King Cobra Ingredients



  • Trixanthin Complex (375mg)

    King Cobra’s energy matrix is bolstered by a trifecta of methylxanthine compounds including Ilex Guayusa, Green Tea and Theobroma Cacao -- three powerful ingredients which stimulate the CNS, increase motivation, and kickstart fat loss.

    Blackstone has standardized the complex to yield 200mg caffeine, 45mg EGCG, 25mg each Theobromine and Theophylline.

    • Ilex Guayusa

      Ilex Guayusa is a plant native to South America traditionally consumed by Ecudorian and Peruvian natives as a morning stimulant. The plant is rich in both caffeine, theobromine, and chlorogenic acids, lending both immediate and long-lasting energy to your day as well as accelerated fat burning.

    • Green Tea Extract

      Green tea is known far and wide for its health-promoting properties, particularly in regards to cardiovascular health. But, the potent leaves of Green tea is also loaded with all kinds of polyphenols and catechins, such as EGCG, which has been shown to greatly enhance lipolysis (a.k.a. fat burning)!

    • Theobroma Cacao

      Theobroma Cacao, a.k.a. the cacao or cocoa tree, is the tree from which cocoa nibs, cocoa powder, and chocolate are derived. The tree is also rich in xanthine compounds theophylline and theobromine which provide smooth, long-lasting energy so you feel alert and upbeat even when on low calories.

  • Eria Jarnesis (150mg)

    Eria Jarensis is one of the hottest ingredients around these days and for good reason -- it's LOADED with all sorts of PEA alkaloids, including the highly sought after N-phenethyldimethylamine.

    Eria Jarensis is known for the prolonged “euphoric” feeling it gives users, that just never seems to end. If you’ve tried this ingredient before, you know it’s benefits, but you’ve never experienced the power of Eria when used alongside DMAA as it is here!

    Mood enhancement, focus, and energy just got ramped up to a whole new level!

  • Triple-Heat Thermogenic Intensifier (300mg)

    • Paradoxine®

      King Cobra is more than just a cocktail of stimulants though, it’s also loaded with several proven non-stimulant fat loss agents led off with Paradoxine®.

      Paradoxine® is the industry-leading Grains of Paradise extract used for its ability to increase thermogenesis, energy expenditure and enhance mobilization of fat stores from brown adipose tissue (BAT).

      This is one of the few proven non-stim fat loss ingredients on the market, just be wary that you’ll be getting some serious sweats with this one!

    • Capsimax®

      Capsimax® is another non-stim, temperature spiking ingredient included in King Cobra.

      Extracted from chile peppers, Capsimax is a patented extract of capsaicin, the potent alkaloid in cayenne peppers, jalapenos, and other chiles that gives them their notable tongue-numbing heat. Capsimax is a proven compound to decrease appetite and rev up your metabolic rate, so you burn more calories during the day and experience faster weight loss!

    • BioPerine®

      Typically included for its bioavailability-boosting properties in supplements, BioPerine® also is an effective fat loss and thermogenic agent thanks to piperine, the pungent alkaloid present in black pepper that gives black pepper its bite.

  • Erythropalum scandens (50mg)

    Found throughout Southern Asia, Erythropalum Scandens is an herb traditionally used for its healing qualities, due to the numerous bioactive compounds present in its leaves. Researchers have thoroughly studied the plant and found that several of the alkaloids are excellent mood and energy boosters including 2-Phenethylamine, N-Benzyl-2-phenylethylamine, and N,N-Diethyl-2-Phenylethylamine which have a greater half-life in the body than regular PEA.

    If you thought Eria Jarensis gave a noticeable mood boost, you’ve got even greater mood enhancement and energy coming courtesy of this Oriental herb!

  • 1,3 Dimethylamylamine HCl (45mg)

    The king of all stimulants is back at Blackstone Labs!

    DMAA is an aliphatic amines renowned for its stimulating, focus-boosting, and mood-elevating effects. It’s quite potent in its own right, but when combined with caffeine, Eria Jarensis, and the other stimulants in King Cobra, you’ll experience a renewed sense of energy and euphoria like never before!

    DMAA is also an incredible appetite suppressant, which helps you stay on track with your diet and avoid those awful hunger pangs that pop up during the day.

  • Citrus Aurantium (42.5mg)

    Also known as bitter orange, Citrus Aurantium quite familiar to the world of fat burners -- it’s loaded with several alkaloids that function as beta receptor agonists, namely Synephrine. Blackstone Labs has standardized is Citrus Aurantium extract to 25mg synephrine, a powerful beta-2 and beta-3 receptor agonist proven to stimulate lipolysis in the body.

    In other words, synephrine helps shift your body into “fat burning” mode by burning up freed fatty acids for energy and sparing your glycogen stores for when they’re really needed.

  • Yohimbe Extract (22mg)

    To bring the whole fat burning package together, King Cobra includes Yohimbe extract standardized to Yohimbine, alpha-yohimbine, and 11-hydroxy yohimbine.

    Yohimbine (and its various forms) are powerful CNS stimulants that suppress appetite as well as function as alpha-2 receptor antagonist, which helps prevent fat storage in the body.

    So, not only does King Cobra contain ingredients that help burn fat, like Synephrine and Paradoxine, but includes one of the most powerful fat blockers around to provide a multi-tiered approach to fat loss.

    This is what makes King Cobra the king of fat burners!
