Product Overview Signature Pre-Workout

A good pre-workout is much more than a megadose of stimulants: It’s an essential tool for making the most of your training time. Signature Pre-Workout includes proven ingredients that promote intense pumps and growth while battling fatigue, so you can work out harder and longer.* Signature Pre-Workout tub


One of the keys to a great workout is a great pump. The amino acid L-Citrulline contributes to your body’s production of nitric oxide, a vasodilator. When your blood vessels are dilated, your body is better able to circulate oxygen and other performance-maximizing nutrients to working muscles.*


The amino acid L-Leucine is known as a trigger for muscle protein synthesis (aka muscle growth) and a fuel source for your hard-lifting muscles. Your body cannot make L-Leucine, so it must come from supplements or food.*

Carnosyn® Beta-Alanine

Beta-alanine acts as a buffer between fatigue-promoting lactic acid and your muscles by producing carnosine, which keeps lactic acid in check during intense workouts. That means better muscular endurance, more energy for high-intensity or explosive movements, and better overall workout performance.*


Caffeine is one of the most common pre-workout ingredients because it works. Supplementing with caffeine has been shown to increase focus and improve workout performance, allowing you to dig in and get the work done.*

A signature is a promise. A symbol of your identity. Your mark on the world. In 1999, was founded on a single promise: Trust. It’s who we are and it’s in our blood. Our Signature line is built on the same promise. Every product is no-BS, transparent, filler-free, and formulated with effective doses of research-backed ingredients you can trust. We create the highest quality supplements, so you can focus on leaving a mark of your own.


Signature products are formulated with high quality ingredients at effective doses that we’re proud to share with you. We don’t hide anything in a “proprietary blend”, so you always know exactly what you’re putting into your body.


An effective dose is the amount of an ingredient that has been shown to deliver results. Some supplement brands add a sprinkle of an ingredient just so they can say it’s in the product. Signature supplements always include enough to get the job done.


Trendy, flash-in-the-pan ingredients come and go. But time-tested, gym-proven ingredients are what you need to help you achieve your fitness goals. That’s what you’ll find in Signature products because that’s what works.

Nice flavour, really effective and more of a clean energy feel

  • 9 Fruit Punch

This is a very effective pre-workout with good flavors. I just wish it had less caffeine (or even caffeine free) and contained creatine. Otherwise, this is an awesome product.

Tastes great, but left my heart racing long after my workout.

  • 10 Fruit Punch

This preworkout gets you super wired for your workout and it tastes amazing too! Awesome price for the quality.

  • 1 Fruit Punch
  • 1 Blue Raspberry
  • 1 Cherry Limeade

Horrible flavors. Tried them all and very bitter. Could have put more effort. Me 2 prewo that is pretty basic. Would have expected more from them. Spend your money on something better.

30 minutes after taking this I would know it was working and i would get fired up, literally. My face would get very warm and I knew it was time to workout. Great boost in energy and the taste was above average. Will order again.

Bodybuilding's Fruit Punch preworkout was a great, moderately dosed caffeine stimulant that gives me the energy to get through a early AM workout before a long day at work. With great taste, easy digestion and a moderate pump that wasn't too overbearing I'd recommend this preworkout for moderate-caffeine users looking for a decent pump without the crazy stimulating components of most other preworkouts on the market.

  • 8 Fruit Punch

I’m not a huge pre-workout person, and after being off of entirely it for a while I wanted to ease back in. With only having 200mg caffeine its definitely on the lower end compared to other pres on the market, but it gets the job done if you’re not used to taking caffeine/stimulants regularly.

  • 9 Fruit Punch

Pretty great preworkout. I'd say it's more on the beginner side of preworkouts (great for those just starting to take pre!). Flavor is great, mixes nicely. Wears off a bit faster than I would like (probably because I'm used to stronger pre's). Overall great!

Product gives me energy for my 5am workouts, but the taste is nothing to write about. Taste like a mouthful of powdered sugar. I wish the taste was better.


Being off Pre for a while, I started our with half a serving, and it was perfect. Good energy throughout my entire workout, and focus too. Would definitely recommend.

  • 9 Fruit Punch

It gave a great pump and good energy! I don't like taking too much caffeine so this amount was perfect for me. It did not make me feel jittery like some preworkouts do.


Decent energy, focus, endurance and pump. I do feel like 200mg of caffeine is on the lower end for what I’m used to from preworkouts

The best way I can describe this pre-workout is that it doesn't hit too hard, but at the same time it hits hard enough to get the job done (with one serving). If one serving isn't doing much for you, then you can do two servings, but I would not recommend doing so on a day-to-day basis. Taste: The fruit punch flavor isn't bad at all, however, I can see myself getting tired of the taste in a few months with repetitive use; it reminds me of a candied version of Hawaiian Punch if that helps you think of the flavor. Mixability: While you can certainly throw a scoop in a cup full of water, it might take some time to fully mix it, so I usually just throw it in a water bottle or shaker cup. After you shake it up there isn't anything floating around or sinking to the bottom like some other pre-workouts. Ingredients/Performace: The inclusion of L-Citrulline is a nice, especially at a 5-gram dosage, but the beta-alanine is a bit low for me with one scoop; 1.5-grams. The caffeine is in a nice sweet spot at 200-milligrams which is capable of providing me with a decent amount of energy to wake me up and get me through a workout. If the 200-milligrams is a bit low for you, then you can certainly take two servings, however, I would suggest not having caffeine from any other source throughout the day. The L-Leucine is a great addition as well. Miscellaneous: I found that one level scoop of the powder is not accurate with the serving size of 13-grams listed on the label, instead, it reads 17-grams on my kitchen scale. The difference is relatively minor considering you won't be approaching a dangerous level of caffeine, but some consistency and accuracy would be nice. As for the packaging, I find that the tub is way too big for the amount of powder you get, for reference, I can probably put two tubs worth of powder in one tub and still have a decent amount of room left. Also, I am not sure how it might impact the pricing of the product, but I feel like replacing the sweeteners with something more natural would be a great plus. If you get the fruit punch flavor, prepare to see some bright red fluid as the FD&C red no. 40 really does its job coloring the product. All in all, this pre-workout is not bad at all, especially considering the price per serving, I will definitely consider keeping this in my supplement library for those days where I don't need as much caffeine, but still want a great pump.

When it comes to flavor this is definitely the best Fruit Punch I have had. I am not usually a Fruit Punch person because it is too sweet and lingers around, but this preworkout impressed me. When it comes to a kick, it gets the job done for the price! Decent amount of Beta Alanine and caffeine. It is not overwhelming but it gets me in the lifting mindset!
