Rhino black leaves no stone unturned, with no confusing ingredients or hidden quantities.

Muscle Sport International have designed the most optimal pre-workout with mood, energy and performance being their focus.

Expect, skin splitting pumps, razor-sharp focus, extreme energy and a noticeable reduction in fatigue.

Step up and charge through your workout with Rhino Black.


Citrulline Malate

Citrulline malate is both a natural precursor to arginine production. Nitric oxide release as well as a potent aerobic endurance-enhancing agent. Dosing with greater than 4g of Citrulline Malate has been shown to reduce exercise-induced fatigue. It can also improve blood flow and enhance the re-synthesis of valuable high octane energy.


Agmatine supplementation enhances nitric oxide release while simultaneously preventing the breakdown of circulating levels by inhibiting pump preventing NO Synthase. Using Agmatine around training has also been shown to reduce the pain response to exercise.

Beta Alanine

Beta Alanine is the primary rate limiting amino acid responsible for enhancing intramuscular Carnosine and has been shown to enhance the hydrogen ion clearance potential of the muscle, resulting in an increase in endurance capacity and lactate threshold.

Creatine Magnesium Chelate (CMC)

CMC is a fortified creatine substance attached to magnesium in order to enhance its efficiency of uptake into the muscle cell, allowing maximum ATP production and enhanced strength and power.

Muscle Stimulation Complex

Combining caffeine, CDB Choline and Tyrosine has been shown to clinically enhance the benefits of all three ingredients.

Known for its assistance in the natural production of adrenaline, Tyrosine when coupled with caffeine is linked to enhanced reaction time, reduced perceived fatigue and an increase in focus.

Coupled with choline, which is known as the learning neurotransmitter, this muscle stimulation complex provides optimal local and peripheral energy release, natural mood enhancement and improved cognitive function.


Hordenine is a supportive adrenergic stimulant but more importantly has been linked to preventing the re-uptake of important neurotransmitters, causing an increase in time of effect and no crash.

Final Thoughts

Rhino Black by Muscle Sport International is hands down one of the most nutrient-packed, clinically dosed, transparent products currently on the market.

For first time users, start with a half scoop but for maximum benefits, utilising a full scoop will enhance performance like you’ve never experienced before.
