Testosterone Undecanoate 150mg
Epiandrosterone is a dehydroepiandrosterone metabolite and a precursor of testosterone and estradiol with hypolipidemic and anabolic property. Epiandrosterone, a potential neurosteroid, appears to bind to the gamma-aminobutyric acid (GABA)/benzodiazepine-receptor complex (GABA-RC), acting as a negative non-competitive modulator of GABA-RC as well as signal through the N-methyl-D-aspartate receptor. In addition this agent inhibits the pentose phosphate pathway (PPP) thereby dilating blood vessels pre-contracted by partial depolarization. Also, epiandrosterone inhibits the synthesis of thromboxane A2 in activated platelets, reduces plasma plasminogen activator inhibitor type 1 and tissue plasminogen activator antigen, increases serum levels of insulin-like growth factor 1 and increases cyclic guanosine monophosphate and nitric oxide synthesis. These effects may improve circulation in the microvasculature.
NCI Thesaurus (NCIt)
Epiandrosterone is a 3beta-hydroxy steroid that is (5alpha)-androstane substituted by a beta-hydroxy group at position 3 and an oxo group at position 17. It has a role as an androgen and a human metabolite. It is a 17-oxo steroid, a 3beta-hydroxy steroid and an androstanoid. It derives from a 5alpha-androstane.
Androsterone is a steroid metabolite derived from sex hormones, which displays weak androgenic properties. In testes is formed from progesterone. Androsterone sulfate is clinically recognized as one of the major androgen metabolites found in urine, in males and females. It is made in the liver from the metabolism of testosterone. Androsterone glucuronide, a dihydrotestosterone metabolite, is present in serum. Androsterone is a weak anabolic hormone. (NCI04)
NCI Thesaurus (NCIt)
Androsterone is an inactive breakdown metabolite of testosterone, the product of a reaction mediated by the enzyme oxidative 17beta-hydroxysteroid dehydrogenase (EC 1. 1. 1. 51, 17beta-HSD). Androsterone can also be metabolized from other adrenal androgens such as dehydroepiandrosterone, dihydrotestosterone, or androstenedione, and is considered an inactive end product. However, it can be a physiological effector in its own right. Androsterone might be converted back to dihydrotestosterone. Humans (and other primates) are unique among mammals in having high levels of circulating androsterone glucuronide, a process that is the major role of uridine-diphospho-glucuronosyltransferase enzymes (EC 2. 4. 1. 17, UGT) for glucuronidation of steroid metabolism in humans. Conjugation of androsterone is a pathway found in all vertebrates and it is widely recognized that the liver is a major site of glucuronidation. However, it is now clear that extrahepatic tissues are also involved in the conjugation of compounds to which these tissues are exposed. High levels of androsterone glucuronide found in the human prostate, breast cyst fluid, and ovary follicular fluid suggest that glucuronidation of 5alpha-reduced C19 steroids occurs in these tissues as well. In doping control, the ratio of androsterone/etiocholanolone provides valuable information that allows the assignment of a urine specimen to a particular person or the identification of urine samples with identical steroid profiles; this is particularly important to detect attempts of urine manipulation including urine alteration and substitution (PMID: 9188497, 17017935, 14643063, 12943709, 9699884, 17260133).
Human Metabolome Database (HMDB)
Androsterone is an androstanoid that is 5alpha-androstane having a hydroxy substituent at the 3alpha-position and an oxo group at the 17-position. It is a metabolite of dehydroepiandrosterone. It has a role as an androgen, a human metabolite and a mouse metabolite. It is a 3alpha-hydroxy steroid, a 17-oxo steroid, an androstanoid and a C19-steroid. It derives from a hydride of a 5alpha-androstane.
Testosterone undecanoate :
Testosterone undecanoate, sold for use by mouth under the brand names Andriol and Jatenzo and for use by injection under the brand names Aveed and Nebido, is an androgen and anabolic steroid (AAS) medication which is used mainly in the treatment of low testosterone levels in men. which includes hormone therapy for transgender men.It is taken by mouth two to three times per day with food or given by injection into muscle once every 3.5 days to 2 weeks, depending on individual response.
Side effects of testosterone undecanoate include symptoms of masculinization like acne, increased hair growth, voice changes, hypertension, elevated liver enzymes, hypertiglyceridemia, and increased sexual desire.The drug is a prodrug of testosterone, the biological ligand of the androgen receptor (AR) and hence is an androgen and anabolic steroid.It has strong androgenic effects and moderate anabolic effects, which make it useful for producing masculinization and suitable for androgen replacement therapy.Testosterone undecanoate is a testosterone ester and a prodrug of testosterone in the body.Because of this, it is considered to be a natural and bioidentical form of testosterone.
Testosterone undecanoate was introduced in China for use by injection and in Europe for use by mouth in the 1970s.It became available for use by injection in Europe in the early to mid 2000s and in the United States in 2014.A formulation for use by mouth is not currently available in the United States but is pending approval as of 2018.Along with testosterone enanthate, testosterone cypionate, and testosterone propionate, testosterone undecanoate is one of the most widely used testosterone esters.However, it has advantages over other testosterone esters in that it can be taken by mouth and in that it has a far longer duration when given by injection.In addition to its medical use, testosterone undecanoate is used to improve physique and performance.The drug is a controlled substance in many countries and so non-medical use is generally illicit.
