The secretion of cortisol is mainly controlled by three inter-communicating regions of the body, the hypothalamus in the brain, the pituitary gland and the adrenal gland . This is called the hypothalamic–pituitary–adrenal axis. When cortisol levels in the blood are low, a group of cells in a region of the brain called the hypothalamus releases corticotrophin-releasing hormone , which causes the pituitary gland to secrete another hormone, adrenocorticotropic hormone , into the bloodstream. High levels of adrenocorticotropic hormone are detected in the adrenal glands and stimulate the secretion of cortisol, causing blood levels of cortisol to rise. As the cortisol levels rise, they start to block the release of corticotrophin-releasing hormone from the hypothalamus and adrenocorticotropic hormone from the pituitary. As a result the adrenocorticotropic hormone levels start to drop, which then leads to a drop in cortisol levels. This is called a negative feedback loop.
Trenbolone is without a doubt one of the most beneficial anabolic steroids on the market. When we consider the therapeutic benefits of Nandrolone, or even Testosterone, it may not quite match up but on the basis of raw power and physique transformation Trenbolone Acetate is the king. No steroid will be as beneficial when cutting, not even close, and when bulking it is nothing short of fantastic. While Tren is beneficial during cutting and bulking phases, if you’re only going to use it in one phase always choose cutting. Many will actually need to limit their Trenbolone Acetate use to one phase due to the harshness of the compound in some men, especially when we consider cardiovascular strain. However, solid responders who are in excellent health should find they can use the steroid during both phases with a high level of success.
