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.

Amazing blend of ingredients such as Citrulline that have science behind their efficacy instead of an overpriced mix of pseudoscience BS. Perfect amount of caffiene. People over-dose with 400mg caffiene preworkout and induce a parasympathetic attempt at homeostasis. It tastes good too by the way, so any poor ratings most likely come from morons who regularly abuse caffiene and think tingling skin from excess niacin actually increases workout capacity.

The Fruit Punch flavor is definitely strong. Directions call for it to be mixed with 8oz of water, but I dilute it even more using 12oz to keep the flavor manageable. Tingles for me start about 15 minutes after taking it, so I know it's working. I'm not a big fan of raspberry, but I'll try the Blue Raspberry flavor next to see if I like it better than the Fruit Punch.

Fast acting and long lasting. Great product for those working out at lunch and not needing an intense charge.

I pair this with a Teacrine pill about a half hour before a workout. I feel great throughout the entire session whether I'm lifting or doing cardio. There is very little fatigue and I'm able to lift harder for longer so I couldn't ask for more. NOTE: This isn't going to make you feel jacked up or electrified but unlike those preworkouts that give you a ton of fake energy from caffeine, this stuff acts as a lasting fuel

Whenever I first switch pre-workouts, there is always a bit of initial shock in getting used to a new flavor. This tasted a bit more chemically than my last pre-workout. But after taking it a few times, its not as noticeable. I didn't really get that tingly feeling, or feel as "amped" as I would like to feel. But no side effects either. Probably will not become one of my regular pre-workouts, but could be a cheap option if I am trying to work with a tighter budget at times.

Not a bad product and it works but one scoop isn't enough! I usually take one & half scoop and it gives a good kick! not bad! Fruit Punch tastes like a cough syrup! It isn't horrible but reminds me when I was little and being forced to take the cough syrup, not a pleasant thing to remember :/

You can feel the tingle starting about 15 -20 minutes after taking it and provides good energy throughout the workout.

Got a really good kick out of it, and an awesome pump. It definitely works. Beta-Alanine tingle started about 20 minutes after drinking it, that may just be because I haven't used pre-workout in a while, but I don't mind the tingle. It lets me know it's kicking in lol. Only negative is that the fruit punch flavor is pretty gross. I'll be trying the other flavors and hopefully they're better because it took some effort to get it all down. Still I would definitely recommend this to anyone looking for a cheap and effective kick in the ***

Took this for the first time yesterday. I'm not new to pre but have stuck to brands I like...Kaizen and Nitraflex. I was feeling especially tired and unmotivated for my workout. I took a scoop and within 30 minutes, I had so much energy and killed my workout. I had a tingling sensation in my fingers...I don't ever mind that though and I hear it's from the beta alanine. The flavor could be better...a slight bitter taste, but I didn't mind it. For the price, it's a good product and I will repurchase as I want to support the brand.

Give this product a try just out of loyalty to the company name. Never would have imagined Bodybuilding.com would have put their name on such a horrible product. Taste is so horrible i could hardly stomach it and I've drank some BAD supplements from back in the day!!!

This is a very effective pre-workout with good flavors. I just wish it had less caffeine (or even caffeine free) and contained creatine. Otherwise, this is an awesome product.
