Designed for ultimate versatility, Dr. Jekyll® Signature will power you through the toughest of workouts without the use of traditional stimulants such as caffeine or TeaCrine that were in the previous version. Dr. Jekyll® Signature now features a unique cognitive drive matrix and adaptogenic matrix to promote focus and sustained training intensity. Rest assured, Dr. Jekyll® Signature is even more effective than its predecessor even without caffeine. With the addition of nooLVL™ and the impressive panel of powerful nootropics, the new Dr Jekyll Signature will take your energy, pumps and focus to an unparalleled level.†

Both Mr. Hyde® Signature and Dr. Jekyll® Signature were designed for the ultimate in pre-workout experience with both designed to maximize training capacity and performance. The difference is that Mr. Hyde® Signature was designed with an emphasis for those looking to achieve extreme energy and focus and features a powerful stimulant blend. Dr. Jekyll® Signature on the other hand was designed with a stimulant-free approach with emphasis on maximizing pumps and training output with a cognitive drive matrix for increasing training intensity and focus without the use of stimulants. Both feature the power of Nitrosigine® for increased and sustained blood flow, with Dr Jekyll® Signature adding an even more powerful focal agent in nooLVL™.

Absolutely! Mr. Hyde® Signature and Dr. Jekyll® Signature were designed to perform individually and work as a stack! By combining both, you harness the power of extreme energy and focus with enhanced pumps and training capacity. We recommend assessing your tolerance if you decide to stack the two products by starting with ½ a scoop of each before proceeding to a full serving. †

SUGGESTED USE: Mix 1 scoop of Dr. Jekyll Stimulant-Free 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, 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.

James Pitts
Jekyll and Hyde

Combining signature Jekyll and Hyde preworkout is my favorite pre workout combination. The pump and mental focus from Jekyll with the energy surge from Hyde gives me my best days in the gym.

Thank you so much for your review, James! Keep up the great work!

Joshua Fraser

Great for non-stim wanted workouts. I use this for light back days and leg days. Great stamina and a great sweat.

Hey Joshua! We appreciate your review, so glad you're enjoying Dr. Jekyll Signature!

Jeff K
Best non stim pre out there

This stuff has great energy matrix and will make you sweat. If you don't want the high caffeine pre workout I recommend trying this. The lemonade flavor is best. Not a fan of the lollipop punch.

Hey Jeff! Thank you for your review, happy to hear you're enjoying Dr. Jekyll!
