Everyday the mythical phoenix rose like the sun – just like Stammpede’s namesake Steve Stamm. He never missed a day of work in over 30 years as a mechanic. He embodied the connection of mind and body, utility and guts. Our Stim-Free Stammpede is a nod to Steve’s spirit to bring it all together, focus on the task at hand and get it DONE!

Stim-Free Stammpede is the workout companion for those who are sensitive to the caffeine and beta-alanine found in stimulant-based preworkouts. Our stim-free formula utilizes Lion's Mane Mushroom to improve mood & boost focus, and Taurine to support energy metabolism and boost physical performance.

  • Stim-free stammpede sour cherry is a great product! It has a decent flavor & definitely gives you that extra oomph you want during your workout. I drink it before heading out on a longer run when I’m building up mileage to train for an upcoming distance run.

  • All pump, no jitters. Pretty good. I get a good pump and no jitters. Normal stim pre-workout would ruin my sleep ( I workout after 5 pm). This tastes good, gets the job done and no jitters

    — Ryan P. Customer Review
  • Love this stuff! Pushes me through my workouts and I am able to fall asleep after working out in the evening. Def a staple in my routine.

    — Casey C. Customer Review
  • This has become a part of my everyday routine, even the days I don’t lift. I really think it supports me, physically and mentally through the day. So glad I found something I love, without caffeine, that can sit right on my counter (P.S. your product packaging rocks!!) that I enjoy using daily!! I also love that you always text me before my subscriptions ship, making them super easy to manage :)

Great taste, perfect to avoid being over caffeinated for my afternoons workouts

Best non-stim pre-workout I’ve tried!

I definitely notice a difference with this pre-workout and have better energy and focus for my evening workouts. Other stim free pre-workouts have either made me feel strange or had no effect. I will continue to purchase this for sure.

Excellent product

This is a great vegan product. Have worked out with and without taking this product beforehand and I can definitely tell a difference in energy level and stamina. I would definitely recommend this product to anyone looking for an extra boost for their workouts.

All Pump, No Jitters

Great pump minus the jitters. I like to alternate between this one and the regular stammpede depending on the time of the day Inam working out. A lil less potent than the regular, but effective.

Great taste

I personally love this! I think the taste is great and mixes well! It doesn’t give you that tingly/jitter feeling at all, which I am glad it doesn’t! I also love that I can have a scoop of this mid day just to get through the long parenting days. It’s multipurpose!!

First time trying! Make sure you mix more than other products, otherwise there’s some sediment at the bottom! Great alternative to stim products.

I'd never used a pre-workout before and was wary of most because I don't do much caffeine. This product is AMAZING! Tastes great too!
