Legal Anabolic Steroids Testosterone propionate CAS 57-85-2 White Powder for Mass Gaining
Chemical name: Testosterone propionate
Purity : 98.25%
CAS Registry Number: 57-85-2
Einecs No: 200-351-1
Grade : Pharmaceutical Grade
Storage: Shading, confined preservation
Drug Class: Injectable Anabolic Androgenic Steroid
Usage : Testosterone propionate can be used as pharmaceutical material. It acts much faster than other testosterone esters such as cypionate or enanthate, and requires a much more frequent dosing schedule, in order to maintain stable blood levels. The main function of Testosterone propionate is to promote metabolism. Anabolic effects include growth of muscle mass and strength, enhancement of bone density and strength, and stimulation of linear growth and bone maturation.
Testosterone Propionate is a single ester testosterone compound and represents one of the most important testosterone compounds every manufactured. When synthetic testosterone was first created it was in its pure form. Simply put there was no ester attached, thereby providing a fast acting compound that would necessarily require a very frequent administration schedule. In 1937 the pharmaceutical giant Schering out of Germany would release the first ester base testosterone in Testosterone Propionate under the trade name Testoviron. The same trade name it would eventually give to its Testosterone Enanthate product. By attaching the Propionate ester to the hormone, this would allow for the hormone’s release time to be controlled and provided a more efficient means in maintaining stable blood levels. Although this was not the first synthetic testosterone preparation created, Testosterone Propionate would become the first commercially available testosterone product. It would also dominate the medical community until the 1960’s and much of the newly born performance enhancing community.
This medication is used in men who do not make enough of a natural substance called testosterone. In males, testosterone is responsible for many normal functions, including growth and development of the genitals, muscles, and bones. It also helps cause normal sexual development (puberty) in boys. Testosterone belongs to a class of drugs known as androgens. It works by affecting many body systems so that the body can develop and function normally.
Testosterone may also be used in certain adolescent boys to cause puberty in those with delayed puberty. It may also be used to treat certain types of breast cancer in women.
Mechanism of Action:
Endogenous testosterone is responsible for sexual maturation at all stages of development throughout life. Synthetically, it is prepared from cholesterol. The function of androgens in male development begins in the fetus, is crucial during puberty, and continues to play an important role in the adult male. Women also secrete small amounts of testosterone from the ovaries. The secretion of androgens from the adrenal cortex is insufficient to maintain male sexuality.
Increased androgen plasma concentrations suppress gonadotropin-releasing hormone (reducing endogenous testosterone), luteinizing hormone, and follicle-stimulating hormone by a negative-feedback mechanism. Testosterone also affects the formation of erythropoietin, the balance of calcium, and blood glucose. Androgens have a high lipid solubility, enabling them to rapidly enter cells of target tissues. Within the cells, testosterone undergoes enzymatic conversion to 5-alpha-dihydrotestosterone and forms a loosely bound complex with cystolic receptors. Androgen action arises from the initiation of transcription and cellular changes in the nucleus brought about by this steroid-receptor complex.
Normally, endogenous androgens stimulate RNA polymerase, resulting in an increased protein production.These proteins are responsible for normal male sexual development, including the growth and maturation of the prostate, seminal vesicle, penis, and scrotum. During puberty, androgens cause a sudden increase in growth and development of muscle, with redistribution of body fat. Changes also take place in the larynx and vocal cords, deepening the voice. Puberty is completed with beard development and growth of body hair. Fusion of the epiphyses and termination of growth is also governed by the androgens, as is the maintenance of spermatogenesis. When endogenous androgens are unavailable, use of exogenous androgens are necessary for normal male growth and development.
