Best Flavor & Energy Boost

I've tried a few different pre-workouts and this one is not only effective without the crash, but also by far has the best flavor. It's not overpowering, is easy to drink, and tastes more like a sports drink than a pre-workout. Definitely worth a try if you're new to drinking pre-workout! Can't wait to see what MCS comes up with next!

Best preworkout I’ve found!

Love the energy, focus and intention that my workouts get from Pre-S! When using Pre-S I find it easier to get into a “flow state” and get direct translation to my workout intensity. 10/10 recommend for any athletes looking to level up their workouts!

Love it!

It’s been a while since I’ve used preworkout, but I decided to try Motor City Supplements, and I’m really glad I did. I started with just half a scoop as recommended, and it turned out to be the perfect amount for me.

Normally, preworkouts leave me feeling overstimulated and jittery, but not this one. It gives me the energy boost I need without feeling like I’m jumping out of my skin. Plus, the blue razz flavor is amazing— not overly sweet which is awesome.

I’m excited to check out more products from MCS!

Best Pre-workout if You're New to Pre-Workouts

Coming from the perspective of an athlete who shies away from supplements and pre-workouts, I'm shocked at how much I love this product. I've been using it regularly for a few months. It really does kick in within 30 min after drinking it, leaving me ready to crush my workout. The energy boost is timed perfectly without making my heart rate shoot through the roof, which is why I shy away from pre-workouts to begin with. The flavor is also great and subtle. I highly recommend the product.

PRE-S Review

I'm new to pre-workouts, but this was recommended to me by a friend. Since taking PRE-S, my lifts have gone up, I stay focused during lifting, and the flavoring is amazing. Can't wait to see new products from MCS.
