Ingredients Label

Active Ingredients

Beta Alanine

Beta Alanine acts as a fatigue toxin buffer, to help you get more reps in your workout (1).

Creatine Hydrochloride

Creatine boosts the ATP activity within your muscle cells to provide more anaerobic endurance, allowing you to have more power and energy (2, 3).

Monohydrate is thought to be a more useful form than hydrochloride.

HMB

HMB is an amino acid that prevents muscle breakdown (4).

It also helps relieve muscle soreness after exercising (5).

Caffeine

Caffeine is a stimulant to provide training energy (6). It is dosed at a rather low 100 mg though.

The effective dose for caffeine is between 200-500 mg per day.

L-Citrulline Malate

L-Citrulline malate is a vasodilator which increases arginine blood levels, thereby increasing blood flow.

This brings more blood to the muscle, increasing the pump effect (7).

Who Takes It?

Dr. Jekyll is taken by bodybuilders who want to maximize their training energy and focus during a workout.

How to Take It

Mix one scoop of Dr. Jekyll with 250 mls of water between 15-30 minutes before your workout.

Do not take any other stimulants while using Dr. Jekyll.

Side Effects

You may have a tingling reaction to the beta alanine, which is dosed at a rather high 2 grams per serve.

The low stimulant dosage should not lead to any stimulant reacted side effects.

Pros:

Lots of flavors
Provides pump effect
Effective recovery effect.

Cons:

Only 100 mg of caffeine.

Conclusion

Dr. Jekyll is a pump and endurance focused pre workout which is low on stimulants.

As a result you won’t get the oomph that comes from higher stimulant products.

You will, however, get more focus, energy and a greater pump.
