The Last Pre-Workout

You'll Ever Need!

Have you been finding yourself changing pre-workouts every few weeks? Are you satisfied the first 1-2 times you use a new one, but by the end of the tub you find yourself chasing that initial feeling you haven’t felt in weeks? You are not alone. In fact, that was the #1 complaint by all pre-workout users we questioned over the past year.

With all of the pre-workouts out there simply trying to put a new spin on stimulants, how many of them actually contain ingredients that can contribute to the workout you are about to give all of your effort to? If you are a dedicated athlete you know that you have to spend hours in the gym week in and week out for incremental gains over time. So why shouldn’t the product dedicated solely to enhancing your workout have the same mindset? What good is a blend of stimulants with zero ingredients for the long term approach of bodybuilding and training?

Prolific has a unique formula based on cognitive, performance-driven, pump-packed, and energizing components to deliver a newfound experience that never gets dull.* This specific formula is centered around the most underrated phenomenon during your training: The Mind Muscle Connection. Prolific cares about every rep of every workout from beginning to end, because we know that is what truly matters for your goals.

The Mind Muscle


Have you ever showed up to the gym feeling great, thinking it was going to be another solid day of lifting, but instead for some reason you just have a terrible workout? You feel disconnected, suddenly unfocused, and beyond frustrated by the end of your session. It sounds like you had some serious mind muscle disconnection.

This special connection is what you are focused on in every rep you take. Feeling the firing of muscle fibers, and the powerful contraction during each rep. Supercharging this mechanism will give you an all new workout experience. Feel the power in each rep, the dominating contraction, and enjoy the lasting pump after every set.

We have developed a special formula to create the ultimate foundation for getting your mind and body working in harmony as the ultimate powerhouse.*

More of What You Need. None of What You Don’t

In typical PEScience fashion, we have delivered a formula that goes above and beyond. Each 2-scoop serving of Prolific contains 6 grams of L-Citrulline, the citrulline equivalence of 12 grams citrulline malate. 6 grams is far above the pump and endurance know no boundaries with Prolific.*

We have a novel blend of caffeine using both caffeine anhydrous and Infinergy™ (dicaffeine malate), coupled with theanine for explosive energy.

We have also left out all of the mundane ingredients you find in traditional copycat pre-workouts all over the market today, like creatine and beta-alanine. It still blows our minds that these ingredients are used in pre-workouts, considering all of their scientific data is based on continuous use over time, not an acute effect after one dose.* Unfortunately just because your skin is tingling doesn’t mean your workout will be better.

A New Take on Pre-Workouts

Today the pre-workout market sits in disarray. On one end of the spectrum you have products that contain nothing but a cocktail of stimulants, which is great for mental energy but lack any support for muscular performance or long term results, and they lose their effectiveness after just a few uses. On the other end of the spectrum you have pre-workouts in big tubs with tons of ingredients...most of which have nothing to do with enhancing your performance before a workout, and need to be taken every day to be effective, not just on workout days.

There’s still dozens of products on the market using non-compliant stimulants. But take a moment to think about that for a second. If a company is willing to cut corners and use non-compliant ingredients, what other important quality control steps are being skipped in the formulation and production of the products? To read more about our quality control processes, check out the PEScience Difference.

Prolific is designed with each and every workout in mind, and maximizing your full potential in the gym. What is the point of a pre-workout if it isn’t designed to maximize your full potential in the gym for every workout?

Your workouts need a new, superior experience. It’s time to up your game. It’s time to be Prolific.

Q and A:

What is the difference between Prolific and Alphamine?

Alphamine is designed solely for energy and thermogenesis. If you are looking for the absolute best value for a clean burning, energizing, thermogenic powder that can be used anytime, anywhere, then Alphamine is your go-to. Prolific is designed specifically for pre-workout use, and has ergogens, cognitive ingredients and pump producers that Alphamine does not contain.

What is the difference between Prolific and High Volume?

Both Prolific and High Volume will produce powerful pumps like you’ve never before felt. High Volume does not contain any caffeine, stimulants, or cognitive compounds. It is purely a pump and performance product.* It is the go-to for those looking to avoid stimulants entirely, or those looking to customize a pre-workout stack. Prolific already contains two forms of caffeine, plus innovative cognitive compounds, making it an all-in-one pre-workout stack in a bottle.

What is the difference between Citrulline and Citrulline Malate?

Many people use these two synonymously, but that is incorrect. Citrulline malate is what the majority of pre-workouts cost. The raw material itself is only 50% citrulline, and 50% malate. Malate is a very cheap ingredient typically used for flavoring purposes that has zero effect on pump or nitric oxide. Citrulline is what makes all the magic happen. That is why our 6 grams of Citrulline per 2 scoops of Prolific has the same citrulline equivalent as 12 grams of citrulline malate.

How much Prolific should I use?

We recommend everyone starts with just one scoop. You need to first find out your tolerance to the caffeine and formula as a whole. Many of the ingredients in 1 scoop of Prolific are the same amounts seen in 2 scoops of other products, so 1 may be all you need.

Why does this product leave out ingredients that many run-of-the-mill pre-workouts contain, like creatine, beta-alanine, and yohimbine?

Creatine and beta-alanine are not pre-workout ingredients. Manufacturers add them to pre-workout products because they are easily recognizable ingredients, and it helps customers think they are getting a good product. Unless you are taking your pre-workout every single day (which you hopefully are not doing) then you are not getting all the benefits and claims that these ingredients bring along with them. That is why we created Ergonine. It has all the ingredients that should be taken on a daily basis, and that have no use for acute performance increases before a single workout.

When we asked pre-workout users what their top complaints were with previous products they have used in the past year, the #1 answer was how fast the product lost its effectiveness. This is caused by tolerance building extremely fast to stimulants such as yohimbine (yohimbe). Our formula is built around sustainability and a feeling that doesn’t become dull.

Its very good product when you need energy. But down side is that i take it after work and i do work out in the night time that sometime makes me unable to full a sleep fast. But over all it gets the job done and i love it

This pre-workout tastes so good! I feel like I get better workouts done when I take it because of the focus and energy it gives me. I also feel more of a steady energy and don't crash afterwards. Will definitely be purchasing again :)

Absolutely love this product! Gives a good kick and pump, excellent for early morning sessions and no coffee is needed as it contains caffeine. My favourite flavour is melon berry twist and I also got High Volume in this flavour and stack them together on occasion. Mango Splash flavour is ok, but not as good as Melon Berry Twist. No side effects noticed.

I LOVEEE this preworkout! No jitters, no itch! I just wish bodybuilding would get the “kiwi lime” flavor! It’s the best!!!!

May 25, 2018

I was fortunate enough to try a sample of this stuff and it certainly delivered. I see myself purchasing a tub in the near future for my next pre for sure. I felt really energetic and focused throughout the whole workout. It also did not cause me to crash later in the day, which some pre workouts have a tendency to do. As usually, PES put out a quality product.

Love the cotton candy!

Oct 18, 2017

This is a very consistent product, aside from the benefits it gives you in the gym, it also can provide those of you who are students as well. It was essential components that are not present in other pre-workouts, such as: Cognizin, Rhodiola Rosea, and L-Theanine. This is a knockout combination for a nootropic, it also contains 160 mg of caffeine which is heavy if you are sensitive to caffeine, but if not it is a good dosage. I recommend this product for both the gym, and as a daily supplement for a brain boost!

I was pretty disappointed in the flavor profile of this preworkout. I was really excited to try the cotton candy but it didn't meet expectations. It is a fine preworkout and does what it needs to do but I will be switching back to C4 after this.

I received 2 sample packs of the Raspberry Lemonade to try out so this review is from just one workout which honestly I wish I had a few more samples to really try it out at least one more time but this is what I think after using both samples for an arm/abs workout. The ingredient profile is disclosed so you know exactly what's in it and on paper it looks pretty good and it doesn't have a bunch of fluff ingredients that you don't need in a PW but it looked like it was missing maybe something in the energy/focus dept. The powder mixed up very well with virtually no foam or sediment, the raspberry lemonade is delicious and you get a lightly sweet lemonade flavor and the raspberry flavor keeps it from being too tart. This co. dose one of the better raspberry lemonade flavors on the market. The energy though it claims to be explosive on the label really hits very smooth and tamed and the focus is not laser but decent enough to keep you at the task at hand which is hitting whatever body part your training. The pumps with the added 6 gm of pure Citrulline at the 2 serving dose is EXCELLENT and there is no need to add any other pump ingredients. I like to rotate my PW each and every training session so for me this would be an ideal PW for arm day or maybe shoulders but it just didn't have that hard hitting energy or focus that you might need for a big body part workout like back or legs. Not a bad PW in any way and if your sensitive to caffeine or heavy stimulants I don't think you'll have any issue with this PW. If your very tolerant to caffeine and other stimulants you might wanna look at a stronger PW with heavier stimulants in the profile. Overall rating 8.4/10 After trying a few more workouts with the Sunrise flavor which is a combo of Orange.Pineapple, and a hint of banana I've upped my overall rating to a solid 9/10 cause this pre-workout delivers not only clean sustained energy and very good pumps it also puts you in a focus zone that has you really concentrating on the task at hand which is getting the best out of your workout. This kind of focus is missing from a lot of these new fully dosed open label other pre-workouts but PES really delivered on this one especially with the CDP at 250mg when you use 2 scoops. I HIGHLY recommend giving this PW a try if energy,focus,and pumps are what your looking for in a PW.

Amazing pre-workout with no crash or jitters!

May 25, 2017

I LOVE this product! It gives such an amazing focus and energy for my lifts. The pump is great as well- but it's even better if you do 1 scoop with 1-2 scoops of high volume! Perfect caffeine amount for me and I always have the best mental clarity in my lifts when I take Prolific without any crashes. Taste is perfection!

So I mentioned interest in this, and good bro kbayne gave me a hook-up! Huge shout out to him for being awesome; this had me wanting to try it, but it isn’t too cheap, definitely has a profile to back the cost no doubt, but before snagging a full tub I wanted to sample some. Well, that was pointless, because now I NEED IT! Well played kbayne, well played. Profile- Well this is most definitely a one scoop is one scoop pre-w/o (well, 2 scoops technically is one serving, but whatever). Ringing in at 320mg caffeine with 6g of Citrulline, 2.5g Beta Alanine, 1.5g Taurine, and 200mg Theanine with a few other ingredients PES isn’t playing here. You are getting what you pay for, and that is a no BS profile and nothing hidden behind a prop blend; like a cheap prostitute they lay it all out to show! [B]Profile- 9/10[/B] Smell- A nice and sweet scent that really does remind me of the cotton candy you can buy in the bags by check stands; really nails down a good first impression! [B]Smell- 8/10[/B] Mixability- Wasn’t too sure how this would mix, given how some ingredients just don’t dissolve. Turns out this mixed without so much as a single issue and no clumping or settling. Very nice! [B]Mixability- 9/10[/B] Taste- Didn’t quite taste like cotton candy to me, more of just a generic sweet candy-like flavor; very enjoyable none the less if you like a sweeter taste. If you do not enjoy sweet tastes though, you will want to either grab another flavor or water this down more; I found 2 scoops to be quite delicious in 12oz of water. [B]Taste- 7/10[/B] Effectiveness- Wow. This may very well be one of, if not the best, pre-workout I have ever had. Dosed at 2 scoops (one serving) was all I needed, the energy is smooth and builds up nicely, giving you a strong awake and powerful feeling but no jitters at all or crash at the end. The focus is like a **** laser, you get locked in and just want to keep crushing it; nothing can distract you while lifting, it is just you and the iron. It also provided (for me anyways) a ‘feel good’ synergy that just makes my routine so much more enjoyable, just a solid ‘happy place’ type of feel that I did not expect.The pump, very solid but just a little bit more would be my preference, this is my only criticism… just a little more pump! This may very well be the closest 10/10 pre-workout I have had, stacking this with a little Big No1se or Hemavol, or another pump product and it is a combo that cannot be beat; worth every **** cent it costs. [B]Effectiveness- 9.5/10[/B] Overall- While the price had me a bit hesitant at first, I would say it is really worth it because in the end there is nothing like it IMO. Some come close, very close, but this was magic to me. I am having a hard time thinking of anything short of DMAA that hits me like this, but I can’t. The focus, feel good aspect, energy, pump… this is just great. Buy it. Try it. Love it.

Overall a solid pre.....good mind muscle connection and no crash/no jitters. The pure cit is great but needs a little stronger pump formula.
