Enhanced fat burning
Supports muscle growth
Boosts endurance
Irresistible flavoring



L-Citrulline (4g)


Citrulline is a non-essential amino acid widely reputed for its ability to boost nitric oxide production in the body via increasing plasma arginine levels.


L-Citrulline has been shown to be superior for boosting nitric oxide compared to L-arginine due to its greater bioavailability. This leads to greater nitric oxide production, and with that come better blood flow, oxygen and nutrient delivery, and massive muscle pumps.


Citrulline also boosts performance by improving ATP production, stamina, and resistance to fatigue.


Betaine Anhydrous (2.5g)


Over the past few years, few supplements have increased in use and popularity like Betaine. A metabolite of choline (an essential nutrient for brain health), betaine jumped on researchers’ radar when it was observed that betaine exhibited many of the same benefits as the king of all bodybuilding supplements -- creatine.


As researchers later discovered, betaine is a valuable methyl donor, methylating homocysteine into methionine, an essential amino acid used for the production of creatine. Betaine supplementation enhances endogenous creatine production, improves strength, power, and lean mass.

Beta Alanine (2g)


Beta alanine is an ingredient that requires little explanation. It’s been around the supplement game for a long time with numerous studies documenting its ability to enhance endurance and improve fatigue resistance.


Once ingested, beta alanine binds to histidine to form carnosine, a powerful intracellular buffer. With greater concentrations of carnosine, your body’s ability to buffer H+ ions increases, allowing you to train for longer periods of time at higher levels of intensity before succumbing to muscle fatigue.

Taurine (1g)

Taurine is a conditionally essential amino acid that functions as an osmolyte, regulating fluid balance and supporting cellular hydration. This powerful little amino acid helps boost endurance, delay fatigue, and improve focus.


Caffeine Anhydrous(350mg)


When it comes to instant energy, few things match the raw stimulating power of caffeine. This age old stimulant delivers a rapid infusion of energy to your central nervous system, sparking you to get to work ASAP.


StimRush delivers 350mg of pure caffeine anhydrous, supplying you with intense energy, unrelenting drive, and the willingness to go ham at the gym.

Hordenine (50mg)


Hordenine is a powerful beta-2 adrenergic agonist naturally occuring in a number of plants including citrus aurantium and barley. As a beta receptor agonist, hordenine triggers the release of stored fatty acids to be oxidized for fuel, thereby preserving glycogen stores.


Hordenine also serves as a noradrenaline reuptake inhibitor, which increases noradrenaline activity supporting greater energy, alertness, and focus.


Theobromine (50mg)


Naturally occuring in chocolate, tea leaves, and kola nut, theobromine is a xanthine molecule closely related to caffeine. Theobromine provides a smooth, long-lasting energy rush to complement the acute, hard-hitting nature of caffeine.


Additionally, theobromine also acts as a vasodilator, widening blood vessels to promote better blood flow. This leads to enhanced nutrient delivery to working muscles supporting better performance, stamina, and muscle pumps.


Cocoabuterol (25mg)


Cocoabuterol is a patented cocoa extract standardized to 50% cocoa alkaloids, supplying natural phenethylamines and methylxanthines to improve energy, mood and focus. The alkaloids also may increase cAMP via beta-adrenoceptor agonism, which support various fat burning and muscle building mechanisms in the body.


Yohimbine HCl (2.5mg)


Completing the intense energy experience of StimRush is the powerful CNS stimulant yohimbine. Used in combination with caffeine and the other powerful beta receptor agonists, yohimbine gives StimRush the kick that really sends its energy surge over the top.


Yohimbine is an Alpha-2-Adrenergic receptor antagonist that stimulates adrenaline (epinephrine) and noradrenaline (norepinephrine) release, igniting the “fight or flight” response, which leads to increased alertness, focus, and energy during training.


This powerful stimulant also enhances fat burning by inhibiting the body’s natural fat storing mechanisms.




To assess tolerance, mix 1 scoop StimRush with 6oz of water 15-20 minutes prior to training. If well tolerated, mix 2 scoops with 12oz of water 15-20 minutes before training. DO NOT exceed 2 scoops per day.

    Good Stuff
    It's a really good pre-workout. I compare it to Primeval Labs Mega Pre,RedCon1 Total War and FitSupremecy Reaper. They all have L-Citrulline 2 -3 g in them,some with the focus factor, which I'm a huge fan of and theres no crash. So I'll be rotating Stim Rush in and out of my top pre-workouts. Fyi I'm 41 and have been working out for 20 years now and have taking a lot of pre's. Very few out there that do the job their suppose to but the ones I listed i rate all 4 stars. Is there a 5 star product out there,doubtful but Stim Rush is closest to it.

    Tastes awesome but delivers no pump!

    My new favorite Pre with Pump!
    First off, those that are thinking it is a bad batch, it's not. It's the GlycerPump that clumps up. Do some research on what the ingredient does. Now, onto the review. I'm big on high stim pre-workouts (Mesomorph, Edge of Insanity, Re1gn, or anything that had DMAA lol), and let me say that this pre-workout hits me just right! The focus and pumps make up for the missing exotic stimulants I'm used to.

    You will get a solid amount of caffeine with 2 scoops (300 and change). I will definitely be buying this when my supply from the BOGO runs out.

    Thanks again A1 and Primeval Labs! <3

    Great product
    I was excited when I finally got my delivery of stimrush. I ordered the strawberry passionfruit and fruit punch flavors. They both taste delicious. Great workouts using the product so far, no crash, no belly aches, no jitters. I had a great amount of energy for 3 hours after the workout. The only minor negative for me would be that the powder was clumpy in the containers when I opened them. It kind of looks and feels like the kinetic sand you buy at michaels. It mixes easily though and like I said before, tastes great. Overall excellent product, highly recommend.

    good but brown sugar
    I love primeval labs and have for some time so I tried this pre for the bogo and of course a1 deleivers like always too notch company received product and both cans came super clumpy. Wasn't sure why till I opened can and it seamed to be damp or have moisture. Has the consistancy of brown sugar like it's packs down in scooper never seen that before. But tried 1 serving to see if it mixed well and it mixed right up product worked well not sure what's up with the clumps maybe bad batch. Anyways good pump good line up.

    Solid, clean feeling preworkout
    I tried this after using mesomorph so it has been a completely different feeling. Although I lived mesomorph, this one is awesome as well. It keeps me dialed in without the gitters. Will buy again

    amazing clean pre workout
    Couldn't pass up the buy 1 get 2 free deal, so glad I tried it. Love the focus and energy it gives me without feeling jittery, will buy it again!
  8. BPS Nutrition Stimrush

    Love this pre-workout. I use 2 scoops with 1 1/2 scoops of Primeval Labs Intracell 7. I have to force myself to leave the gym. I love the sustained energy I get without the crash at the end.
  9. BPS Nutrition Stimrush

    Very good pre workout
    I found this to be a very good pre workout. I recommend to take 2 scoops as 1 scoop is definitely under dosed. 2 scoops will give you 300mg of caffeine and more tingles which I like grin the beta alanine. But if you are not use to handling that much go with 1 scoop. Decent taste. Was a great deal on A1, buy 1 get 2 free for 39.99. Give it a try, you won't be disappointed.
  10. BPS Nutrition Stimrush

    Great Supplement Without any Crashes
    I use two scoops of pre-workout each training session, and the results are apparent. Great supplement that doesn't have any crashing at the end of it. I remain energized and focused throughout my workout.
