Endogenous androgens are responsible for normal growth and development of the male sex organs and for maintenance of secondary sex characteristics. These effects include growth and maturation of the prostate , seminal vesicles , penis , and scrotum ; development of male hair distribution, such as beard , pubic, chest, and axillary hair; laryngeal enlargement, vocal cord thickening, and alterations in body musculature and fat distribution. Drugs in this class also cause retention of nitrogen , sodium, potassium , and phosphorous, and decreased urinary excretion of calcium. Androgens have been reported to increase protein anabolism and decrease protein catabolism . Nitrogen balance is improved only when there is sufficient intake of calories and protein.
Test-P injections are made as a rule every day or every other day. Steroid cycle lasts 6-8 weeks. Testosterone enanthate and cypionate cycles shall be run not less than for 10 weeks. On shorter cycles long esters will not be able to expose their full potential. For enanthate and cypionate is one injection every 5-7 days is enough. However, some athletes prefer more frequent injections in order to provide more even hormone level in blood and to avoid dramatic fluctuations. And don`t forget, that steroid aromatizes very easily to estradiol. Independent on the compound you use, keep your estradiol under control by taking aromatase inhibitors (anastrozole preferably). Antiestrogens (SERMs) are in this context not recommended, because they will reduce the cycle efficiency.
