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.

Mixes well. Gave a nice flow of energy as I worked out. A slightly tangy taste however likely due to possibly the caffeine? I might try another flavor next time to test that out.

So it mixes with just a few shakes, no clumping at all and while it does not have any floaters…. dat foam. It is oddly thick, like the head on a good beer. It doesn't settle really and is thick (for lack of a better description). Blowing on it to get it to disperse was a bad idea as it just blew out of the cup and stuck to my beard; other than that issue I had no problems mixing it up. I mixed it again and let it sit overnight in the fridge, and this gave the foam time to go down. When I shook it up again before having it, the foam was a non-issue; it got a bit when I shook it but it quickly went down on its own instead of staying like it had before. It is sweet, and has no acidic ‘bite’ that pineapple normally has; kind of like a candy-like pineapple flavor. The actual pineapple aspect is pretty weak though, if you did not tell me upfront it was just pineapple I would have said a tropical punch style flavor with a stronger pineapple presence. When I see pineapple as the sole flavor I expect much more intensity from it, and while I liked the taste, it just was not what I’d say is a strong pineapple flavor. At 200mg of caffeine per serving, it is a mild amount, and enough to get you up and going; the 1.5g of Beta Alanine wasn’t enough to get me the tingles, but I am a bit used to it. At one scoop it woke me up, gave me the energy to hit the weights and finish through my routine with no problem, and throughout I had some pump but nothing too extreme. Again, with the more laid back ingredients I did not expect to feel anything skin bursting (5g of L-Citrulline) or ravenous energy. This was a decent pick me up though and I feel most people who do not want to feel cracked out would enjoy it. The focus I felt was nothing more than what I would normally feel, though this really does not have anything in there to aid this, so I had not expected much in this area. At 2 scoops, because that’s how I roll, it was a lot more energy, much more to my liking, still no BA tingles but I need more like 5+ grams for that; pumps much improved from 1 scoop. Not bad at all since the citrulline is pretty much the only contributor here, but at 10g in 2 scoops it’s kicking in good. I enjoyed it a lot more with the extra caffeine from 2 scoops though, as one would expect 400mg of caffeine is a great way to get ready to smash it. Still no focus boost, but again I did not expect one. This would be a good pre-workout for cardio if I were to use it consistently, energy to get me moving, but minimal pumps to interfere with running or other movements. For lifting I enjoy a bit more from a pre-workout, more pump ingredients, more focus ingredients, and definitely more caffeine unless I consistently 2 scoop it. For someone looking to get a boost but not wanting the more exotic profile that some pre-workouts have, this is a great option though. It keeps it basic, and that can be a good thing.

I have tried several other popular pre workout brands (GNC's Beyond Raw, C4, Evlution + Pump Mode), but this is the best I've used. It tastes great, gives you the right amount of energy for pushing through a heavy workout, and is priced right. The only downside I have found is the mixability could be a little better. Otherwise, a solid product and something I'll be stocking up on.

had the chance to try some samples. Pretty decent preWO but definitely not the best i have had. Decent pumps and got me through the workout but the flavoring was definitely not the best, pretty much have to shot gun it to get it down. I will stick with my go to thats has some better dosages and flavor a bit more on point.

I have bought three different flavors of this product. Blue Raspberry and Fruit Punch have strong flavors which I enjoy. The Watermelon Lime was awful. I had to drink it with out stopping as the after taste was bad. Outside the flavor this product gives good energy and very good price. Just beware of some flavors.

Took too much of this my first few times because I thought I knew my tolerances, what a wild ride. Stick with their serving suggestion and it gave me decent energy to power through a full workout. Taste was different with the pineapple, but pretty good to me

  • 8 Watermelon Lime

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.
