The 'Stim-Crazy' Pre-Workout

5150® High-Stim Pre-Workout is engineered for serious stimulant users and advanced athletes who demand no compromise. Powered by a "Stim-Crazy" caffeine complex (8 caffeine sources) delivering over 400 mg of caffeine per serving, this formula blends sustained energy, pump support, and cognitive edge.

Key Features & Benefits
  • Stim-Crazy Caffeine Complex (513 mg total, ~400 mg effective): Combines fast- and slow-release caffeine sources to support prolonged energy without dramatic crashes.
  • Pump & Vascular Support: L-Citrulline, Taurine, and Nitric Oxide-boosting agents help enhance muscle fullness and nutrient delivery.
  • Endurance & Fatigue Buffering: Beta-Alanine helps buffer lactic acid buildup so you can push longer.
  • Mental Drive & Focus: N-Acetyl L-Tyrosine and nootropics help sharpen mental clarity and reduce distractions during training.

Available in multiple flavors, including Tropical Rage, Pink Lemonade, Blue Ice, Green Apple, Wildberry, and Rocket Pop.

If average pre-workouts don’t push you far enough, 5150® is designed to take you into the next level of effort. Just be sure your body and mindset are ready for the intensity.

With just a single scoop of 5150® over 400mg of total caffeine will begin to take hold and course through your veins.

INGREDIENT BREAKDOWN

This well-known ingredient works indirectly to buffer acid and reduce fatigue by increasing levels of carnosine in the working muscles thereby allowing you to push your reps and sets deep into the growth zone. Carnosine consists of the amino acids beta-alanine and histidine which occur naturally in the body, and is one of the primary compounds that buffers acid in recently activated muscle tissue. An increase in intramuscular carnosine levels can increase the buffering capacity of a muscle, further delay the onset of muscle fatigue and failure, while improving muscular strength and endurance.
With just a single scoop of 5150® over 400mg of total caffeine will begin to take hold and course through your veins. Consisting of Caffeine Anhydrous, Dicaffeine Malate, Theobromine, Green Tea, Yerba Mate Extract, Guarana Extract, Green Coffee Bean Extract, and Gotu Kola Extract. This is a precise combination of eight types of caffeine and sourced specifically to create a smooth, extended energy curve while effectively eliminating the jitters of caffeine and the “caffeine crash” accompanying most highly caffeinated products. Prepare yourself for what’s next, blasting yourself into a gym session fueled by a blend of caffeine from 8 sources: COCOABUTEROL® Cocoa Alkaloid Extract (Theobroma caco L.) Cocoabuterol® is a new dietary weight loss supplement to activate thermogenic fat burning within the body while boosting your energy and mood. The natural alkaloids in Cocoabuterol® can significantly increase cAMP via beta-adrenoceptor which activate thermogenic fat burning and muscle building functions. This translates to fat burning PLUS support for the building of lean muscle tissue without the side effects. Compared with caffeine, Cocoabuterol® doesn’t have the edginess often associated with caffeine while it lasts longer and while similarly balancing the onramp and offramp of caffeine into your body, enhancing caffeine’s most desirable qualities. Because Cocoabuterol® acts to smooth out the caffeine curve, you’re unlikely to experience the shakes and jitteriness associated with excessive caffeine consumption. CAFFEINE ANHYDROUS Commonly used as a fast-acting energy source, Caffeine Anhydrous has been used in many of the best pre-workouts and energy-based products alike. This ingredient will assist with mental alertness as it stimulates the central nervous system, enhancing your energy output in a short time. DI-CAFFEINE MALATE What makes Di-Caffeine Malate so interesting is the time-released energy production that is so heavily influenced and reflected by this ingredient. Like caffeine, this specific ingredient helps improve energy levels and mental focus. Best of all, Di-CM helps endurance and stamina, plus the energy to combat fatigue during your workout. THEOBROMINE Theobromine is similar in structure to caffeine and falls into the same class of methylxanthine compounds. Although theobromine is similar in structure to caffeine, it’s only about 1/10th the strength of caffeine. Theobromine is somewhat unique in that compared to most stimulants, it's actually been shown to decrease blood pressure. It has mild vasodilating properties, similar to the amino acid Arginine, and is believed to increase blood flow. OTHER SOURCES OF CAFFEINE Caffeine sourced from Green Tea leaves, Yerba Mate Extract, Guarana Seed Extract (Paullinia cupana), African Snakeroot (Rauwolfia vomitoria)(leaves), Green Coffee Bean Extract (Seed), and Gotu Kola Extract (Centella asiatica).
Only the upper tier of pre-workouts and sports nutrition products will feature the nootropic alkaloid Huperzine-A to enhance cognitive function levels and neuroprotective properties. Huperzine A is an alkaloid purified from club moss (Huperzia serrata) and boosts focus while training.
Choline is a molecule mostly used for either its nootropic or cognitive boosting properties (turning into acetylcholine, the learning neurotransmitter) or as a liver health agent, able to reduce fatty liver buildup. Choline is an essential nutrient that is the building block for phosphatidylcholine cellular membranes and the precursor to acetylcholine, which is an important neurotransmitter involved in memory, muscle control, metabolism and transport of lipids.
Citrulline is a proven nitric oxide (NO) pump ingredient, delivering sleeve-stretching muscle pump and other great performance-enhancing benefits. Citrulline plays a role in ATP production when your muscles require additional energy. It also helps buffer the buildup of ammonia in muscle, which reduces exercise fatigue and increases workout endurance! Citrulline has an impact on both the phosphagen and glycolytic energy systems. It can modulate enzymes involved in glycogen breakdown, glycogenolysis, and enzymes that convert glucose to ATP (glycolysis). This action shifts muscle from aerobic to anaerobic metabolism and reduces the rate at which the body uses up ATP and phosphocreatine. This means more energy is available to the muscles for longer periods of time!
There’s a reason so many energy drinks feature Taurine, namely due to its ability to reduce the acute effect felt by both the jolt of caffeine entering the body and to mitigate the jitteriness. Many consumers of Taurine will agree that it increases the enjoyment of the effects of caffeine. Additionally, it's considered to be an “osmotic agent”, meaning that it draws water into cells. And when cells have a higher water content, they tend to produce more effects related to recovery and anabolism. Taurine is often included with fat-burning supplements because it can help reduce the side effects of muscle cramping.
N-Acetyl L-Tyrosine (NALT) is an acetylated derivative of the nonessential amino acid, L-Tyrosine, that is used in the process of protein synthesis. Tyrosine is also a precursor of several chemicals and neurotransmitters such as dopamine and norepinephrine. NALT may also assist in exercise recovery and may help with maintaining healthy weight in already healthy individuals when taken in conjunction with a healthy diet and exercise.* NACT may help in maintaining a healthy mood, contribute to a calm feeling of overall well-being in already healthy individuals, and aid cognition.*
Raw Synephrine HCL powder is a naturally occurring alkaloid chemical compound found in plants and extracted for use as a supplement. Synephrine is sometimes referred to as ‘bitter orange’ as it is derived from small oranges. In actual fact, it is naturally found in the rind of the orange, which is why it is known as “bitter orange”. Bitter orange is currently used for a number similar issues as well as some more modern-day troubles like weight loss and as an aid in the battle against athlete’s foot. Synephrine hcl enhances the body’s utilization of carbohydrates by producing more energy in the form of ATP. It facilitates cellular uptake of glucose in muscle cells, as well as glycogenolysis, gluconeogenesis, glycolysis, and oxygen uptake. The use of Synephrine hcl will also inhibit the activation of NF-kB, this substance is key in causing inflammatory response in the body. Studies also show that synephrine hcl powder binds to β3-adrenergic receptors, resulting in an increase in the body’s ability to break down fats.
