Non stim pre
Honestly this pre workout is the best when it comes to late night workouts because it’s caffeine free but it still feels like normal pre workout and it won’t mess’s up my sleep schedule

Poor customer service and experience
I ordered the non-stim pre workout on accident. I took it once and new something was off. To say the leaset I enquired about exchanging this for the regular stim pre-workout. They said there's nothing we can do. Tgis is why I'd suggest buying from your local Vitamin shoppe or GNC, because they'll let you return/exchange no questions asked. I made a mistake and understand that is was opened, but sometimes to keep a customer coming back you'd think they'd be willing to make the exchange. I belong to one of the largest online coaching and fitness groups, so this has the potential to spread like wild fire.
