Beta Alanine

Beta Alanine is responsible for increasing intramuscular carnosine levels, which is a di-peptide that enhances the bodies ability to remove the toxic waste accumulated by lactic acid. In doing so Beta-Alanine has the ability to increase your lactic threshold, meaning you can do more work at a higher intensity for a longer period of time.

Creatine (Monohydrate + HCL)

Both creatine monohydrate and creatine HCL work by increasing intramuscular creatine phosphate levels, however, HCL is characteristically easier to digest and will result in less stomach bloating. By increasing intramuscular creatine phosphate you will have more strength, power and increased muscle size.

Betaine Anhydrous

Betaine is an active metabolite of choline and also acts as an osmoregulator similar to creatine, whereby super-hydrating effects have been shown after ingestion.

Due to its regulatory effects on cellular hydration, betaine has been shown to have an ergogenic effect through sarcoplasmic hypertrophy support and is also responsible for the skin splitting pumps everyone is chasing.


ElevATP is a patented mitochondrial energy intensifier designed to increase the natural production of ATP, which is our primary fuel source used during high-intensity exercise.

N-Acetyl Tyrosine

L-Tyrosine is a natural precursor to the production of the catecholamines adrenaline and noradrenaline, which work both systemically and locally to enhance energy output, maximise nutrient breakdown for substrate availability and improve cognitive function.

With the introduction of an acetyl group, L-Tyrosine becomes more bioavailable and the production of acetylcholine increases, which is a neurotransmitter responsible for improved cognitive function.

Choline Bitartrate

Known as the ‘learning neurotransmitter’ acetylcholine is the biosynthesized by-product of choline in the brain and has been linked to increasing cognitive function when taken orally.

Attaching choline to bitartrate enhances absorbability and when taken acutely prior to a workout, will work synergistically alongside stimulants like caffeine to enhance focus and a feeling of wellbeing.

Caffeine (Anhydrous + Citrate + Malate)

Caffeine is one of the longest standing ergogenic aids with benefits for both the increase in catecholamine release and the simultaneous reduction in the cognitive action of the sedative adenosine.

While all 3 versions of caffeine act on the same receptors for performance enhancement, caffeine malate has been shown to mitigate the stimulatory effect on urination, while caffeine citrate appears to peak faster in the blood stream resulting in a quicker initial hit of energy.


Theacrine is a caffeine-like product that is new to the industry, although shows great promise in stimulating the same excitatory response of adrenaline release, however unlike caffeine, initial research appears to show no desensitisation of the receptors it acts upon meaning you do not have to keep taking more to achieve the same result.
