Antiestrogens and Aromatization

Estrogen is a steroid hormone that stimulates the development of female secondary sex characteristics. One of the most serious side effects of steroids - it is their effect on the production of estrogen by the body (the uncle is becoming a aunt). Despite the fact that estrogen is not used in the sport, they play a key role in the use of anabolic-androgenic steroids. Some steroids, in high enough doses, using the enzyme aromatase can be converted into other hormones (a process called aromatization of steroids). In the case of testosterone-like steroids, these other hormones commonly estrogen. Steroids on dihydrotestosterone basis (the strongest androgen) are not subject to aromatization, as DHT is a metabolite of testosterone (not subjected to further biotransformation). Steroid 17-alkylated structure (oral steroids) generally become weaker estrogens. And some, such as nandrolone (Deca-Durabolin) and trenbolone (Parabolan or Finapliks) converted to progesterone (also a female hormone, estrogen derivative).

Large doses of steroids for a long time, the body stops the natural production of certain hormones (such as testosterone). When the steroid course ceases, the body tries to establish homeostasis by hormonal changes. The average ratio of testosterone to estrogen in a healthy male is 100:1. When the drugs increase the level of testosterone, the body tries to maintain this ratio and increases estrogen. So unless you want to get a full set of side effects after a course of anabolic steroids, including a pair of breasts and extra body fat, do not forget the anti-estrogens. Here are some of them: Nolvadex, Clomid, Proviron, Arimidex.

Also, there are drugs that are not flavored or aromatize weakly. They are known as preparations for drying or burning fat. Their use eliminates the use of anti-side at the end of the course. But they, at the same time, have a weak androgenic and anabolic effects, respectively: Primobolan, Masteron, Winstrol, Anavar, Turinabol (tablets).

Testosterone (male sex hormone) and anabolic steroids (synthetic version of testosterone) are by far the most popular drug among bodybuilders. They are accessible, affordable, extremely effectively stimulate muscle growth and relatively safe (though they may have serious side effects, it is unlikely that any of them can lead to death).

To obtain the desired results, bodybuilders stick to a very large number of different types of anabolic steroids. Often, they use 10-100 times more than the recommended therapeutic dose or a normal physiological levels of testosterone, as well as 2 to 4 different anabolic steroids together. Gifted athletes can gain from 5 to 15 kg of weight and get a very impressive increase in power at a 2-month course with anabolic steroids. Steroids help increase the total volume of blood athlete up to 20%, from which the muscles become more comprehensive. Also, calories burned per day athlete, could double during the course, which allows them to better and easier to get rid of excess fat.

Some common side effects of testosterone and anabolic steroids are: increased blood pressure, increased cholesterol, acne, hair loss, structural changes in the heart, liver and kidneys, and the development of female tissues, sexual dysfunction, infertility, reduced testes, prostate enlargement, aggression and depression increased body hair, and in the most extreme cases - congestive heart failure, heart attack, cancer, liver, prostate and kidney. The most popular and with a strong anabolic effect to date are the following steroids: Testosterone cypionate, Deca-Durabolin, Equipoise, Anadrol, Dianabol, Trenbolone.
