There is nothing quite like a high-octane training session, so it is no surprise that pre-workout supplements have become so popular. However, those long lists of ingredients in proprietary blends only create the façade of an effective supplement when all you really end up with is enough caffeine to “feel” it and little else. Until Rhino BLACK. MuscleSport International is PROUD to bring you the best that science has to offer, so there are no blends. Only efficaciously-dosed, proven ingredients that have been carefully selected to provide all that is needed from a pre-workout: energy, focus, pumps, and performance. Here are just a few of the rigorously validated ingredients in Rhino BLACK.

6g Citrulline Malate – A dual-threat: Provides huge boosts to training volume and stimulates nitric oxide production. More training volume. Bigger pumps. Maximized gains.
400mg Caffeine Matrix – All the fat-burning, attention-enhancing effects of caffeine without the hard crash or upset stomach!
750mg Nitrosigine – The world’s most effective form of arginine works synergistically with citrulline to maintain improved blood flow up to 3 hours.
750mg L-Tyrosine with 75mg Hordenine – L-Tyrosine is a precursor to adrenaline while Hordenine works to keep adrenaline active within the body.
2g Creatine Magnapower – The single, most effective supplement for increasing muscle mass and strength.

These are just the best of the best. Add on top of that the other half of the proven ingredients and you’ll clearly see just how superior Rhino BLACK is compared to the rest of the field. The best have nothing to hide in something like a mysterious proprietary blend, and there are no secrets in Rhino BLACK – just pure, hard-working ingredients to get your game and your physique to the next level with piercing focus, crushing strength, electrifying energy, flushing muscle pumps, and persevering endurance. Just like nothing can stack up to a high-octane training session, nothing stacks up to the best pre-workout in the game, Rhino BLACK.
