Testosterone is the main male anabolic and androgenic hormone and is responsible for many different biochemical reactions in the body. The active substance of the vast majority of all anabolic steroids is a molecule of "pure" testosterone, or it, but with various changes in the chemical structure. Testosterone steroids are considered the most natural and safe for the human body. All testosterone preparations can be divided into "short" and "long". Separately, a suspension (aqueous solution) of testosterone should be distinguished, which is currently produced by only a small circle of manufacturers. Among them, the most famous is the Aquatest trademark. It is also extremely rare to find on sale the tablet form "undecanoate". Testosterone esters are testosterone preparations based on oil solutions for injection. The most used anabolic drugs in bodybuilding and in general sports and medical practice. Depending on the length of the ester chain "attached" to the testosterone molecule, it is determined how prolonged the action of the drug is, and how often its injections will be needed.
Types of testosterone esters
"Propionate" and "Phenylpropionate" - have a short and medium ether chain, respectively, which causes their half-life of 2 days for propionate and up to 4 days for phenylpropionate. Suitable for drying and building muscles."Enanthate" and "Cypionate" are long ethers with half-lives up to 7-10 days. Great for building muscle
Composite forms are combined steroids based on several forms of testosterone with different release rates. They combine the features of "short" and long "broadcasts" at the same time.
Properties and main effects of testosterone
- Acceleration of protein synthesis in muscle cells allows you to intensify muscle growth (even in solo) and recovery after physical exertion;
- Responsible for the development of sexual characteristics and spermatogenesis;
- Increases sexual performance;
- Enhances appetite, general endurance, strength indicators;
- Activates the burning of adipose tissue;
- Improves the condition of the ligaments and joints by increasing the production of synovial fluid;
- Improves the emotional state and readiness for training, as well as the quality of life in general;
- Protects against overtraining and heart disease;
- Compatible with almost all AACs.
Testosterone: dosages and approaches for use in bodybuilding
This is one of the few steroid drugs that, even in "solo", provide a powerful increase in muscle mass and other properties described above. As a rule, testosterone is injected into the body through intramuscular injections, and the course duration is often 6-8 full weeks. The dosage range and frequency of administration depend directly on the ester used. So, suspension, (Aquatest) and propionate are injected at 50-100 milligrams daily or every other day. Phenylpropionate 200 mg every 4 days, and enanthate and cypionate - once a week, 250-500 milligrams. For too long cycles of more than 6-8 weeks, additional injections of chorionic gonadotropin are a prerequisite for continuing. Unfortunately, for all testosterones, conversion to estrogen is inherent, which is why there is a need for the prevention of related complications, the main of which may be gynecomastia. For these tasks, aromatase inhibitors are used: Excedrol, Letrozole or traditional Anastrozole. The latter is used at a dosage of 0.25-0.5 mg every 3 days from the 1-2 week of the course until its completion. In the case of prolonged esters of enanthate, cypionate - also another 2 weeks after the final injection (until the steroid is completely removed from the body).
Post cycle therapy
Post-cycle therapy is carried out using Tamoxifen or Clomid. In the case of using propionate, phenylpropionate and testosterone suspension, it starts on average 3 days after the completion of the course. If the course was carried out on the basis of "long" cypionate and enanthate - 10-14 days after completion, and in both cases lasts 3-4 weeks. Tamoxifen is used at 30-20-20-10 mg daily for 1-2-3-4 weeks, respectively. Clomid - 100-50-25-25 mg per day at 1-2-3-4 weeks of PCT. If testosterones have been used in conjunction with Deca, Oxymetalone or Trenbolone, only Clomid can be used for PCT.
