ANABOLIC STEROIDS are synthetic (artificial) analogues of the male sex hormone TESTOSTERONE.
What is hidden under this terrible definition of “Anabolic Steroids”? Generally speaking, male sex hormones. Substances that are very natural to the male body. They cause the development of secondary sexual characteristics in men, are responsible for sexuality, contribute to the growth of muscle tissue by increasing protein synthesis in muscles. The latter is called anabolism and that is why drugs that lead to such growth are often called anabolic steroids.
TESTOSTERONE performs many of the most important functions in the body and one of the most important is the formation of male signs, including the growth of muscle mass! The hormone travels in the blood throughout the body and can affect its activity (in our case, it can accelerate the synthesis of new proteins in the muscle cell).
Testosterone is synthesized from cholesterol (cholesterol-androstenedione-testosterone) in the TESTES.
- for MEN = 6-7 milligrams per day
- for WOMEN = 1 milligram per day
In general, there are a lot of different hormones in our body:
- PEPTIDE HORMONES: (amino acid chains) insulin, growth hormone
- AMINO ACID DERIVATIVES: adrenaline, tyrosine
- STEROID HORMONES: testosterone, estrogen, cortisol, progestins
But now we are considering steroid hormones. Or rather, artificial testosterone analogues, which are called ANABOLIC STEROIDS.
There are many of them, because scientists have made different modifications of the original hormone molecule. Some modifications can aromatize (turn into female sex hormones), while some cannot. Some form a more stable bond with the receptor, some less stable. In general, different steroids have slightly different features. But in general, they all enhance protein synthesis in the cell, because they are similar to natural testosterone.
