What is in USP Labs Jack3d?
Geranium (1,3-Dimethylamylamine or Methylhexamine)
This plant contains a powerful compound. It produces sympathomimetic effects in the body, resulting in strong Central Nervous System (CNS) stimulation, allowing for improved strength output, focus, alertness and mood. Side benefits may include fat loss due to potential appetite suppression, as well as through increased work capacity and the possibility of increased norepinephrine release.
Schizandrol A
Schizadra increases physical force. In essence, it is able to provide a stimulating effect to the body and mind.
Methylxanthines (Caffeine & Theophylline)
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; enhancing the flow of thoughts; increasing alertness and improving intellectual efforts along with producing euphoria or a sense of well-being in some cases. Just as these methylxanthines can increase the effectiveness of compounds, it is thought that it may do the same for the unique compound found in Geranium.
Beta-Alanine
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 can be increased as well. In short, you are able to improve your power output, while also delaying fatigue; you can lift more explosively and for longer periods.
Creatine Monohydrate
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 prevent or reduce fatigue from occurring by increasing phosphocreatine levels, which in turn will allow for the regeneration of ATP from ADP leading to greatly reducing physical and muscular exhaustion.

Although I was skeptical at first, once I had found my tolerance to this product I can really say it does increase your focus and overall energy. The white raspberry flavour is also very nice! 10/10

Great NO supplement, i would definately recommend this one along with Animal Nitro. Only downside is the 250grams package will only last you for 15 training sessions (16grams each time).
