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.

I've tried em all. Original c4 new c4 vaporx... I purchased a BUNCH of BB products before the end of the year we had to force ourselves to down the body building brand preworkout. It was rough.

overall a pretty good pre workout. The blueberry lemonade flavor isn’t the best but I’m not super interested in taste. The ingredients in this ore workout are exactly what I’m looking for, and honestly I’ve had some pretty stellar workouts since buying this. Will definitely buy more.

These are good pre workouts. Enough caffeine without being over powering. They do help with the gas tank to push out an extra rep or two. The flavors are ok, Fruit Punch is the best in my opinion. However, it's only 8oz of water. Just drink it, and go work out!

Didn't seem to give me the boost I wanted compared to other products I have used in the past.

I've never had pineapple as a pre-workout flavor, so I was a little skeptical to try it, but it's pretty good. This is a decent pre-workout, it's not over the top, jittery energy, but a mild boost which is what I was looking for. I'd recommend it. I just wish they'd remove the food dye and it'd be a banger.

I wish they skipped the food coloring--makes your stool blue! Otherwise, works okay.

I rarely write reviews, but I had to for this one. Bought this on sale & so glad I did. It’s a large scoop (14g), but a very fine powder & mixes smoothly. Great consistency and the pineapple flavor has a great taste. Not bitter and the perfect amount of sweet. Also, a great mix of ingredients and nothing you don’t need. My new favorite pre, for sure.

I’ve been very happy with all of the supplements I’ve used in the past. This one, unfortunately, is the worst tasting I’ve ever had. Does get the job done though. I will not buy this flavor again.

Cherry Limeade is easily a 1/10 for flavor, but if you can stomach it, it's a decent pre workout. That being said, Blue Raspberry tastes the best and helps boost you through those heavy lifts.

If you have ever tried a bad knock off of NyQuil you will have somewhat of an idea how bad this flavor tastes. Tried it twice and could not get it all down either time. No idea if the product works at intended as I could not get that far with it.

First let’s talks about the flavor. My goodness this is the worst flavor out of any supplement I’ve ever used. I’ve used supplements for over 10 years now so that just explains how bad this cherry limeade tastes. I’ve had a different brand of cherry limeade and I can drink it all day long but definitely almost threw this one up. Very hard to chug it. The product itself worked as it should however. I felt energized and not very fatigued. For the price it seemed like a good buy but I’m not sure I can even drink it a second time... yikes.

It’s a preworkout that gets the job done. Nothing special. Not sure about the other flavors, but the cherry limeade flavor tastes like spicy garbage.
