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.

Seems to give good amount of energy and makes workouts easier, but do yourself a favor and do not get the tropical pineapple. Horrible flavor to take down

The overall taste is good but the low amount of caffeine is kind of a bummer. The dosage of Beta-Alanine is also kind of low compared to the clinical dosage of 3.2g Overall it's a good product if you're just getting into using a preworkout supplement, but there are much better options out there for the price.

By far one of the worst pre-works Ive ever used! The taste is like Splenda at first then after 2 mins of drinking it. It leaves a very strong chemical taste. Will not be ordering this again! Also it came clumbed in the container.

The taste was great. Mixed pretty good. Had a weird foam on top. Crashed so hard after. I could feel the drain. Do not recommend.

This is really a good product. Every ingredient is listed on label and nothing is hidden. I take this product at around 6PM and doesn't cause me sleepless nights. On the top of it, the flavor is really tasty. I am planning to stick to this product.

Good effects within a few minutes of drinking the product. This product has given me the best focus of any pre-workout I have taken. Pump/energy levels are well above average. I like the fact that this supplement does not have creatine; no bloat. This is definitely my favorite pre-workout to date.

HOLY CRAP, WHERE HAS THIS BEEN ALL MY FITNESS JOURNEY?! Not only was I able to complete my original resistance/cardio workout much easier, I had so much energy afterwards, I went on a 30 minute run. It's so rare for me ever to get to near-failure in a workout because of energy issues. I am so stoked to have this in my life now! It tastes like a sno-cone, which gives me a few moments of joy each time I drink it. I am not high-key obsessed with this product.

Admittedly Im not a big fan of prework outs, but I tried this one and there were noticable benefits. There were also some draw backs. heres my summary in bullet points: Pros: energy is good pump is good feel like a supplement has been taken i.e. feel it 'kick in' flavor is tolerable mixes well, even in a water bottle or cup only one or two wierd ingredients cons: makes me itchy, especially on my face doesnt last a real long time, i need to take it within about 30-45 mins of going to the gym or it will wear off. flavor could be better (still just tolerable) serving size is kind of large Overall i think if i was in the market for a preworkout, this would get the job done for me

This pre is pretty good. The taste is not the best I’ve had... but, it works pretty good. I like the tingle it gives me, and i don’t crash afterwards.

Perfect amount of Energy without a massive crash or that "Cracked out" feeling... I only used about 4oz of water and it mixed perfectly. Flavor was great and didn't over power you... Will be using every time I need that little boost

Good preworkout, got the tingles without any sort of crash or feeling too wired/jittery. Fruit Punch flavor was a bit too artificial and sweet, kinda tasted like bubble tape but it got the job done.

I have tried almost every preworkout on the market. I can honestly say this is one of the best I’ve ever tried. No crash, sustained energy, and mixes and tastes great. I’ll definitely get this again!

Mixability is some of the worst I've ever seen, mixing my shaker hard enough to get the preworkout blended into the water is almost a workout in it of itself. It works well enough to give me a boost in teh gym but wouldn't be effective enough for those with a higher tolerance or looking for more stim. As for flavors, if you enjoy eating pineapple you will probably love the pineapple flavor. it's like someone managed to take the fruit and turn it into a powder. Unfortunately I don't like pineapple that much it turns out. Fruit punch tastes exactly like a glass of fruit punch, so if you like fruit punch juice you'll like this flavor.

I can't say it better. It's weak. You will be sweaty but nothing that strong as Reign or Mesomorph.
