STIM Pre-Workout is a powerful preworkout supplement that contains 450mg of caffeine in each serving. Learn if it’s the right choice for you today in our STIM Pre-Workout review.
What is STIM Pre-Workout?
STIM Pre-Workout is a preworkout supplement made by the team at Blackmarket Labs. The first and most noticeable thing about STIM Pre-Workout is its dosing: each full dose (1 scoop) of STIM contains a whopping 450mg of caffeine anhydrous – which is approximately the same amount of caffeine in 5 ½ cans of Red Bull.
There’s also 6mg of Huperzine A and 5mg of yohimbine – you know, just in case the caffeine didn’t give you enough energy. There’s also 3.2g of beta-alanine to soften the harsh edges of caffeine.
Obviously, STIM Pre-Workout is designed for those who are serious about boosting their energy before a workout. This isn’t for people who are sensitive to caffeine, and you probably shouldn’t take it in the evening (at least, not if you want to sleep that night).
Blackmarket Labs is a Utah-based supplement manufacturer launched in 2009. The company makes all of its supplements in-house.
How Does STIM Pre-Workout Work?
Some preworkouts enhance your mental focus. Others load you up with caffeine and other stimulants to boost your physical energy. Some do a mix of both. STIM is one pre-workout that does a lot of both.
The formula contains ingredients like Huperzine A that have been proven to improve your cognition and stimulate your mental ability. Meanwhile, caffeine amps up your physical energy. You get a full-body jolt of energy while letting your mind stay focused.
Taking 450mg of caffeine in a single dose can lead to jitters, heart palpitations, and other unwanted effects. That’s why Blackmarket has softened the edge of caffeine using yohimbine, described as “a heavy stimulant that also works as a fat burning compound.
Blackmarket doesn’t list any studies or research that has been performed on the supplement thus far. However, the individual ingredients within the formula are backed by a significant amount of science. It’s no secret that caffeine, vitamin B12, and beta-alanine all boost your energy for example (after all, these are the same ingredients found in energy drinks).
STIM Pre-Workout Ingredients
There are three different flavors of STIM Pre-Workout, including Tropical Punch, Tiger’s Blood, and White Noise. Each one has a slightly different ingredient’s list. The Tropical Punch formula, for example, contains no vitamin C, while the other two flavors do. All three also contain different flavoring compounds. The core energy-boosting preworkout formula, however, is the same across all three.
Here’s what the original Tropical Punch formula looks like (1 scoop / 7.3g dose):
-20 Calories
-1g Carbs
-1g Dietary Fiber
-60mcg Vitamin B12 (1000% Daily Value)
-15mg Sodium
-3.2g Beta-alanine (CarnoSyn)
-5mg Black Pepper Extract (Bioperine)
-721mg Energy Complex (450mg of caffeine along with theobromine, higenamine HCL, vitamin B12, and yohimbe HCL)
-381mg Focus Complex (Acetyl-L-Carnitine HCL, Mucuna L-Dopa, and Huperzia Serrata Extract 1% [Huperzine A])
-530mg Bliss Complex (Choline Bitartrate, L-Theanine, N-Acetyl-L-Tyrosine, and Hordenine HCL)
-Other Ingredients: Chicory Inulin, Malic Acid, Natural and Artificial Flavors, Silicon Dioxide, Calcium Silicate, Sucralose, Citric Acid, Acesulfame Potassium, Trisodium Citrate, and F&C Red #40
As you can see, the core of the formula comes in the form of the Energy Complex, Focus Complex, Bliss Complex, and CarnoSyn. Meanwhile, most of the flavoring and sweetening compounds are found within the “Other Ingredients” section, which varies between flavors.
What about CarnoSyn? At 3.2g, there’s more CarnoSyn than any other single ingredient. CarnoSyn is a proprietary beta-alanine formula that calls itself “the alpha of the betas”. The formula is the only beta-alanine licensed under NAI’s global patent estate for use in human dietary supplements. CarnoSyn promises to help you build healthy muscles and strength, extend endurance, and enhance peak performance capabilities. Typically, CarnoSyn is sold as part of a preworkout supplement formula.
If you’re skeptical about the benefits of CarnoSyn, then the manufacturer has posted 50+ beta-alanine studies at its official website here. The formula also holds 24 patents around the world.

About Blackmarket Labs
Blackmarket Labs was launched by Brysen Duncan in 2009. Prior to launching the company, Brysen was the owner of a struggling nutrition store in Bountiful, Utah. He was watching his business be chipped away by Bodybuilding.com, Amazon.com, and other low-cost retailers.
He came up with a plan: he would make his own branded supplements, solving problems at his own store while also helping out local nutritional supplement retailers in his area.
Blackmarket Labs is what Brysen came up with. Today, the company is unique among supplement makers because all of its operations are in-house: in one building, the company controls the production of supplements along with quality control, product development, graphic design, and more.
Other popular supplements made by the company include the Cuts Series, Bulk Series, Fierce Tone, and Raw Series. You can learn the company’s full story here.
