Gym Rats does a lot of things differently with its pre-workout Rat Fever

If you’re a fan of unique supplements and are looking for a different kind of pre-workout to try, you’ll want to check out the brand we have for you today. The name of the company is Gym Rats, which is very new with just the one product available at the moment called Rat Fever.

While the name of the brand and its only supplement are kind of interesting as they are, that’s not the most unique thing about Gym Rats. All you need to do is take one look at the brand’s product Rat Fever, and you’ll see what we mean, as the pre-workout is produced and packaged unlike any other supplement on the market.

The first thing you’ll notice about Gym Rats’ Rat Fever is that it doesn’t come in your typical powder tub. Instead, the product is packaged in a clear plastic box filled with a total of 30 test tubes, with each one of those having exactly one serving of the pre-workout.

As mentioned Rat Fever is produced and packaged unlike any other supplement we’ve ever seen, so you may be wondering what’s so different about how its production side? If you take a closer look at the powder inside the tubes, you’ll notice that it appears to be color separated or at least stacked in some way.

What Gym Rats does with its pre-workout is pour each of its ingredients into the tubes, one by one, which is why you can see different stacks of color. For example, the brand fills the tubes with creatine, then beta-alanine, and so on until everything is in there. It is because of this technique that Gym Rats says Rat Fever is far more accurate with its ingredients than its competition.

The formula behind the first Gym Rats product is of course in tune with its transparent packaging and is 100% transparently dosed, listing all of its ingredients with doses. The combination making up the pre-workout Rat Fever is fairly simple with 4g of beta-alanine, 3g each of citrulline malate (2:1) and creatine monohydrate, half a gram of agmatine, 450mg of dicaffeine malate, and 50mg of theacrine.

The entire Rat Fever combination promises to deliver the usual mix of effects, with Gym Rats aiming for a complete pre-workout experience. According to the brand, the supplement will give you precision focus, sustained energy, and wicked pumps.

Being a very new brand, Gym Rats isn’t available in too many places just yet. Currently, the brand’s website truegymrats.com is where you need to go to get Rat Fever, priced at $39.99 for 30 servings, with three flavors to choose from in Tequilla Lime, Blueberry Mojito, and Strawberry Margarita.
