Underground Bio Labs Panda Supps: Rampage Chaos, Extreme Pre-Workout, High Stim, Maximum Pump,
At PANDA Supplements, we strive to create something unique and different every time with our limited edition pre-workouts. This allows us to not only experiment with different formulas but also try various combinations of ingredients that we typically do not use in our Legacy Pre-Workouts. For this round, we wanted to create a new Limited Edition version of Rampage, so we knew this one had to be special, considering that Rampage is already an amazing pre-workout that hits on all levels. Our past limited edition versions of this pre-workout raised the bar, and we had to surpass and outdo them! Therefore, we made sure this version delivers an insane amount of energy, pumps, performance, and focus, taking it up ten notches from its original formula. To accommodate this incredible formula, we also opted for a bigger bottle, introducing an all-new 32 oz bottle—something we’ve never done with Rampage before. We also set out to craft an amazing flavor unlike anything we’ve done before—something refreshing and different. We combined Strawberry, Peach and our Rainbow Sherbet flavor to create Strawberry Mango Sherbet. It’s one of the best-tasting flavors we’ve ever developed, making CHAOS truly stand out from the other pre-workout flavors we have done in the past. So dive into the unknown with this limited edition Rampage Pre-Workout: CHAOS Edition. This is not just another pre-workout; this formula delivers intense focus, insane pumps, and euphoric energy. Embrace the thrill and let Rampage unleash the CHAOS within you!

Brandi… large family! –
Not worth 55 bucks get edge of insanity or something
For my honest opinion it only works on some people it worked on me I got a good pump and some energy but that’s it I did it some endurance from it but the taste is mid not worth 55 bucks

Insane pumps
Best pre workout I have experienced
Anon. –
Seems legit so far.
I have only tried one scoop at a time. But I did notice a little benefit in energy and stamina in the couple of workouts that I’ve paired with it.Obviously, you have to kind of proceed at your own risk with this sort of stuff, so I can only speak about my own experience with it. I didn’t personally notice any ill effects while using the lower amount, and I do think that it has an effect.

Good strawberry flavor , decent ingredient list
This is the second pre-workout I’ve tried from this brand. Interestingly a completely different formulation, which seems common with the brand. Lots of variation. Anyway, how does it work and what does it taste like?Effectiveness. Truthfully, it’s hard to say, but really that’s more a n issue with how much I’m taking. I only take a single scoop so as not to get too much caffeine. Ingredients list is solid and at a single scoop I feel a boost but I’m not shaking or tingling. Pump is ok but I’m also supplementing with a scoop of creatine.Taste. Strawberry with only a mild medicine aftertaste. I’ve definitely had a lot worse tasting pre-workouts but it’s also not one of those candy flavors from other brands.Comparing to something basic like OG C4, there’s a lot more going on here but it also cost a lot more. If you’re looking for a more supplement list this is worth considering but at these prices there are a lot of options. Taste is good if it has the mix of supplements you’re looking for.
