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.

Great Product. Gives me a good pump and focus without going overboard with the jitters. Granted, I consume caffeine and pre-workout sparingly, so take it with a grain of salt. Could have low impact for those that consume often. For the taste, DILUTE IT. Recommended 8 oz was not nearly enough. It tastes extremely sweet/concentrated. I found when I used 20 oz, the flavour tasted great and I could sip it before my workout. Rather than slam it back because my taste buds couldn't handle it.

As a product, I thoroughly enjoy it. Very rarely do I take a full scoop as I workout in the evenings. I have a small scoop that came from a tub of Signature BCAAs which I have thrown into the tub and use that as one serving so it lasts me a long time. On the weekends (or during my Friday night workout extravaganzas) I take two scoops, which I probably shouldn't because it's just too much of a boost for me and I end up getting distracted from my workout by about 500 other things. Go figure. Definitely need to give it a thorough shake as it can be quite foamy if you don't. I also make sure to rinse my shaker right away just to avoid any odd smells (not saying it does, but I use the shaker for three or four different flavored things and previous things have definitely put a smell on the plastic). Flavor wise, the blueberry lemonade is great and the watermelon is just sickly sweet, but still doable. That's the one I usually double scoop (aka one serving) and slam on the weekends or Fridays.

This is my go-to pre-workout. It tastes great, dissolves well and gives me the pump and focus I need to fuel my workout.

Good product, took about a week of using it for the tingling went away. I lift heavy for about 45 min each day and the extra energy from this last about another 20 minutes after I am done. Well worth it.

Solid product. Does what it’s supposed to. Taste is fine. I know a lot of reviews focus on taste but I honestly don’t pay much attention. Just slam it anyway.

The Tropical Pineapple probably tastes closer to pineapple juice than any other drink mix product I have ever had, to include water flavor enhancers. Taking it 30 minutes prior to workout, I found it provided just the right amount of pick up to keep me locked in and push through my workout after a 12 hour workday while not hindering my ability to get a good night's rest.

I really like this preworkout, with Pineapple being my favorite. However, I had some difficulty mixing it in anything but a blender bottle. It doesn't give me that tingly feeling that some other preworkouts do, but I also don't feel crazy jittery or like my heart is going to explode. It has a subtle enough kick that I don't worry about using it for my cardio workouts, whereas some other brands I would only use for lifting. Will get this again.

I’m okay with the product and it does work as a pre workout, there is just better out there. I did experience increased focus and was able to tell I was getting a boost, I have just had better. I tried this product because the Signature brand creatine and protein have worked so well for me that I switched to them. I probably won’t switch to this brand of pre though.

This preworkout works as it should but man the taste is terrible in my opinion. The is such an odd taste and a weird after taste. If you can get past the toxic taste then this product is great...

Didnt give me crazy energy, no tingles or anything. I was able to get a great workout with one of the best pumps I have had and had plenty left in the tank. 9/10 only because I would have liked a bit more initial kick, I will revisit if anything changed. Taste is amazing the best tasting preworkout I have ever tasted. If it wouldn't kill me I would drink it all day.

I don't know why this product has such a high flavor rating. I have tried many different pre workouts, so I know that they all have a pre workout taste but this one is absolutely unbearable. When it mixes with water, a gritty foam solid layer forms on the top that won't go into solution. The taste is like acidic rotten pineapple with a lingering aftertaste. I cannot even speak to the efficacy of the product because I haven't been able to choke down enough to see any effects. Maybe I got a weird batch, I don't know.
