The minus of bulking preparations that you received by mail is that you can not be sure what there is in fact. But, fortunately, there are several ways to personally test them for quality, this is a translation of an article from a forum that will be a good source of information for you.

“Obviously, the best test is the laboratory test, but you can not bring steroid powders every time, it’s expensive, and even stupid, and you can also look at the description in the chemistry books (Merck index) to understand what is in the shit, and what But this is only an approximate description.

Anabolic steroids are pharmacological preparations that copy the effect of the male sex hormone testosterone and dihydrotestosterone. Anabolic steroids accelerate the synthesis of protein within cells, which leads to severe hypertrophy of muscle tissue (in general, this process is called anabolism), resulting in widespread use in bodybuilding. The action of anabolic steroids is conventionally divided into two directions: anabolic activity and androgenic activity. The word “anabolic” comes from the Greek “anabolein”, which translates as “build up”, the word “androgenic” comes from the words “andros” and “genein”, which translates as “making a man” or “making sense”.

The mechanism of action of bulking steroids

The mechanism of action of anabolic steroids is not similar to the action of peptide hormones. Once in the blood, the molecules of steroids are carried throughout the body, where they react with skeletal muscle cells, sebaceous glands, hair pouches, certain brain zones and some endocrine glands. Anabolic steroids are soluble in fats, so they can penetrate the cell membrane consisting of fats, within the cell anabolic steroids interact (bind) to androgen receptors of the nucleus and cytoplasm. Activated androgen receptors transmit a signal to the interior of the cell nucleus, resulting in a change in gene expression or activation of processes that send signals to other parts of the cell. As a result, the synthesis of all kinds of nucleic acids is stimulated and the process of formation of new protein molecules starts.

The effect of anabolic steroids on the growth of muscle mass is due to the following mechanisms:

  • protein synthesis is accelerated
  • Reduces recovery time
  • decreases the effect of catabolic hormones (cortisol, etc.)
  • shift the differentiation of cells toward the muscle, reducing the formation of fat
  • acceleration of metabolic reactions, due to which the decomposition of fat occurs
