Stammpede Bullberry Preworkout

12 reviews

Bo Jackson, Jackie Joyner-Kersee and Steve Stamm. All the greats could do it all, and bring it hard. Whether he was coaching little league, growing taters or fixing the Dodge, Steve was our local hero. The Dodge may have been a ram, but Steve was never afraid to grab the bull by the horns - get your Bullberry and Stammpede through your workout!

**Individual Results Vary**

    1. As you warm up, you will notice the brain/body connection produced by the tyrosine and the taurine
    2. As you work through your warm up, you will feel a distinct connection to your muscles, that’s the betaine and citrulline malate acting.
    3. As you begin your training session, there will be an itchy/tingly feeling along with a great sense of motivation. That is the synergistic effect of beta-alanine (tingly feels) with caffeine (sense of motivation)!
    1. First Day: Test the water with half a scoop
    2. Libertarians: One scoop will impassion you
    3. Anarchists: Two scoops for bedlam (Turbo Mode)
    4. Take 1-3 scoops of Stammpede about 20 minutes before beginning the active portion of your workout.
    5. The number of scoops depends on your mission.
    1. DO NOT USE if you are pregnant or nursing, prone to dehydration, or will be exposed to excessive heat. Discontinue use immediately and call a physician if you experience chest pain, tremors, dizziness, severe headaches, nausea, irregular heartbeat or shortness of breath. Consume a minimum of 120 ounces of water daily in conjunction with a healthy diet and regular exercise. KEEP OUT OF REACH OF CHILDREN AND PETS. Too much caffeine can cause nervousness, irritability, sleeplessness and rapid heart beat.

New Favorite

Really enjoy this pre workout. I'm sensitive to stimulants in general and struggle to find a pre workout that is more 'slow burn'. Initial ramp up and tingles isn't overwhelming and energy sustains through most of my workout, a traditional weightlifting 90-120minutes. My favorite part is it dissolves so fast and thoroughly in water, no shaker required. Highly recommend

It just works

Been using for about a month now and can say I am enjoying this product. Really helps me get into the mindset to workout after a long day at my job and helps me all the way through it. Especially for someone like me that has a higher tolerance for caffeine and other stimulants i was really surprised how much I felt it.

Stammpede is awesome

I have ordered grassfed whey and watermelon, my favorite stammpede flavor ( please come back). My experience with bullberry stammpede is pretty amazing! I like the taste and love the clean sustained energy when using it. Would definitely recommend it to anyone looking for great, clean supplements.

Best one so far!

I've been using EFM products for what seems like forever and they literally keep getting better. I love this pre-workout and I thought I couldn't love one more than the lemonade! This is a punch to the face but does not have that chemical gross after taste at all. My performance is always strong and consistent when using this product - at no point do I hit a wall and crash with this. It is awesome! Missing out if you don't try this product.

Bull berry Preworkout

Product works great. Not the greatest tasting preworkout on the market but better than some. Leaves me feeling clean and not sick or worried about artificially added ingredient. Would buy over other preworkouts.
