Musclesport Rhino Black Series Pre-Workout nutritional information

Muscle Sport is a new brand which is fast earning a reputation as one of America's highest quality supplement brands and in Rhino Black they have unleashed a new pre-workout which we believe could be set to become one of the most popular ones around thanks to its combination of high energy, nootropic and pump focused ingredients.

With 400mg of Caffeine and an open transparent label that lets users judge for themselves how much of each ingredient they require, Rhino Black brings a lot of energy to your workouts with the Caffeine dose supported by the amino acid L-Tyrosine, a well-known amplifier of other stimulants' effects as well as nootropics and focus enhancers in CDP Choline and Hordenine.

Rhino Black is more than just a stimulant frenzy though as it also includes study validated 3.2g dose of Beta Alanine which means just one serving gives you the dose of Beta-Alanine proven to enhance endurance and delay fatigue, especially during higher rep activity.

As if all that was not enough, Muscle Sport have included some great nitric oxide boosters with high doses of Agmatine, Nitrosigine and a whopping 6g of Citrulline Malate per scoop.

When you add in 1.5g of Trimethylglycine and 2g of Magnesium Creatine Chelate, both of which will further support faster gains in strength and endurance it further sets this product apart in a crowded pre-workout field.

Quite simply, we do not think there is another product which combines energy and pumps quite like Rhino Black. While it is a relatively unknown brand we expect that in time Muscle Sport is a name you will be hearing a lot more.

Check out the ingredient profile below


Citrulline Malate

Citrulline Malate is a non-essential amino acid that eventually converts to nitric oxide. Nitric oxide is a vasodilator that can help to lower blood pressure and improve blood flow to both organs and muscles.

  • Studies have shown that Citrulline Malate enhances exercise tolerance by reducing levels of blood ammonia and lactate that are typically elevated during strenuous exercise.
  • This ingredient will allow you to train with less rest in between sets and elevate your endurance capacity.
  • A recent research study found individuals who consumed citrulline malate for 15 days were able to increase ATP production during exercise by 34% and improve phospho-creatine resynthesis after exercise by 20%.

TrimethylGlycine (Betaine Anhydrous)

Betaine helps to support methylation reactions in the body which include but are not limited to liver detoxification and neurotransmitter production.

  • It has been shown to increase energy levels as well as muscle strength and recovery. Betaine's effects on the neurotransmitters can help to increase the effectiveness of the “mind-muscle” connection.
  • Betaine works synergistically with Choline (another ingredient found in RHINO BLACK).
  • A study conducted by the University of Connecticut found that individuals supplementing with 1.25 grams of betaine twice/daily increased bench press power by 20%.

Agmapure (Agmatine Sulfate)

Agmatine Sulfate helps improve nutrient partitioning which leads to an increase in muscle glycogen (carbs stored in muscle tissues) which then leads to more water retained within the muscle. This creates a fuller look to the muscles and a greater pump while hitting the iron.

  • Agmatine Sulfate also increases NO production by working as a competitive inhibitor of the enzyme NO Synthase.
  • There are studies to suggest that the nutrient partitioning effects of agmatine sulfate are possibly due to its ability to increase the insulin response to carbohydrates. This could be further explained by the increased blood flow to the muscle that occurs with increased NO production.
  • LH and GH levels have been shown to be increased through the effects of Agmatine Sulfate and its possible effects on the hypothalamus.
  • Agmatine has also been shown to manipulate pain receptors which may allow you to train past normal pain thresholds.


Taurine has a myriad of benefits. From helping the body to metabolize fat, improving insulin sensitivity, raising testosterone levels, as an antioxidant, higher performance and quicker recovery during athletic training and increasing cardiovascular health… it goes without saying that Taurine is a great ingredient to have in your wheelhouse

  • Zhang et al. (2004) found that individuals who supplemented with taurine for 1 week before an exhaustive exercise bout significantly improved time to exhaustion, VO2 max, and maximal workload. It also decreased exercise-induced DNA damage.

Nitrosigine (Arginine Inositol Silicate)

Arginine (Nitrosigine) is a precursor to nitric oxide and expands blood vessels to optimize blood flow. Silicate is contained within the walls of the arteries to help maintain their structural integrity.

  • These ingredients work in synergy to help increase the blood flow and the structural integrity of the artery walls.
  • Preclinical data has shown that Nitrosigine is superior to standard arginine… with 2x the blood flow in vasodilatation response.


Ornithine, when bound by salt at the molecular level to Orotate (orotic acid), is much more bio-available than in its HCL or free form.

  • Ornithine Works in synergy with Arginine in the metabolism of waste caused by intense exercise.
  • By increasing Nitric Oxide production and decreasing waste – you are able to train longer and support greater results
  • A 2008 study conducted by Sugino et al. discovered supplementation with ornithine was able to reduce perceptions of fatigue to 52% of placebo on a prolonged endurance test and was able to reduce ammonia accrual during exercise.

Beta Vulgaris

Beta Vulgaris (beets) is extremely rich in nitrates and other ergogenic compounds. These components have been systematically proven to improve workout performance.

  • Nitrates in beets have been shown to improve blood flow and exercise efficiency.
  • Betalains in beets improve oxygen-carrying capacity and endurance.
  • Supplementing with beet juice has been shown to reduce the energy (ATP) cost of every muscle contraction, leading to improved workload and sustained performance.


3-Aminopropanoic Acid

3-Aminopropanoic acid is a precursor to carnosine that is better for improving muscle carnosine concentrations than carnosine supplementation itself. Carnosine acts as an intracellular buffer, neutralizing acids and bases.

  • Improves high-intensity anaerobic performance, such as high-rep sets and repeated sprints (HIIT).
  • A study by Van Thienen et al. (2010) found 3-aminopropanoic acid supplementation to improve power output by 11.5%
  • Long term supplementation with 3-aminopropanoic acid has been observed to increase lean mass gain while decreasing fat mass.

Highly Branched Cyclic Dextrin

Cyclic Dextrin is a clinically studied carbohydrate that is rapidly absorbed and provides fuel (glycogen) to working muscles.

  • In cyclists supplementing with either HBCD or maltodextrin, HBCD was shown to dramatically enhance performance vs. the same quantity of maltodextrin.
  • During HIIT, supplemention with HBCD extends time to exhaustion by 70% vs. glucose, greatly enhancing cardiovascular gains and fat loss potential of training.
  • Athletes consuming HBCD instead of their normal sports drink report fewer gastrointestinal disorders and side effects.
  • Use of HBCD during athletic events has been observed to reduce stress hormone and inflammatory cytokine response, leading to improved performance and recovery.

Creatine MagnaPower® (Creatine Magnesium Chelate)

By combining magnesium to the creatine mixture in this compound – it allows (in a similar fashion to COP) the creatine to be absorbed and utilized for anabolic processes and prevents conversion to creatinine through the process of cyclization.

  • Creatine MagnaPower pulls together both creatine and magnesium for the most effective ATP synthesis.
  • The ISSN (International Society of Sports Nutrition) position stand on creatine monohydrate (CM) found that short-term CM supplementation has been reported to improve maximal power/strength (5–15%), work performed during sets of maximal effort muscle contractions (5–15%), single-effort sprint performance (1–5%), and work performed during repetitive sprint performance (5–15%). Long-term CM supplementation appears to enhance the overall quality of training, leading to 5 to 15% greater gains in strength and performance.



L-Tyrosine helps to activate metabolic pathways that produce the hormones epinephrine and norepinephrine - which are typically produced during moments of stress on the body and provide a boost in the terms of a “fight or flight” scenario.

  • Epinephrine and norepinephrine are depleted quickly during these moments of stress due to a lack of L-Tyrosine.
  • The addition of this amino acid to RHINO BLACK will help give you an extra PUSH and can make a big difference to help you FIGHT through your workouts and plateaus.
  • Hoffman et al. (2010) research results indicate that acute ingestion of supplement including L-tyrosine and anhydrous caffeine can maintain reaction time and subjective feelings of focus and alertness to both visual and auditory stimuli in healthy college students following exhaustive exercise.

Tri-Caffeine Matrix (Caffeine Anhydrous, DiCaffeine Malate, Caffeine Citrate)

This blend of caffeine helps to provide effectively dosed stimulation for your training and not keep you up all night long.

  • It is also formulated to help fight that horrible crash you might experience with stimulated laden pre-workouts.
  • Multiple studies have confirmed can improve muscular endurance and power, focus and cognitive performance, and improve energy levels. Caffeine has also been shown to have a thermogenic effect (heating/calorie burning) at rest and may increase the use of fats for fuel during exercise.
  • Doherty and Smith performed a meta-analysis of caffeine's effects on perceived exertion and found a 5.6% decrease in RPE (rating of perceived exertion) during exercise.  This means exercise may feel easier at higher effort levels when supplementing with caffeine.

Choline Complex (CDP Choline/Choline Bitartrate)

Choline is an essential nutrient for brain health and synaptic plasticity.

  • Choline improves structural integrity, signaling capacity and the fluidity of neural membranes. It’s estimated that close to 90% of the population does not get the recommended amount of choline daily.
  • It has been shown that a dose of 500mg of Choline can boost focus, mood and concentration abilities.
  • This is tantamount to pushing through your workout. Utilizing this effectively dosed compound, you will be able to focus on taking less rest or being distracted during your training. Giving your 110% will really be your 110%.
  • A study conducted by Sun et al. (1999) reported that subjects who supplemented with choline for 4 weeks improved learning performance and memory compared to a placebo group.


Extracted from the roots of sprouted barley, hordenine has an adrenaline-like effect stemming from its ability to release noradrenaline.

  • This increases heart rate and blood flow.
  • The adrenaline effect is long lasting and does not fade early in your workouts. This will create a boost in athletic performance throughout your entire workout.
  • Hordenine may also increase peripheral blood flow volume and have a positive inotropic effect (increases the strength of contraction) upon the heart.
