Stim-Free Works. Here's Why.

Stim-Free Works. Here's Why.

I get it. Stammpede isn’t for everyone. Not everyone needs a full boar, you-know-what’s to the wall workout every time. Some people (like me) are sensitive to stimulants. No matter your reason, sometimes you just need a little boost to get through your workout. That’s where our brand-new Stim-Free Stammpede comes in. All of the session-destroying focus of Stammpede with none of the Beta-itch we all know (and love). To help you get more familiar with our Stim-Free formula, we decided to put together a little survey of the key ingredients.

L-Carnitine is a compound that is naturally produced in your body, but can also be useful when supplemented. L-carnitine helps the body turn fat into energy in a process known as lipolysis. It does this by aiding transportation of fatty acids into mitochondria within cells. Mitochondria can then use the carbon and hydrogen atoms in the fatty acids to create energy in the form of ATP. Most of your body’s carnitine is stored in cardiac and skeletal muscle, which makes sense, since these tissues are particularly energy-intensive and require a lot of replenishment. 

Lipolysis isn’t the body’s preferred method of energy production, which is why you’re always told to get your pre-workout carbs, and not your pre-workout fats. However, efficiently turning fat into energy can be really helpful during a long workout, or if you’re trying to manage your body composition. 


Much like L-carnitine, taurine is also mostly found in your heart and skeletal muscles, with some reserves in your eyes. Taurine helps your body maintain proper hydration/electrolyte balance, which we all know is critical for training. It also supports CNS function by protecting cells and cell membranes, as well as modulating the function of mitochondria. Taurine is also believed to have a number of exercise-specific benefits, including improving oxygen uptake, increasing time to fatigue and decreasing recovery times. It’s pretty hard to beat those benefits when you need to grind out a lift. 


Works as a precursor to many neurotransmitters, but, importantly, dopamine and norepinephrine. Dopamine is known for its role in our mood and enjoyment, but it is also important for movement. For example, the death of dopamine-producing cells is a major part of the progression of Parkinson’s disease. Norepinephrine, on the other hand, is important for arousal and attention. If you need to get hyped up and focus, you want to make sure you’re producing enough norepinephrine! These benefits have been shown to be helpful for improving cognition under stressful conditions. You’ve gotta be able to think on your feet! 

PEAK 02 

Now this ingredient is probably one you haven’t heard of before. Peak 02 is a proprietary blend of several powerful mushrooms that help your body adapt to stress and work longer. The combination of mushrooms has been shown to increase O2 uptake while decreasing lactate production, which leads to decreased fatigue overall during training. Some of the stars of the show are Cordyceps (no zombies here), Lion’s Mane (which you might recognize) and Shiitake (Morning Ritual, anyone?).  

Cordyceps, long used in Traditional Chinese Medicine, is thought to have numerous benefits. For our purposes, Cordyceps’ ability to aid your body in the production of ATP is critical. This increased energy efficiency may lead to better performance and oxygen usage in exercise settings. 

Lion’s Mane, our brain-boosting super mushroom, is renowned for its ability to protect your neurons. Known as neuroprotection, this effect can combine with the positive effects of exercise to help make your brain an iron fortress of health. Lion’s Mane also has powerful antioxidant abilities, which is ideal for recovery from metabolically stressful exercise. 

Last but not least, Shiitake mushrooms are one we’re all probably a bit more familiar with. These mushrooms are popular food items, but they also have a number of health benefits. On top of having a number of healthful micronutrients like copper and selenium, the polysaccharides in Shiitake are the stars of the show. Poly-(meaning many)-saccharides (meaning sugars) are complex sugar molecules that can often be beneficial to our health. The letinan and beta-glucan polysaccharides in Shiitake can help protect your cells from damage, and boost white blood cell production. 


Neurofactor is a whole coffee fruit extract. Don’t worry, there’s no caffeine here! Just a bunch of great plant molecules called polyphenols. Polyphenols can have a lot of different activities in the body, but the specific ones in Neurofactor seem to increase production of a molecule called brain derived neurotrophic factor, or BDNF. BDNF plays a number of important roles in neurological health, like maintaining neurons and improving plasticity in the brain - which is your brain’s ability to change itself. Exercise is another great trigger for BDNF production, so you can’t go wrong combining your training with Neurofactor. 


Huperzine A is a compound that is commonly found in two mosses: Chinese club moss and fir club moss. Huperzine A works to increase levels of acetylcholine, a neurotransmitter that is responsible for muscular contractions as well as learning and memory. The compound can increase acetylcholine levels by inhibiting the activity of the enzyme that breaks down acetylcholine. The presence of acetylcholine in particular brain structures is critical for learning, which sounds important if you need to learn a technical movement, or even just remember how many reps you’ve done!
