Review: Been using this product since June of 2021. My typical activities are Olympic weightlifting and accessories to accommodate for the two main lifts. Judging by the ingredients alone, this is quite literally the best stim-Free pre workout on desertcart. Take a look and compare the ingredients list to any other supplement and you'll see that this is true. However, that brings me to the biggest con of this supplement. Personally, I hate the taste of this stuff. Either flavor is hard to drink, as it tastes like cheap candy that is way too sweet. I searched in vain to find some other preworkout, but they all were underdosed or missed key ingredients. So, if you're like me and would rather have the best ingredients at the cost of the taste, then this one is for you.
Review: Taste is alright, I add it to a Gatorade so hard to say. No jitters which is the ultimate plus side. I've seen results. Just wish they had a subscribe and save, their website doesn't even seem to give discounts.

### ⭐⭐⭐⭐⭐ Review
*by C***S on 24 March 2021*

One of the best pre-workouts I’ve ever used. I’ve been a stim junkie for years but was building too much of a tolerance to caffeine to the point where it no longer affected me. I decided to take a couple weeks off of caffeine and bought this particular pre workout to use instead. The focus I get while on this product is ridiculous! I’m zoned into what I’m doing at the gym with such intensity as I haven’t had in a long time. The pumps I get from this are decent, but not as crazy as I was hoping for. HOWEVER, my strength has gone through the roof somehow, and I’ve hit several new PRs while using this. I originally wanted to take a couple weeks off from caffeine but now it has been nearly a month and I’m seriously considering buying more of this product to use as my go-to pre-workout. Oh, and as for flavor it tasted fine. I got watermelon and it isn’t bad at all. Nutrabio makes some very high-quality products. They’re expensive, but you get what you pay for. I highly recommend this pre-workout.
