Jack3d Never have a bad workout again!!
By addressing both the regeneration of ATP, while also limiting Hydrogen ion accumulation, we are able to provide a one-two combination that effectively reduces fatigue to an amazing degree.
In short, we can prevent or reduce fatigue from occurring by increasing phosphocreatine levels, which in turn will allow for the regeneration of ATP from ADP.
By supplementing with creatine, we are able to increase the levels of phosphocreatine in muscle. Phosphocreatine is a high energy buffering compound which is able to donate a phosphate group to ADP, allowing the formation of ATP once again.
Consequently, muscle fatigue is also related to energy loss in skeletal muscle, specifically, ATP being converted to adenosine diphosphate (ADP). In effect, one phosphate group is lost and must be replenished in order for the muscle cell to continue on working.
It is no coincidence that the most explosive athletes (e.g. sprinters) in the world have higher carnosine levels in their muscles. Looking to the animals of our world provides us with yet another example; the most explosive animals such as greyhounds and thoroughbred horses also have the highest level of carnosine in their muscle tissue as well.
It is so important because it acts as a buffer of sorts, preventing the increase of acidity or Hydrogen ion accumulation in skeletal muscle; something which is thought to contribute to the fatiguing of muscles.
Carnosine is an extremely important dipeptide that is generally present in rather high concentrations in skeletal muscle, though it is also found in nervous tissue and other excitable tissues as well [12,13].
Beta-alanine serves as the rate-limiting precursor of carnosine and as such, it has been shown that by supplementing with beta-alanine, you can greatly increase carnosine levels in skeletal muscle tissue.
This is one area where USPlabs Jack3d truly separates itself. It's not just a ton of caffeine thrown in so you can "feel it."
Jack3d's ingredients are perfectly blended for an awesome synergistic effect...
...Most formulas just throw in a ton of caffeine and hope for the best.
Caffeine has the benefit of fighting fatigue and drowsiness; enhancing the flow of thoughts; increasing alertness and improving intellectual efforts along with producing euphoria or a sense of well-being in some cases.
In terms of specifics, at the cortical level, caffeine is also thought to promote increased wakefulness or vigilance, via adenosine receptor antagonism, causing stimulation of cholinergic neurons in the basal forebrain and reinforcing inhibition exerted upon sleep-promoting GABA neurons. The stimulant effects are exerted directly upon the cerebral cortex, medulla oblongata, and spinal cord.
Caffeine belongs to the family of methylxanthine compounds. It's able to stimulate the CNS, while also stimulating contractility of skeletal muscle directly and this may partially be due to the release of catecholamines such as norepinephrine.
And, as we all know, cortisol can be dramatically increased during a workout and can stop muscle growth in its tracks.
Last, but certainly not least; unlike various stimulants which can increase catabolic hormone levels (i.e. glucocorticoids), this compound has been shown to lower levels of hormones like cortisol in animal models.
Has been shown to greatly increase the capacity of muscles to perform work, while also increasing physical force. In essence, it is able to provide a stimulating effect to the body and mind.
This compound is an exciting one...
Put Simply - Jack3d is one of the most ground breaking supplements to hit the Industry in years!
While we may negate the increase in Hydrogen ion levels in skeletal muscle by increasing carnosine levels, we still must overcome one more obstacle in order to allow us to prevent fatigue while working out. In this case, we must use a compound which can ultimately increase the adenosine triphosphate (ATP) levels in muscle. ATP, as we all know, is a high energy nucleotide which acts as the major energy carrying molecule in our bodies.
