Natural testosterone in the body is a beautiful thing.  It is produced by the testes upon orders form the pituitary gland, and all is controlled by the endocrine system.  It is delivered consistently to the body and its delivery is regulated based upon need.  When functioning perfectly, it’s a well-oiled machine that does collect some rust as it ages, and there is little issue with prostate health until age 40. Injected testosterone is a whole ‘nother story.  Converted to DHT (dihydrotestosterone) by the body, it immediately sets off a chain of events, which can be hard for the body to overcome.  The pituitary gland orders the testes to halt production of testosterone once it senses the presence of high artificial levels of testosterone or DHT in the body.  The receptors in the prostate react to the DHT by creating growth of ...

Mesterolone is an orally active, 1-methylated DHT. Like Masteron, but then actually delivered in an oral fashion. DHT is the conversion product of testosterone at the 5-alpha-reductase enzyme, the result being a hormone that is 3 to 4 times as androgenic and is structurally incapable of forming estrogen. One would imagine then that mesterolone would be a perfect drug to enhance strength and add small but completely lean gains to the frame. Unfortunately there is a control mechanism for DHT in the human body. When levels get too high, the 3alpha hydroxysteroid dehydrogenase enzyme converts it to a mostly inactive compound known as 3-alpha (5-alpha-androstan-3alpha,17beta-diol), a prohormone if you will. It can equally convert back to DHT by way of the same enzyme when low levels of DHT are detected. But it means that unless one uses ridiculously high amounts, ...
