Benefits of StimRush
Greater nutrient delivery
Serious muscle pumps
Increases Nitric Oxide production
Enhanced fat burning
Supports muscle growth
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 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.
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 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.
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 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.
