Great product great pricing

Thanks for your review, Brian! So glad you're loving Jekyll Signature!


Weird after taste good results


Flavor is Blueberry Lemonade, very acidic and had a lot of blue and brown flakes in it that seem to not want to dissolve even when shaken in warm water. Taste is not bad at first but the closer you get to the end it gets worse. When it kicks in it was not bad till like 10min in and the getting warmer was not the problem. It feels like the beginning of a anxiety attack. Honestly would not recommend this stick with the Hyde signature.

Hey Erik, thanks for taking the time to write a review. We apologize Jekyll Signature was not completely up to your standards. At ProSupps we strive to provide the best and highest quality supplements to our customers. With that said, we highly recommend our other stim-free pre-workout, Hyde Max Pump. We're more than happy to send you a tub free of charge, a member of our team will be reaching out to you shortly!

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!
