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.

Great flavor, but you’ll need two scoops of this to get any kind of decent pump.

This is an amazing product, especially for the price. Clinically dosed ingredients shown on the label. Flavor was good not great, but that is not especially important to me. Energy came on strong and felt clean. Also gave a decent pump. This is definitely my new "go to" pre workout. Pick up a tub and enjoy!

It seems as I am not the only one to suffer the side effects of this pre workout. First of all, the tropical Pineapple flavor is atrocious, I could not drink it with water and had to resort to dry scooping, even then, it was bad. I have seen other reviews of people suffering from nausea. I had the same side effects. Don't get me wrong, this pre workout WORKS. But after my workout I struggle to eat due to the bad nausea. I do not believe it to be the caffeine as I've taken much stronger and have been perfectly fine.

Honestly because of the overall review, I was a little hesitant to purchase this but I’m glad I gave it a chance. Really good preworkout it gives a good lasting pump. Take your chances on it, you’ll be glad you did.

Terrible aftertaste, has the consistency of a really thick bloody mary no matter the amount of water used and even though i've taken higher dosed preworkouts before, this it has given me really bad nausea each and every time within 40 minutes. Leaves clumps of what looks like Styrofoam on top too.

This has to be the best pre-workout I’ve ever had. Fruit punch tastes delicious! It tastes like Cherry Kool-Aid, I’m not kidding! Definitly not sour/bitter tasting like Pre-Jym. Sticking to this as my main pre-workout from now on.

If I didn't drink this after 9 hours of work before heading to the gym, my workouts would suffer. This definitely helps and tastes good too.

I don't understand all the negative reviews. A real preworkout is supposed to provide quality key ingredients, not of bunch of fillers and additives. Anyways, preworkout was solid, if you want more boost, take 2 scoops. Used a bunch of preworkouts, this one is one of my top favorites. Gets to the point and allows my workouts to be solid. I wish the dosage for L-Citrulline and Beta Alanine was a bit higher, otherwise, for the price the preworkout is solid.

What's this? A Pre-workout that's not full of BS garbage, just the stuff that's known to work? Who does that? Very few supps companies, and they're about 2-5 times the price. Nice work BB.com. Some folks seem to have issues with the taste. I have no idea about that. I dump the scoop in my mouth and wash it down with water. Lifting within 30 minutes. Nice pumps, and vascularity. Note: I'm a caffeine junkie, so I get no real energy boost from it. If you don't ingest caffeine like an idiot like me, it'll probably put some pep in your step. Also like the additional electrolytes. Walking about 20 miles a day, this helps to keep cramping from screwing up leg day.

I have tried 3 other pre-workouts and sadly, this is the worse amongst the 4. I feel no increase in strength or any stimulation to power my workout. Instead, it gave me sleepless nights, resulting to difficulty in working out the next day. Hopefully BB will improve their formula.

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.
