With Mega you get all of the same great pumps and performance of the original, but now you get more focus and an even better level of flavor!*
You asked for the best, and Primeval Labs has delivered with Mega High Stim Preworkout!*
Ingredients
L-Citrulline (6,000mg)
L-Citrulline is a nonessential amino that supports nitric oxide production by increasing plasma levels of L-Arginine, the amino acid that serves as the substrate (“fuel”) for nitric oxide production.*
L-Citrulline offers a high degree of bioavailability than L-Arginine. [3] Furthermore, Citrulline has also been shown to be a better supplement for increasing plasma arginine levels than even L-arginine itself!*
In the end, L-Citrulline is a better option for those looking to boost nitric oxide production.*
With greater NO production comes greater blood flow along with additional oxygen and nutrient delivery to your muscles, supplying them with the necessary nutrients to perform optimally.*
Additional L-Citrulline research indicates it may enhance Vo2 kinetics as well as ATP production, promoting greater endurance and athletic performance as well as lean body mass! [4,5,6,7]*
Beta Alanine (3,200mg)
Beta alanine is a powerful amino acid that helps increase stamina and endurance by increasing muscle concentrations of carnosine. [8,9,10,11,12]*
Carnosine is a powerful intracellular buffer that helps eliminate acidic ions that accumulate during the course of repeated muscle contractions. These acidic ions contribute to the “burning” sensation you feel during training, which induces feelings of fatigue.*
But, this acidic ion build up also inhibits a muscle’s ability to repeatedly contract. Eventually, too many of these ions accumulate, and muscles will no longer contract.*
By increasing intramuscular concentrations of carnosine (via beta alanine supplementation), muscles’ ability to buffer these acidic ions is enhanced, allowing for more work to be completed before fatigue sets in.*
Betaine (2,500mg)
Betaine (trimethylglycine) is a compound that’s found in beets and other plants.*
Over the past few years, betaine has received increased interest among athletes due to the results of several studies (conducted in humans) which note betaine supplementation may boost muscle endurance and increase strength.*
Betaine supports endogenous creatine production, via methylation of the amino acid homocysteine to methionine (a building block of creatine). Additionally, betaine also functions as a powerful osmolyte in skeletal muscle, which encourages muscle cells to absorb extra water, supporting improved hydration and stamina.*
Basically, supplementing with Betaine may help boost power, strength, overall performance, and muscle growth![13,14]*
L-Tyrosine (2,000mg)
L-Taurine (1,000mg)
Choline Bitartrate (1,000mg)
Choline is an essential nutrient that plays a number of roles in the body as a methyl group donor as well as a necessary component for the synthesis of cell membranes. [15,16]*
The vital nutrient is also needed for the construction of an extremely important neurotransmitter called acetylcholine — the “learning” neurotransmitter.*
As the name implies, acetylcholine is heaving involved in learning, and it’s also involved in memory, cognition, and muscular contractions. *
To promote tighter focus and a more robust mind-muscle connections, Mega High Stim Preworkout includes a full 1 gram of choline bitartrate.*
Caffeine Anhydrous (250mg)
Caffeine is the preeminent pre workout stimulant, included to ignite the nervous system, spark motivation, and boost athletic performance.*
Caffeine works primarily by antagonizing adenosine receptors.*
Adenosine is a neurotransmitter that accumulates in extracellular space as ATP (adenosine triphosphate) breaks down. *
When enough adenosine accumulates, adenosine receptors are activated which inhibits the release of several key neurotransmitters, many of which play a role in keeping you alert, attentive, and cognitively “with it.”*
More specifically, the neurotransmitters directly affected by adenosine receptor activation includes [21]:*
Acetylcholine (the “learning neurotransmitter”)
Dopamine (the “reward” molecule)
Noradrenaline
Serotonin (5-HT)
Glutamate (an excitatory neurotransmitter)
Therefore, if you don’t want to feel tired, or want to avoid the onset of fatigue it makes sense you would want to stop adenosine from exerting its effects in the body.*
That’s the beauty of caffeine.*
It is structurally similar to adenosine and competitively inhibits the adenosine receptor, meaning adenosine can’t bind to its receptor.*
This is why when you ingest caffeine, you feel more upbeat, alert, and energetic.*
But caffeine’s benefits extend beyond increased feelings of energy and motivation.*
Research has shown that caffeine supplementation can increase energy expenditure as well as strength, endurance, and anaerobic performance (i.e. resistance training). [17,18,19,20]*
CognatiQ® (100mg)
Theobromine (100mg)
Infinergy™ Dicaffeine Malate (68mg)
Mega High Stim Preworkout catapults you off the starting line with a robust 250mg of fast-acting caffeine anhydrous. Most pre workouts would stop there, but we wanted to deliver the best pre workout energy experience possible, and because of that, we’ve included an additional 68mg of Infinergy dicaffeine malate.*
This slow-releasing form of caffeine provides a sustained release of energy that helps avoid any crash typically experienced with other high-stimulant pre workouts, and ensure you have ample energy to finish your workout and still get work done afterwards.*
Toothed Clubmoss Huperzine A 1% (50mcg)
Huperzine A is a powerful nootropic that complements choline-boosting properties of choline bitartrate.*
How do the two ingredients complement each other?
Choline bitartrate helps directly support acetylcholine production by increasing levels of choline in the body. Huperzine A indirectly enhances acetylcholine levels by inhibiting acetylcholinesterase — the enzyme that breaks down acetylcholine.[39]*
By stacking Huperzine A with a choline donor, Mega High Stim Preworkout helps promote greater acetylcholine levels via two different pathways, fostering more dialed-in focus and a stronger mind-muscle connection.*
