frequently asked questions

Q: Can I take ADRENOCHARGE while taking a pre-workout or thermogenic with stimulants in it?
A: No. To effectively reset your receptor systems and assist in adrenal fatigue support, ADRENOCHARGE should only be taken once you complete a cycle of taking a pre-workout or thermogenic with stimulants.†

Q: Can I take ADRENOCHARGE for general adrenal fatigue support?
A: Yes. ADRENOCHARGE contains key ingredients which battle the effects of stress, cortisol, and adrenal fatigue.†

Q: Will ADRENOCHARGE work after taking products from companies other than Gaspari Nutrition?
A: Yes. ADRENOCHARGE is formulated to address the physiological effects of adrenal fatigue and stimulant use regardless of brand.†

When was the last time you really felt your pre-workout without having to add an extra scoop? Ever taken a fat burner and said to yourself "man this stuff is weak." If you answered "yes" you're not the only one out there. Most of us who take supplements know that eventually no matter how good they are, their stimulant effects eventually wear off. You may have the strongest pre-workout ever, but you're still susceptible to this. The researchers at Gaspari Nutrition recognized this so instead of telling you to "add another scoop" or "add another serving", we focused on how to solve this issue with a real solution.

As always, CEO and hall of fame bodybuilder Rich Gaspari put the pressure on his product development team to solve this issue which seemingly affects the majority of stimulant supplement users. After a lot of trial and error they finally came up with a clinical strength solution backed by real research. That solution is called ADRENOCHARGE. Let us explain how it works so you can regain that feeling of intensity from your supplements in rapid time.†

A Look At the Ingredients





This is a potent extract based off of thousands of years of use in the Far East as a health tonic. However, newer research has demonstrated that cordyceps has energy enhancing abilities without the use of traditional stimulants. In return, it does not interact with the same adrenal fatigue inducing receptor systems which can run you down or desensitize you to the likes of caffeine. Instead, it is used to support athletic performance by strengthening the immune system and energy levels.†



Innovation is something we excel at which is why we're proud to be the first company to use this patented combination of phosphatidlyserine and phosphatidic acid. This potent combination is clinically proven to reduce stress hormone levels in response to stress tests. It does this by exerting a unique effect on the hypothalamus pituitary adrenal axis which in turn controls stress hormones such as cortisol.


Often times, when you don't have your morning coffee you can get cranky. Or you may be the type of person who just can't train if you forget your pre-workout. Then you're cranky because you didn't train. Either way, not having stim ulants can slow you up mentally. Rhodiola has a wealth of research to show it can help with mood and enhance natural energy levels without stimulants.†


Caffeine plays a strong role in most stimulant supplements and one of its effects is increasing adenosine receptor expression. What this means is that the more you take, the more adenosine receptors you have in your nervous system which can contribute to diminishing effects. Adenosine monophosphate may in turn help down regulate adenosine receptor expression as it increases adenosine levels.†


If you check any regular multivitamin you'll most likely see a form of B5 called pantothenic acid. Pantethine is considered the bioactive form of pantothenic acid but is also responsible for fatty acid metabolism via Coenzyme A activation which helps with natural energy production in the mitochondria.

*When combined with a proper exercise and nutrition program.

Top Secret Cardio Igniter 35 serving

The Cardio Igniter is a new category of pre-workout performance enhancing supplement that focuses on promoting aerobic capacity and burning fat.* If your goal is to support your best performance and get ripped while doing it, the Cardio Igniter™ is the product that can help.*

Cardio Igniter™ is designed to:

Help boost aerobic capacity*
Help protect and stimulate lean muscle mass*
Help accelerate fat loss*
Help support concentration and stave off boredom*
Provide stamina-boosting, long-lasting energy and endurance*
Provide key electrolytes that help delay fatigue and maintain mental alertness*

The Cardio Igniter™ utilizes a novel physiological technique that not only helps increase endurance levels but also supports fat burning.*

Skeletal muscle relies mainly on carbohydrates and fat oxidation to meet energy needs during exercise. Numerous scientific studies have suggested that increasing the intensity of exercise leads to a faster utilization of carbohydrates.* As carbohydrates are used, glycogen is depleted; this glycogen depletion is the limiting factor for the continuation of strenuous exercise.

Traditionally, athletes have tried to slow down the depletion of glycogen by consuming high amounts of carbohydrates before and/or during strenuous exercise. Although effective, there is another way to improve endurance: utilize fatty acid oxidation as an energy source.* Research suggests that enhancing fatty acid oxidation during exercise promotes a reduced rate of glycogen degradation, resulting in an improved endurance capacity.*1 Guided by the latest scientific data and research, Cardio Igniter™ has been designed to promote fatty acid oxidation.*

Pre-Workout - Cardio Igniter™ is great to use prior to any high intensity training where you need maximum aerobic capacity such as cross training, HIIT (high intensity interval training) and LISS (low intensity steady state).* Cardio Igniter™ helps prioritize fat as an energy source during exercise and provides both anti-catabolic and anabolic (lean mass potentiating) elements. Burn fat while you work out!*

Post-Workout, Before Cardio - Many athletes perform resistance training prior to cardio (aerobic activity), while glycogen stores are high and energy levels are strong. Cardio Igniter™ is an excellent solution post resistance training because it helps to fuel the anabolic window and protect lean mass, while at the same time priming the body for aerobic activity and fat burning.* Don't miss the window!

Before Stand-Alone Cardio - Help prime your body and mind for maximum fat
burning and aerobic intensity with the Cardio Igniter™.* Never do cardio without it!

Before Athletic Activity - Cardio Igniter's ability to help support energy, improve
endurance, and enhance mental focus is a huge benefit to anyone performing athletic
activities.* It is very beneficial for aerobic oriented sports such as crossfit,
soccer, basketball and martial arts. Burn fat while you perform!*

Xtend 90 Servings | Scivation

What is Xtend?
A: Xtend is the ultimate, sugar-free, BCAA-containing drink mix to be consumed during exercise (intra-workout). Whether you're a physique athlete, strongman, powerlifter, traditional athlete (e.g., football, basketball, baseball, soccer, etc), endurance competitor, or just looking to significantly change your body composition through resistance training and nutrition, Xtend is ideally formulated to maximize training intensity and support your goals.* Xtend was the first and has become the most well-recognized and used intra-workout catalyst product because it not only works... but it tastes great too! Xtend contains an incredible:
  • 7000 mg of BCAAs in an ideal 2:1:1 ratio of Leucine:Isoleucine:Valine
  • 3500 mg of Leucine
  • 2500 mg of Glutamine
  • 1000 mg of Citrulline Malate
  • 1171 mg of Electrolytes
  • 640 mcg of Vitamin B6
  • And, ZERO Carbohydrates or Sugar
Xtend was recently reformulated to dramatically improve taste and ingredient solubility - Xtend is now spoon-mixible - and to provide added functionality for workouts or events under the most grueling of conditions. Xtend is available in 6 mouth-watering, refreshing fruit flavors to make every workout an incredible one.

Q: Who should use Xtend?
A: Xtend was designed to be used effectively by anyone, male or female, who want to perform at their best - from serious athletes to anyone that's just serious about performance or changing their physique. Though ideal for strength or bodybuilding training, or for persons on a reduced carbohydrate diet, Xtend can also be used very effectively in a "bulking phase" or by endurance athletes during training and competition. That is, Xtend works whether it's used as formulated and indicated, or whether you choose to combine Xtend with supplemental carbohydrates based upon performance needs and duration.

Q: When's the best time to consume Xtend?
A: Two university studies suggest that Xtend is significantly effective at increasing muscle mass and strength, and reducing body fat when consumed during exercise or immediately prior to and after training.* It's recommended that you begin consuming Xtend immediately prior to, and continue sipping on Xtend throughout your training or competition. Many users also report significantly improved gains when Xtend is consumed immediately upon waking-up in the morning and/or sipping on Xtend throughout the day.

Q: How much Xtend should I consume for it to be most effective?
A: For best mixing results and taste, pour 8 fluid ounces of filtered water into a shaker cup. Add 1 scoop of Xtend. Cover or close the shaker cup. Swirl the shaker to create a vortex effect and draw the Xtend powder into solution. Then, once the Xtend powder has fallen into solution, shake vigorously for about 25 shakes. Enjoy! For endurance athletes that may add Xtend to their hydration pack, it is recommended that Xtend be mixed in a shaker cup or pitcher and then poured into the hydration pack (as opposed to mixing directly within the hydration pack, as doing so may cause the hydration tubing to become blocked). NOTE: If you find that some of the BCAA material settles at the bottom of the shaker cup, you may not have used the correct dilution ratio of 1 scoop of Xtend per 8 fluid ounce of water.
Up to 200 lbsOver 200 lbsUp to 125 lbsOver 125 lbs
2-3 Scoops per day3-4 Scoops per day1-2 Scoops per day1-3 Scoops per day

Other results you can expect from using Xtend include:
  • Increased Exercise Training Volume (More Volume/More Total Work = Greater Adaptation or More Muscle)*
  • Increased Muscle Protein Synthesis*
  • Reduced Muscle Protein Breakdown*
  • Increased Muscular Endurance*
  • Increased Energy & Endurance Capacity*
  • Improved Blood Glucose Disposal & Insulin Response*
  • Increased Power Output*
  • Increased ATP Synthesis/Resynthesis*
  • Increased Nitric Oxide (NO)*
  • Delayed Onset of Muscle Fatigue/Increased Time to Exhaustion*
  • Improved Neuromuscular Responsiveness & Recovery*
  • Improved Hydration*
Q: How fast will I see results from using Xtend?
A: Most Xtend users report an immediate, acute response during training. Variables such as training volume, reduced fatigue, and increased muscular endurance and power output are common to first-time Xtend users.* For body composition and strength changes, Xtend studies support significant improvements in as little as 8 weeks.*

Q: Is Xtend safe?
A: Not only do each of the individual ingredients used in Xtend have an incredibly high dosing threshold of safety and many years of validated clinical trials to support safety across a wide range of consumers, but Xtend did not adversely affect any measures of safety in either of the two clinical studies in which it was used chronically and at high doses for up to 10 weeks. Additionally, each batch of Xtend undergoes rigorous quality assurance and analytical testing to validate ingredient purity and potency, and is blended and packaged in an NSF for Sport® certified facility to ensure no banned substances are inadvertently introduced into the manufacturing process while producing Xtend.

Q: How does Xtend work?
A: Xtend is formulated with a precise PentActive blend of key ingredients, synergistically involved in cellular processes to optimize muscle performance and response*:
  • Stage 1: 7000 mg of BCAAs, in a 2:1:1 ratio of Leucine:Isoleucine:Valine is used to provide metabolic energy while you train, as well as to stimulate muscle protein synthesis.*
  • Stage 2: 2500 mg of Glutamine is used to increase extracellular concentrations of Glutamine, which helps to promote muscle intracellular BCAA metabolism down the correct energy and protein synthesis pathways via the BCAA aminotransferase enzyme.*
  • Stage 3: 640 mcg of Vitamin B6 serves as the rate-limiting cofactor involved in optimal BCAA aminotransferase reactions.*
  • Stage 4: 1000 mg of Citrulline Malate can help support rapid ATP turnover and lactate reabsorption to support higher training volumes at a given exercise intensity.* Citrulline also serves as a secondary signal to stimulate muscle protein synthesis, most likely arising from its ability to promote increased blood flow via increase nitric oxide (NO) and/or improving the energy state of a cell by promoting lactate reabsorption.*
  • Stage 5: 1171 mg of an extensively studied Electrolyte blend, consisting of Trisodium Citrate Dihydrate, Potassium Chloride, and Sodium Chloride, help to optimize muscle contractile function and promote cell hydration under the most brutal of conditions.*
Q: How does Xtend compare to other products?
A: In both 8-week & 10-week clinical trials, under no or weight-reducing calorie restricted diets, respectively, Xtend has significantly outperformed Whey Protein, Carbohydrates and a 4:1 (Carb-to-Protein) sports beverage on measures of lean body mass, body fat, upper- and lower-body muscular endurance, and upper- and lower-body strength.* Within the physique and anaerobic sports nutrition industry, competitive products are either under-dosed, contain irrelevant ingredients included more for a label effect than a physiological one, or are so ignorantly formulated as to wonder what species' metabolism the company's R&D personnel believes to be their core audience. During exercise beverages for the endurance world, on the other hand, still depend too heavily on simple carbohydrates or, when amino acids are included, generally use low doses of a whey protein concentrate that yield only a fraction of the key amino acids and introduce unnecessary lactose and fat into a high-performance environment.

Q: Are there any other products that will help improve the results I achieve when using Xtend?
A: Xtend was formulated, and then recently reformulated to remove the need for additional ingredients while you train or compete. However, Xtend was explicitly formulated to contain no carbohydrates or sugar so that you could dictate how you may want to manipulate your carbohydrate needs based upon your training cycle or duration. Therefore, when carbohydrates are desired, combine Xtend with up to 0.45 g of carbohydrate per pound of body weight, per hour of exercise. When carbohydrates are added, increase the amount of water used per serving so that the finished formula concentration is easily digestible during exercise

The human equivalent doses for the effective and ineffective (over-)dose are 4mg/kg and 8mg/kg. If we assume that the results are applicable to men, as well, this would mean that a daily dose of 320mg of Tongkat Ali root extract would increase your testosterone and decrease your estrogen levels, while a dosage of 640mg per day would not.
