Unleash your inner beast with the Alpha Lion Super Burn Stim-Free pre-workout. This limited-edition formula is crafted for athletes who demand peak performance without the jitters of stimulants. Each scoop of Super Burn Stim-Free is packed with a powerful blend of ingredients designed to enhance your endurance, focus, and fat-burning capabilities.

Flavour Profile:Dive into the cosmic taste of Galactic Blue Coconut, a unique blend that tantalizes your taste buds and provides a refreshing twist to your workout routine.

Superhuman Performance Matrix:

  • L-Citrulline: This non-essential amino acid is converted into L-arginine in the kidneys, which then boosts nitric oxide production in the body. Enhanced nitric oxide levels lead to vasodilation, which means your blood vessels widen, improving blood flow. This can deliver more oxygen and nutrients to your muscles during exercise, potentially reducing fatigue and increasing endurance.

  • Beta-Alanine: As a precursor to carnosine, beta-alanine can help buffer acid in muscles, increasing physical performance in the 60 240-second range. Carnosine acts as an intracellular buffer, countering the pH drop that occurs with high-intensity exercise that leads to fatigue.

  • L-Taurine: Often found in energy drinks, taurine is an amino sulfonic acid essential for several metabolic processes. It’s thought to have antioxidant properties and can aid in electrolyte balance, which is crucial during intense workouts.


  • Superhuman Stim-Free Energy & Focus Matrix:

  • Choline Bitartrate: This compound is a source of choline, an essential nutrient that plays a role in several metabolic pathways, including neurotransmitter synthesis. It’s linked to cognitive functions such as memory and muscle control.

  • L-Tyrosine: This amino acid is a precursor to several important neurotransmitters like dopamine, epinexxrine, and norepinexxrine. These compounds are vital for brain function and can influence mood, motivation, and response to stress.

  • SantEnergy Nu: Extracted from Eriodictyon californicum, this natural ingredient is believed to support energy and mental focus. It may act as an antioxidant and help delay fatigue.

  • Alpha GPC: This choline compound naturally found in the brain is also a parasympathomimetic acetylcholine precursor, which may enhance the release of the neurotransmitter acetylcholine involved in learning and muscle contractions.

  • Alpinia galanga extract: Also known as Thai ginger, this plant extract is suggested to have cognitive-enhancing properties and may act as a stimulant.


  • Superhuman Advanced Thermogenic Matrix:

  • MitoBurn : This branded ingredient is L- -Aminoisobutyric Acid, which is said to function as an exercise mimetic, meaning it may induce some of the same effects as exercise on fat metabolism.

  • Sensoril : An Ashwagandha extract that could help lower cortisol levels, enhance mental clarity and concentration, and reduce stress-related food cravings.

  • CaloriBurn GP : Sourced from the seeds of the Aframomum melegueta plant, also known as grains of paradise, this extract is associated with thermogenesis and increased metabolic rate.

  • Black Pepper Extract: Black Pepper Extract contains a molecule called piperine, which has been shown to enhance the digestive tract’s absorption of various nutrients and may also have a thermogenic effect.

  • ProGBB : Known as the “Super Carnitine,” this molecule serves as a precursor to L-carnitine and is believed to increase its production, enhancing fat metabolism and energy levels.


  • Dosage:



    • Serving Size: The standard serving size is one scoop, which is 15.2 grams.
