STIM offers a potent, no-nonsense energy boost when needed. It's crafted from a unique ingredient combo that delivers an exhilarating experience.

Its key aim is to provide steady, potent energy, ideal for intense workouts or demanding workdays.

STIM's core trio: Caffeine, TeaCrine®, and Dynamine™.

  • Caffeine Anhydrous (200mg): A concentrated caffeine powder from coffee plants.
  • TeaCrine® (200mg): Offers energy, mental clarity, and mood enhancement, synergizing with caffeine for longer-lasting effects without jitters.
  • Dynamine™ (200mg): Enhances energy, mood, and focus by influencing neurotransmitters and extending caffeine's effects.

A major study confirmed Dynamine™'s ability to prolong caffeine's impact and effectiveness when combined with TeaCrine®.

Barr's TIPS

This is the perfect stim that will have you feeling like a god without the jitters or the crash. It went through a couple of iterations during testing but one thing clearly stood out - the combo of Caffeine + Teacrine® + Dynamine™ is absolutely f##king nuts!

Originally it included some more of your typical pre-workout staples but the more I started to take it, the more I thought it had more applications than just as a pre-workout supplement. The energy feels so clean - half mental alertness, half physical sharpness. During flavor testing I actually started replacing my morning coffee with a scoop and the energy lasted long into the afternoon with no crash and a really nice mood and mental boost.

Combining this with the PUMP Pre-Workout gives you the clarity, tunnel vision feeling and insane mind-muscle connection to go along with the skin-splitting pumps, strength and endurance.

Jared Bost
Stim Preworkout

I’m usually cautious when picking stimulant pre workouts and bought this one spontaneously. First off, them being third party tested is huge and marks a significant standing in the supplement industry. Second, and arguably the most important, I didn’t have any over stimulus or anxiety. Some pre-workouts can make me feel sick and this did no such thing. It did what it was intended to do and get me through a workout.

Not a fan

So I figured I would give this several tries before writing a review and I gotta say.....I'm not really a fan. I know people are different, but this hasn't done anything for me. I don't feel the focus or the caffeine. Maybe if you put this is something else. As far as the taste, I think the flavor is good, but for me it's grittier than other brands I have had. With that, I'll stick to buying the Greens because they are awesome, but I'll be passing on this.

Thank you for the feedback, this was our very first product, and we plan on keeping it in the line up and reformulating it!!

Best Pre-Workout On The Market!

Good Sh*+

After taking for the first time I experienced a level of focus I hadn’t felt in a long time from a pre workout. The balance was perfect in all aspects, many of which I didn’t seem to know were effecting me from the lack there of. Highly recommend to any newbies or veterans of the weightlifting sport.


This pre workout was by far the cleanest I’ve tried on the market. I felt very focused and on a nice steady pace throughout my entire workout with any crash. I highly recommend if you workout during the evening and have to sleep after, this product will not keep you up all night, it simply does the job and makes you feel great while training.
