About Steroids

Sustanon 250 is an injection medicine that contains testosterone. Testosterone is the main endogenous hormone, irreplaceable for the growth and normal development of male genitalia and secondary male sexual characteristics. During the life of adult men, testosterone is indispensable for the functioning of the testicles and accompanying structures, as well as for maintaining libido, well-being, erectile potency and for the function of the prostate gland and seminal vesicles.
Treatment of hypogonadal men with Sustanon 250 results in a clinically significant increase in plasma testosterone, dihydrotestosterone, estradiol and androstenedion, as well as decreased levels of SHBG (globulin binding sex hormones). Luteinizing hormone (LT) and follicle stimulating hormone (FSH) levels are restored to normal.
Treatment with the drug Sustanon 250 leads to a reduction in the symptoms of testosterone deficiency. In addition, the mineral density of bones and muscle mass increases, in obese patients, weight loss occurs. During treatment, sexual functions are normalized, including erectile function and libido.
When the drug is used, serum concentrations of HDL (high density lipoprotein), low density lipoprotein (LDL) and triglycerides are low, hemoglobin and hematocrit concentrations are increased, but there is no clinically significant change in liver enzyme level and PSA ( prostate specific antigen). The drug can cause an enlargement of the prostate size without any functional changes observed.
In boys with delayed growth and puberty, androgen use accelerates growth, stimulates the development of secondary sexual characteristics.
Treatment of transgender women with androgens, such as Sustanon 250, promotes masculinization.
pharmacokinetics
Sustanon 250 contains a number of testosterone esters with a different duration of action. These ethers, after entering the circulating blood, are immediately hydrolyzed into the natural testosterone hormone.
A single dose of Sustanon 250 results in an increase in total plasma testosterone, whose Cmax reaches approximately 70 nmol / L and is observed approximately 24-48 hours after administration. In men, testosterone levels return to the lower limit of the norm in about 21 days.
In vitro assays showed a high degree of nonspecific binding to testosterone plasma proteins (more than 97%) and to SHBG.
Testosterone is metabolized to dihydrotestosterone and estriol naturally.
The drug is mainly excreted in the urine as androsterone conjugates.

Interaction with Sustanon 250:
Drugs that induce or inhibit enzymes can consequently reduce or increase testosterone concentration. Therefore, it may be necessary to adjust the dose and / or the interval between injections.
Androgens can increase glucose tolerance and reduce the need for insulin or other hypoglycemic drugs in people with diabetes.
High doses of androgens may increase the action of coumarin-type anticoagulants, which may reduce the doses of these drugs.

    itching, acne
    gynecomastia, oligospermia, low ejaculation volume, priapism, functional disorders of the prostate (hypertrophy).
