Mr. Hyde is a pre-workout supplement by Pro Supps.
It’s designed to improve workouts by increasing focus, pumps, and performance.
Pro Supps is an American supplement company which was founded in 2004.
Creatine is an organic acid that occurs naturally in food like meat and eggs.
Creatine Nitrate is a less-commonly used form of creatine, but appears to match the results of others.
The Nitrate component may also increase Nitric Oxide levels, which could improve endurance (3).
An effective dose of Creatine is 3-5g daily.
Beta Alanine is a beta-amino acid that boosts Carnosine levels in skeletal muscle. This prevents muscle fatigue by reducing the acid and free radical build-up from exercise (4).
The effective daily dose is 2-5g.
L-Citrulline is an amino acid that increases endurance and reduces soreness (5).
The body converts it to Nitric Oxide, which dilates blood vessels and increases blood flow. This gives a better “pump” effect.
The optimal dose is 6-8g.
Agmatine is a compound that shows promise for improving pumps, mood, and brain health. It also reduces pain and might promote recovery, but more research is needed in humans.
Caffeine can greatly increase power output and alertness (6).
Mr Hyde also includes two extra forms of Caffeine; Dicaffeine malate, which is slower-releasing and easier on the digestive system, and Caffeine Citrate, which is absorbed more rapidly.
An effective Caffeine dose is about 200-500mg.
GABA (Gamma-Aminobutryic Acid)
GABA is an amino acid shown to improve mood and focus, through a calming effect.
Choline is a molecule that is used by the body to make Acetylcholine, a neurotransmitter.
Studies have shown that individuals who consume more Choline demostrate better cognitive performance (7).
Who Takes It?
This product is geared towards those with a high stimulant-tolerance, and are seeking to improve the intensity and duration of their workouts.
How to Take
Mix one scoop with 250mL of cold water, 15 to 30 minutes before exercise.
Do not consume Mr. Hyde within 4 hours prior to bedtime.
Do not take other products that contain caffeine or any other stimulants while using this product.
The large dose of Caffeine may cause an upset stomach if taken without sufficient water, or if taken on an empty stomach.
You may feel a tingling sensation throughout your body from Beta Alanine.
- Super high-caffeine dose makes it perfect for those who have a high tolerance for stimulants
- Effective ingredients have been used for both pumps and performance effects
- Pro Supps have included a huge range of flavours, so you’ll never get bored of the taste
- A smaller than optimal amount of Creatine is used
- The mood and focus ingredients are not so well-proven, and there are other alternatives that could have been used
Pro Supps has a super high-stimulant formula in Mr. Hyde, and provides a variety of other ingredients that will add to your performance in the gym.
It could, however, do with a greater dose of Creatine and pump ingredients.
