Rhino Black Series is a pre-workout made by MuscleSport.
It’s designed to improve your workouts by increasing your performance, focus, and energy levels.
MuscleSport is an American supplement brand, which was founded in 2008.
Citrulline is a nitric oxide booster.
Nitric oxide is responsible for the temporary expansion of blood vessels, which can improve blood flow and “the pump” (1).
The effective dose is 6-8g.
Betaine is a compound found in sugar beets.
Research shows that it may improve power output, and possibly lean body mass (2).
The effective dose is about 2.5g.
Agmatine is another nitric oxide enhancer that’s shown promise for improving pumps, and possibly mood levels too.
Further research is needed, but it’s currently a very common ingredient in pre-workouts.
Arginine is yet another nitric-oxide booster.
It may not be as effective as citrulline, but has still shown some promise for improving pumps and endurance (3).
Ornithine is an amino acid.
Studies have found it to fatigue-reducing effects (4).
Beta Alanine is a beta-amino acid, which boosts levels of a compound called carnosine.
This can reduce acid and free radical build-up caused by exercise, improving endurance (5).
The effective dose is 2-5g daily.
Creatine is a naturally-occurring acid found in animal food products.
The formula uses a special form of creatine called Magnapower – the verdict is still out on whether Magnapower is any better than the common monohydrate form.
Tyrosine is an amino acid that reduces fatigue and increases performance under stress (8).
500-2000mg is an effective dose.
Caffeine can increase alertness, as well as athletic performance at the higher end of the dose range (9).
Three forms of caffeine are found in Rhino Black Series, which all release at different rates. This intends to provide a smoother, longer-lasting energy boost.
An effective dose is between 200-500mg.
Choline is a brain-boosting compound.
Those whose diets contain higher levels choline tend to have better cognitive performance (10).
Hordenine is a fat-burner and mood-enhancer, which may also amplify the effects of other stimulants (11).
The most common dose is 30-50mg.
Who Takes It?
Athletes wanting a supplement that improves all aspects of their workouts will enjoy Rhino Black Series.
How to Take
Mix between 0.5-1 scoop with 250mL cold water, and consume 30 minutes before working out.
Creatine can cause a temporary gain in water weight, as well as digestive issues if taken in large amounts or without sufficient water.
Caffeine can trigger a rapid heartbeat, and should not be taken in quantities larger than that found in one scoop of Rhino Black Series.
- Massive range of ingredients for improving all aspects of your workout
- Open-label formula with no proprietary blends
- Multiple flavors for everyone to enjoy
- The stimulant dose in a full scoop may be too high for some people
Rhino Black Series is a powerful re-workout formula, which is designed to improve your workouts across the board.
It’s very heavy on nitric oxide-boosting compounds and stimulants, and can almost guarantee a boost in terms of pumps, energy, and endurance.
Although it’s a great all-round pre-workout formula, you may want to steer clear of this formula if you’re sensitive to stimulants.
