Many studies have shown that there is something that can be done in order for you to keep producing natural testosterone on cycle and that my friends is simply by suppressing Prolactin.
Prolactin is a hormone that when increased in the human body will decrease the normal levels of sex hormones, estrogen in women and testosterone in men.
As mentioned before some studies have confirmed the suppression of prolactin will lead to you tricking your HPTA (hypothalamic pituitary testicular axis) into believing that it is not on cycle. When prolactin was reduced in the body, the HPTA was able to remain unaffected by testosterone treatments. The results can reflect that the mid-range levels of prolactin reduce the sensitivity of the HPTA system.
It was also highlighted in studies that having higher prolactin levels while on cycle will result in an increased HPTA (hypothalamic pituitary testicular axis) responsiveness, meaning a fast shutdown of the HPTA. With high levels of prolactin in the system it will lead to sensitize the HPTA negatively in regards to gonadal steroids.
As you can see this is all starting to make perfect sense, as Trenbolone, Deca Durabolin (nandrolone deconate) are easily the most suppressive of the anabolic steroid family. And the thing that makes these steroids so suppressive is there ability to bind to the progesterone receptor, significantly increasing prolactin. This is the main reason the HPTA (hypothalamic pituitary testicular axis) shuts down and halts the production of natural testosterone in the body. For example a single injection of 100mg of Deca Durabolin caused a total 100% reduction of natural testosterone production, and it took a full month before the return of natural testosterone in the body levels out.
With my experiences in taking CABERGOLINE (Dostinex) (suppressor of prolactin) I can happily confirm that this product is the REAL DEAL. Cabergoline drove my libido through the roof and I felt like my sex drive was that of a 18 year old. I also noticed that I was experiencing very powerful orgasms and my recovery time between sex was much faster I felt locked and loaded at all times! Having experienced Deca Durabolin and testosterone before it is easy for me to say that Cabergoline (Dostinex) is a must have when you are cycling trust me when I tell you this, it will change your cycle experience for the better!
