Estradiol levels after a short intravenous infusion of 20 mg estradiol in aqueous solution or an intramuscular injection of an equimolar dose of estradiol benzoate, estradiol valerate, or estradiol undecylate in oil solution in women. [6] [7] Sources: Geppert (1975) and Leyendecker et al. (1975). [6] [7]
Levels of testosterone with intramuscular injections of testosterone cypionate were about 700 ng/dL for 100 mg/week, 1100 ng/dL for 250 mg/week, and 2000 ng/dL for 500 mg/week. [75] [76] In another study, testosterone levels with 600 mg/week testosterone enanthate by intramuscular injection were 2,800–3,200 ng/dL. [75] [77]
Intramuscular injection, often abbreviated IM, is the injection of a substance into a muscle. In medicine , it is one of several methods for parenteral administration of medications. Intramuscular injection may be preferred because muscles have larger and more numerous blood vessels than subcutaneous tissue, leading to faster absorption than ...
Testosterone levels increase in adolescence after puberty and into early adulthood, and naturally decline over time, usually starting in a man’s 40s or fifties. However, this drop now seems to ...
Estradiol and testosterone levels after an intramuscular injection of 1 mg estradiol benzoate, 7.5 mg estradiol dienanthate, and 150 mg testosterone enanthate benzilic acid hydrazone in oil (brand name Climacteron) in ovariectomized women. [1] Assays were performed using immunoassays. [1] Source was Sherwin (1987). [1]
Androgen replacement therapy (ART), often referred to as testosterone replacement therapy (TRT), is a form of hormone therapy in which androgens, often testosterone, are supplemented or replaced. It typically involves the administration of testosterone through injections, skin creams, patches, gels, pills, or subcutaneous pellets.
Hormone levels following a single intramuscular injection of EV/NETE (5 mg/50 mg) in healthy young men. [9] Testosterone levels were maximally suppressed by about 94%, to ~30 ng/dL, when measured at day 7. [9] EV/NETE is a combination of EV, an estrogen, and NETE, a progestogen with weak androgenic activity.
Testosterone enanthate has an elimination half-life of 4.5 days and a mean residence time of 8.5 days when used as a depot intramuscular injection. [2] It requires frequent administration of approximately once per week, and large fluctuations in testosterone levels result with it, with levels initially being elevated and supraphysiological. [2]
