Product Overview

Bodybuilding.com 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.*

Bodybuilding.com Signature Pre-Workout tub

L-Citrulline

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.*

L-Leucine

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

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, Bodybuilding.com 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.

TOTAL TRANSPARENCY

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.

EFFECTIVE DOSES

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.

RESEARCH-BACKED INGREDIENTS

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.

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.

  • 7 Watermelon Lime

Again a very typical watermelon flavor. I can say, that signature line flavors are very accurate. You get exactly what you expect. It's a sort of "old school" artificial watermelon flavors, but definitely drinkable, no complains. Mixed better, then I expected. I've seen some very foamy images of this pre, but it mixed pretty okay. Energy & focus - 2.5/5 Exactly what I expected. I'm a stim junkie so energy improvements were moderate. Mostly used this pre, when I didn't want to overstim myself (in the evening or before my job) Pumps - 3.5/5 L-citrulline is my favorite pump ingredient and pumps were solid.

Both flavors I have on hand are astounding. Often, workout supplements have a strong chemical taste/aftertaste and/or just an awful flavoring system in general not masking the ingredients. Both the Watermelon Lime and Blue Raz are phenomenal in this regard. The profile is simple and to the point. A bit of caffeine to push the mental aspect, a little bit of Taurine to aid with fluid shifts and decreased cramping, and some Leucine and Citrulline to help push the physical bounds. At this point, I prefer profiles like this, and the added mineral complex is great. Too many products try to attack a preworkout with too many avenues. Some staples, even some Beta Alanine to keep from having to dose that separately, with a good flavoring system and we're good to go. Good job with this product, BBcom! I'm using a separate tub of whey and creatine mono to round everything out on my end - conveniently also BBcom thanks to some good deals in the past!

  • 9 Blue Raspberry

Normally I am not a fan of blue raspberry, but I do have to say that I was overall pretty pleased with the way this tasted. I usually workout around 3PM, and I need something that will give me a pump, but NOT put me over the edge so that when I get back to my desk I'm not unfocused. I'm running through a DEEP PSMF defecit and this STILL gave me pumps. Happy with the profile as well, all around solid.

Solid pre workout. I'm a Dawn Patrol lifter and this got my eyes open and gave me enough go to power through my 45-60 minute sessions with a nice pump. Watermelon Lime has that artificial Jolly Rancher watermelon flavor to it. Not the best tasting supp of all time but plenty good enough to go do easy. And come on, it's pre- : you slam it down quick and get to work. This mixed up easily in both a shaker bottle and with a spoon. A few small clumps with the spoon, but still easy to work with.

Kicks in fast (for me usually 10-15 minutes) and keeps me going for quite a while. Also makes my pump feel amazing, and the increased blood flow gives me an extra half inch or more in size compared to a natural pump. Highly recommend.

Works very well. Too much caffeine for me. Had to cut the dose in half, but that just means more servings!

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.
