Prolactin inhibitors are drugs that reduce the amount of prolactin in the body. The use of this type of drug is very important during the programs based on anabolic steroids, which have progestogenic activity, for example, such as nandrolone or trenbolone.
During the use of the above anabolic steroids, their molecules are attaching to progestin receptors in the body, thereby triggering a number of processes that block the action of dopamine. Dopamine – a hormone that is responsible for the production of prolactin in the body. In this regard, the level of prolactin increases, which in turn can provoke such unpleasant effects as:
- fluid retention and accumulation of adipose tissue in the body;
- significant deterioration of the hypothalamus-pituitary-testicular arc;
- depression libido;
- deterioration of sperm quality;
- atrophy of testicles, etc.

It plays a significant role in the formation and functioning of the immune system, takes part in the formation of sperm, as well as in water-salt metabolism. That is why you should always ensure that its level was within the norm (not lower/not higher).
