Caffeine is desirable due to its role as an adrenergic agonist. That is, caffeine stimulates the production of epinephrine (adrenaline) for increased energy, mental focus and delayed time to exhaustion. Caffeine also increases the production of neurotransmitters that promote improved mood and sense of well being
Naturally ocurring L-dopa crosses the blood brain barrier to increase dopamine levels providing heightened sense of well being. >In addition to this beneficial increase in neurotransmitters, Mucuna also acts as a potent antioxidant.
A cousin to caffeine that acts as a bronchodilator which may improve respiratory function during training. In addition to this beneficial increase in neurotransmitters, Mucuna also acts as a potent antioxidant.
Isopropylnorsynephrine is a lypolytic stimulant. That is, it breaks down lipids (fats) and triglycerides into glycerol and free fatty acids. Once these are broken down, the body is capable of using them as energy/fuel, resulting in body fat stores being “burned” to fuel your training.
As an alpha-receptor antagonist, alpha-yohimbine binds to the alpha receptors, “clogging” them and preventing adrenaline and noradrenaline form binding. This allows greater amounts of the fat-releasing chemicals to bind to beta receptors and rev up the fat burning process. In addition, a stimulatory effect is seen on the central nervous system.
