I have been using the preworkouts for months and love them. I know some people don't like the Cherry Limeade flavor, but I enjoy it. These preworkouts are usually on sale and are effective. I can't think of a better combo than that!

I’m not sure if it’s just me but there’s no pump with this preworkout. I don’t feel anything. I’ve tried the original jack’d 3D formula, Mesmorph, C4, and EVL and the main one I’ve been sticking to for years is EVL. Of course Mesmorph and jack’d are not regulated so they don’t count but I mentioned them just to make a point that I know the difference of preworkouts that work and preworkouts that don’t. This is not something I would buy again but I will give credit to the flavors I rated. Those two flavors are some of the best ones I’ve ever tasted thus why I gave half credit for the taste. If this product works for you, I’d recommend the pineapple and blue raspberry. They were actually pretty freakin delicious, no joke. If they redid the product and added different ingredients to give you maxed pump/amp feeling, I’d continue to buy this product but unfortunately it just didn’t work for me. Full disclaimer-I love bodybuilding signature products, I support them by wearing their t-shirts, and continue to be a long-term customer so this is not directed at, just this product.

OK the reason why I gave the flavor rating a 1 is Because the cherry limeade Is absolutely a really strong nasty flavor but over all performance wise it did give me the energy I was looking for which was really hard hitting but it was just the flavor that was bad.

Whilst the flavour wasnt really my fave, the effect was definitely one of the best. 3 tubs into this Pre now and I've been using 2 scoops since halfway through the first tub. Energy and focus are bang on, and with that much Citrulline the pump is definitely nasty (in a good way). Will be going with a different flavour next time (Tropical Pineapple was quite nice), but definitely going to use this again

ingredients are 9 out of 10, has most of the essentials. good pump and smooth consistent energy. this does make you sweat and push through workouts, you wont fatigue as quick, intra sets recovery is good. but drinking it at the beginning is like taking medicine, just isnt a good experience, might try other flavors.

First the positive, I absolutely love the boost in energy I receive from this product, it's steady and consistent, which is what one would want from a pre-workout. The cons, this is the absolute worst tasting pre-workout I have ever taken. In my lifetime I've ingested actual poison and would gladly drink it again, over the cherry limeade flavor. I'm hoping the other flavors taste even remotely better, if they do I'll gladly use this as my primary pre-workout for the foreseeable future.

I really enjoy this product! I’ve tried countless pre workouts in the past... This one is pretty mild in comparison to some, but that’s what I like about it. A little boost of energy without any jitters or crashing. And the PINEAPPLE is amazing! The flavor is so strong!! I fill an entire shaker with water and the flavor is still so intense, like straight pineapple juice. That’s what I love about it, tastes amazing. Perfect to drink on the ride to the gym. I recommend this product!

Didn't get much of a boost from the signature product. Barely any tingle at all. I've been trying different preworkouts but the one I g÷t the best results from is the pre-jym brand

Great pump, focus and energy - would be good if there was a higher caffeine version!

I have used several pre-workouts for the past 6 years and without a doubt there is not one named brand pre that compares to Bodybuilding Signature's pre-workout. This pre-workout gives me quick motivation with lasting pump for the entire workout and no crashing either. After finding this series I now stack all my supps including even my multivitamins with Bodybuilding Signature Series.

Seems to give good amount of energy and makes workouts easier, but do yourself a favor and do not get the tropical pineapple. Horrible flavor to take down

  • 9 Blue Raspberry

The overall taste is good but the low amount of caffeine is kind of a bummer. The dosage of Beta-Alanine is also kind of low compared to the clinical dosage of 3.2g Overall it's a good product if you're just getting into using a preworkout supplement, but there are much better options out there for the price.

By far one of the worst pre-works Ive ever used! The taste is like Splenda at first then after 2 mins of drinking it. It leaves a very strong chemical taste. Will not be ordering this again! Also it came clumbed in the container.
