What is post-cycle therapy?
Post cycle therapy is a tried and true method of helping to solidify your gains by raising natural testosterone levels and lowering estrogen levels once your cycle is over. When you add external hormones to your body, your own natural production becomes suppressed. Your body attempts to compensate your endocrine system by stabilizing the other hormones, which results in an increase in estrogen. Once you quit supplying your body with external hormones, your natural testosterone will be low and estrogen will be high. Therefore, anti-estrogens are taken to halt the manufacture of estrogen in the body. This will result in higher testosterone levels, hence making it easier to keep your gains. Post cycle therapy should begin the next day after the prohormones have stopped being taken. Common post cycle therapy drugs are listed below with dosages: 6OXO 6oxo is an aromatize inhibitor sold by Ergopharm. It is the best over the counter anti-estrogen available for post cycle use.

Natural production of testosterone is controlled by the Hypothalamic-Pituitary-Testicular Axis (HPTA). When the body senses the need for testosterone, the HPTA releases GnRH (Gonadotropin-Releasing Hormone), which signals the release of LH (Luteinizing Hormone), which in turn signals the production of testosterone. The increased testosterone then signals back to the HPTA that testosterone needs are met. This provides a negative feedback system that keeps natural testosterone levels within a certain range. However, when an exogenous steroid/prohormone is administered, it will also signal the HPTA that testosterone needs are met. The HPTA then stops signalling the production of testosterone, and this is what leads to the shutdown of natural production of testosterone during a steroid cycle.

This is the reason that testicular shrinkage is experienced by many who use steroids/prohormones, especially for longer cycles.
