Strawberry flavor

The flavor was great!! Mixed well!! The only problem was that it created a weird feeling in my throat. Not sure which ingredient it was that caused it but that is my only complaint

Love, love, love

Love taking Jekyll before a workout. It gives me energy without feeling jittery or upsetting my stomach! Best non-stim pre workout I’ve tried!

Thanks for your review, Mallory! Glad you're loving Jekyll!

llove the non stem for evening workouts

i started using jekell and hyde at the beginning of 23 and i realy like the non stim for after work gym sessions.. but please make more flavors .. im not a big fan of the blue razz and it does not mix well with other flavors..


This isn’t as powerful without the stim but tastes great & adds another level of focus to my workout.

Great Pumps… Questionable Flavor

I purchased a tub of Jekyll through Amazon. I had Mr Hyde Signature in Blue Razz Popsicle, and loved the flavor and effect but wanted to try a stim-free. The pump supplied by Dr Jekyll is fantastic, but the flavor in any amount of water is so acidic that it burns your throat with every sip. I’ve had a couple of occasions that caused me to vomit if i didn’t pace myself while drinking it. Once I got past that part, the pre was great.
