Product Information

DR. JEKYLL® SIGNATURE

Dr. Jekyll® Signature is the ultimate stim-free, pump-inducing pre-workout. This formula combines an unrivaled nitric oxide response blend known as the Performance Matrix, with a Cognitive Drive Matrix for focus and training intensity. In addition, Dr. Jekyll® Signature includes an Adaptogenic Matrix featuring Ashwagandha and thermogenic ingredients to help lower cortisol levels and increase metabolic rate, completely stim-free.

WHO IS IT FOR?

Dr. Jekyll® Signature is designed to push you through the toughest training sessions, without any stimulants. Perfect for those who train at night, or simply not a fan of caffeine.

WHY IS IT BETTER?

Dr. Jekyll® Signature is the only all-in-one stimulant-free pre-workout that addresses all key functions that support improved performance-cognitive function, strength, improved endurance, blood flow, thermogenesis and adaptogenesis.

HOW TO USE IT:

Mix 1 scoop of Dr. Jekyll® Signature with 8oz of cold water. Consume 15 to 30 minutes before exercise. If you decide to stack with another pre-workout, such as Mr. HYDE® Signature, assess your tolerance with 1/2 scoop of each before proceeding to a full serving. Shake container well before use. Some users may experience a warming sensation and increased sweating after use. This is attributed to Aframomum melegueta.

Sometimes I get a peppery taste and it must be some combination of what is in the supplement. So far no issues. The strawberry is a bit sweet for my liking.*

Great Stim-free pre-workout. Both Jekyll and Hyde are good pre-workout choices, just depends if you want the caffeine or not.*

The orange is better than the blueberry lemonade, which has a lot of burn to it. Good pre workout.*

For a caffeine-free pre, I guess it does the trick but just didn't give me enough pep that I'm looking for in a pre-workout. Guessing I could stack with something else but I traditionally look for an all-in-one pre.*
