing ATP to fuel muscle performance longer.
For increased energy and quick recovery between sets, mix 1 scoop of PR-X with 8-12 oz of water and sip it throughout your training session. PR-X can also be taken as a stand alone caffeine-free preworkout option (mixed as above and taken 15 minutes prior to training) or taken alongside your RX-1 for an incredibly powerful performance enhancing combination. It is advised that you mix each separately however since the taste may be adversely effected when combined (then again, it could be amazing but we don't want to be responsible for your taste buds!)
PR-X is designed for the serious trainee looking to reach new levels of muscle growth through increases in untapped strength. Powerlifters, Olympic Weightlifters, and other strength athletes as well as anyone looking to reap uncompromised results from their hard training will all see significant benefits…pushing the envelope of their strength, power and intra-workout recovery with PR-X.
PR-X is best taken as an intra-workout supplement, mixed in water and sipped throughout your training session. What you’ll notice is that the high effort sets that used to leave you drained for the rest of your workout will now be much easier to recover fully from with PR-X, and rest times between sets will be shorter. Less rest between sets means you’ll be in and out of the gym quicker without compromising your training to do so.
RX1 is the preeminent pre-workout designed to fuel all three energy pathways to deliver jitter free focus and energy for all types of training. Though safely dosed, it does still contain caffeine as one of the drivers of these benefits. PR-X on the other hand is caffeine-free and specifically designed for dramatically boosting the strength reliant phosphagen energy system and quickly replenishing it throughout your workout so you can train stronger for longer and push the limits of your potential.
PR-X and RX-1 were carefully formulated to allow them to be taken together without exceeding dosage for any of the results-proven ingredients included in either product. Of particular concern for many, there is no caffeine in PR-X, freely allowing you to stack the two without ever going over the 200mg caffeine threshold deemed maximally effective and safe by the NSF Cert for Sport program (followed by today’s top pro athletes). Citrulline malate and buffered creatine (common to both), bring them to the highest ranges of clinically effective dosing without compromising the safety of either.
With its ability to deliver significant increases in strength and energy, PR-X can serve as an effective pre-workout supplement - particularly for those that prefer to reap these benefits without having to supplement with a caffeinated pre-workout to do so.
Not only is the amount of sugar contained in PR-X much less than what you’d find in many popular energy drinks and pre-workout supplements but, here as always, the type of sugar matters. All 8 grams in PR-X come from D-ribose, a simple sugar found naturally in our bodies. Unlike other sugars like table sugar (sucrose), corn sugar (glucose) or milk sugar (lactose), which can uncontrollably spike blood sugar levels, D-ribose with its negative glycemic index can actually lower them and is instead used exclusively to form the backbone of ATP - the key energy molecule that fuels all muscle contraction and performance.
PR-X promotes muscle growth in three distinct ways. First, the increases in max strength and repeatable strength will provide a direct stimulus for muscle hypertrophy though increased muscle tension overload. Second, the inclusion of creatine (a research proven driver of strength) will directly assist you in your pursuit of this new strength. Finally, the citrulline malate and NADH/Co-Q10 combo will promote faster muscle recovery between training sessions to keep you training at your hardest every time you touch the iron.
While none of the ingredients in PR-X were included directly for their fat loss benefits, the increases in aerobic glycolytic endurance from the citrulline malate and NADH/Co-Q10 combo will allow you to train longer at a higher level of effort. As always, fat loss comes down to calories in vs. calories out. The more work you are able to accomplish, via a higher effort and longer duration, the more calories you will burn which in the end will assist you in your fat loss goals.
There are 22 servings in each bottle of PR-X. With most dedicated trainees working out 5-6 days a week, this factors out to be enough servings to fuel your workouts for an entire month of training.
While PR-X is primarily geared towards maximizing strength for training and performance, its effects span much wider due to its ability to fuel the oxidative aerobic energy pathway as well. In fact, two of the ingredients in PR-X (when given in combination) have been used effectively to help manage and treat symptoms of chronic fatigue syndrome. So if you’re looking for an overall increase in energy levels and prefer to stay away from caffeine or other stimulants to achieve this, PR-X is an attractive alternative.
