Testosterone can be taken by a variety of different routes of administration. [2] [3] These include oral, buccal, sublingual, intranasal, transdermal (gels, creams, patches, solutions), vaginal (creams, gels, suppositories), rectal (suppositories), by intramuscular or subcutaneous injection (in oil solutions or aqueous suspensions), and as a subcutaneous implant.
Testosterone undecanoate, sold under the brand name Nebido among others, is an androgen and anabolic steroid (AAS) medication that is used mainly in the treatment of low testosterone levels in men, [9][7][10][11][12][13][14] It is taken by mouth or given by injection into muscle. [11][15]
Testosterone can be used as a gel or transdermal patch that is applied to the skin topically, intramuscular injection (IM), buccally (a tablet dissolved between the gum and cheek inside the mouth), or as an oral tablet (tablet swallowed by mouth). [9] Common side effects of testosterone include acne, swelling, and breast enlargement in men. [9]
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 propionate is administered in oil via intramuscular injection. [ 1 ] [ 2 ] It has a relatively short elimination half-life and mean residence time of 2 days and 4 days, respectively. [ 1 ] [ 2 ] As such, it has a short duration of action and must be administered two to three times per week.
Sources: See template. Testosterone cypionate is a prodrug of testosterone and is an androgen and anabolic–androgenic steroid (AAS). That is, it is an agonist of the androgen receptor (AR). Testosterone cypionate is converted by the body to testosterone that has both androgenic effects and anabolic effects; [ 4 ] still, the relative potency ...
An androgen or anabolic steroid ester is an ester of an androgen / anabolic steroid (AAS) such as the natural testosterone or dihydrotestosterone (DHT) or the synthetic nandrolone (19-nortestosterone). Esterification renders AAS into metabolism -resistant prohormones of themselves, improving oral bioavailability, increasing lipophilicity, and ...
When given via depot intramuscular injection, CPA has an elimination half-life of 3 to 4.3 days while 15β-OH-CPA has a half-life of 5.2 days. [2] [8] [10] [199] The duration of action of a single intramuscular injection of CPA is about 14 to 20 days. [38] [36] [37] The serum total clearance of CPA is approximately 2.32 ± 0.38 mL/min/kg.
