Steroid hormone molecular structure

Prolactin is a protein hormone that in female mammals initiates and maintains the secretion of milk, the mammary glands having been previously prepared for this function by the action of other hormones. In the female rat, prolactin also maintains the secretion of the hormone progesterone , which is formed by the corpus luteum , an endocrine gland of the ovary . Thus, prolactin is a gonadotropin , its target being an endocrine gland. Moreover, the molecular structures of prolactin and growth hormone are similar, which may explain why they show some overlap in biological properties. In particular, administration of prolactin promotes some growth in many terrestrial vertebrates. Human growth hormone has prolactin-like luteotropic properties.

The Mesterolone hormone is not estrogenic. It does not aromatize and it carries no progestin nature. As a result, the side effects of Proviron will not include any related effects such as gynecomastia or excess water retention. Such adverse effects are impossible with this steroid. This will also greatly reduce the risk of high blood pressure as high blood pressure associated with anabolic steroid use is often due to extreme water retention. In fact, Proviron should provide an anti-estrogenic effect by preventing testosterone to estrogen conversion or at least tremendously slow it down.

The effects of Parabolan do not end with cutting and mass promotion. This steroid will promote enhanced muscular endurance better than most steroids. It will also dramatically improve the individual’s overall rate of recovery. The individual will not tire out as fast and he will recover from hard, intense exercise or activity at an accelerated rate. Due to the powerful androgenic activity, the individual will find this steroid also greatly promotes increases in strength. In fact, some may even notice a slight increase during a cutting phase. Of course, most all will find strength diminishes to a degree when cutting, but more of it will be protected when dieting than would be otherwise. Due to these effects of Parabolan, enhanced endurance, recovery and strength, it can be a fantastic steroid for athletic performance. However, some individuals report decreases in cardiovascular endurance. However, it WILL NOT affect everyone this way. Many will simply enjoy the positive effects of Parabolan.
