In my opinion, the physiology of the stack is as impressive as the stack itself!
For example, the effect of positive aggression Jacob has noted could be due to any one of the products he has mentioned. PowerFULL, for example, promotes vast increases in brain-tissue Dopamine levels, which is the body’s most potent and direct regulator of Prolactin; PRL, in turn, mitigates Testosterone levels through negative feedback. By binding to D2Rs [dopamine-2 receptors] on the lactotrope cells of the Pituitary, the cells responsible for PRL-production, Dopamine can significantly and transiently increases levels of Total T. This has been displayed both with synthetic L-DOPA, and recently, by Mucuna itself. Such a transient and immediate increase in Total T would most definitely produce the so-called “he man” effect Jacob noticed, characterized by increased levels of confidence, and positive aggression.
This positive aggression could then very well have been supplemented by the action of the beta-2-adrenergic agonists found in Jack3d, which are known CNS-stimulants and promoters of nutrient metabolization [epinephrine is one of the body’s primary metabolizing hormones] and increasers of aerobic capacity. The increased oxidation of both fatty acids and carbohydrates would have provided a substantial ‘real-energy’ boost to coincide with the AMPk-mediated actions of Anabolic Pump, further leading to Jacob wondering “where the lactic acid went?” This in itself is not considering the vasodilation noted from the sapogenins found in the Chlorophytum component of PowerFULL, and/or those found in PRIME.
In all, it seems Jacob stumbled upon the “perfect storm” of aggression, nutrient metabolization, CNS-stimuation, lactic-acid buffering and ATP-consumption increases!
