Like having tons of energy, strength, stamina and endurance for your workouts? Who doesn't? There's nothing like the right combination of compounds taken pre-workout to deliver consistently mind-blowing workouts to help you achieve your goals. After all, if your workouts suck, you can all but forget about making killer progress anytime soon.
USPLabs Jack3d may promote the desire to lift more weight, pump out more reps and have crazy lasting energy, along with sick muscle-engorging pumps.* The amount of energy and focus is perfect, pumps and vascularity will be out of control, but most importantly you may feel great throughout your entire workout.*
Jack3d Formula Breakdown
Schizadra has been suggested to promote physical force.* In essence, it may be able to provide a stimulating effect to the body and mind.*
Both of these compounds belong to the family of methylxanthine compounds. They are both 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.* Caffeine also has the benefit of fighting fatigue and drowsiness; increasing alertness and improving intellectual efforts along with producing euphoria or a sense of well-being in some cases.*
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. 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.
Furthermore, by increasing carnosine levels, power output may be increased as well.* In short, it may improve power output, while also delaying fatigue; supporting the ability to lift more explosively and for longer periods.*
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.
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.
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.
In short, we can reduce fatigue from occurring by increasing phosphocreatine levels, which in turn will allow for the regeneration of ATP from ADP leading to greatly reduced physical and muscular exhaustion.*
