Mibolerone
Mibolerone, also known as dimethylnortestosterone (DMNT) and sold under the brand names Cheque Drops and Matenon, is a synthetic compound, synthetic, oral administration, orally active, and extremely potency (pharmacology), potent anabolic–androgenic steroid (AAS) and a 17α-alkylated anabolic steroid, 17α-alkylated nandrolone (19-nortestosterone) chemical derivative, derivative which was marketed by Upjohn for use as a veterinary drug. It was indicated specifically as an oral treatment for prevention of estrus (heat) in adult female dogs. Side effects Pharmacology Pharmacodynamics Mibolerone has both higher affinity (pharmacology), affinity and greater binding selectivity, selectivity for the androgen receptor (AR) than does the related potent AAS metribolone (17α-methyl-19-nor-δ9,11-testosterone), although potent and significant progestogenic activity remains present. However, another study found that mibolerone and metribolone had similar affinity for the progesterone r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metribolone
Metribolone (developmental code R1881, also known as methyltrienolone) is a synthetic and orally active anabolic–androgenic steroid (AAS) and a 17α-alkylated nandrolone (19-nortestosterone) derivative which was never marketed for medical use but has been widely used in scientific research as a hot ligand in androgen receptor (AR) ligand binding assays (LBAs) and as a photoaffinity label for the AR. More precisely, metribolone is the 17α-methylated derivative of trenbolone. It was investigated briefly for the treatment of advanced breast cancer in women in the late 1960s and early 1970s, but was found to produce signs of severe hepatotoxicity at very low dosages, and its development was subsequently discontinued. Medical uses Metribolone was never approved for medical use, a situation unlikely to change given its liver toxicity even at low doses. It was studied for the potential treatment of advanced breast cancer in women but development was abandoned. Side effects ...

Anabolic Steroid
Anabolic steroids, also known more properly as anabolic–androgenic steroids (AAS), are steroidal androgens that include natural androgens like testosterone as well as synthetic androgens that are structurally related and have similar effects to testosterone. They increase protein within cells, especially in skeletal muscles, and also have varying degrees of virilizing effects, including induction of the development and maintenance of masculine secondary sexual characteristics such as the growth of facial hair, facial and body hair. The word ''anabolic'', referring to anabolism, comes from the Greek ἀναβολή ''anabole'', "that which is thrown up, mound". Androgens or AAS are one of three types of sex hormone agonists, the others being estrogen (medication), estrogens like estradiol (medication), estradiol and progestogens like progesterone (medication), progesterone. AAS were synthesized in the 1930s, and are now used therapeutically in medicine to stimulate muscle g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trestolone
Trestolone, also known as 7α-methyl-19-nortestosterone (MENT), is an experimental androgen/ anabolic steroid (AAS) and progestogen medication which has been under development for potential use as a form of hormonal birth control for men and in androgen replacement therapy for low testosterone levels in men but has never been marketed for medical use. It is given as an implant that is placed into fat. As trestolone acetate, an androgen ester and prodrug of trestolone, the medication can also be given by injection into muscle. Side effects of trestolone include low estrogen levels and associated symptoms such as reduced sexual function and decreased bone mineral density among others. Trestolone is an AAS, and hence is an agonist of the androgen receptor, the biological target of androgens like testosterone. It is also a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progeste ...

Oral Administration
Oral administration is a route of administration where a substance is taken through the mouth. Per os abbreviated to P.O. is sometimes used as a direction for medication to be taken orally. Many medications are taken orally because they are intended to have a systemic effect, reaching different parts of the body via the bloodstream, for example. Oral administration can be easier and less painful than other routes, such as injection. However, the onset of action is relatively low, and the effectiveness is reduced if it is not absorbed properly in the digestive system, or if it is broken down by digestive enzymes before it can reach the bloodstream. Some medications may cause gastrointestinal side effects, such as nausea or vomiting, when taken orally. Oral administration can also only be applied to conscious patients, and patients willing and able to swallow. Terminology ''Per os'' (; ''P.O.'') is an adverbial phrase meaning literally from Latin "through the mouth" or "by mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Testosterone (medication)
Testosterone (T) is a medication and naturally occurring steroid hormone. It is used to treat male hypogonadism, gender dysphoria, and certain types of breast cancer. It may also be used to increase athletic ability in the form of doping. It is unclear if the use of testosterone for low levels due to aging is beneficial or harmful. Testosterone can be used as a gel or patch that is applied to the skin, injection into a muscle, tablet that is placed in the cheek, or tablet that is taken by mouth. Common side effects of testosterone include acne, swelling, and breast enlargement in men. Serious side effects may include liver toxicity, heart disease, and behavioral changes. Women and children who are exposed may develop masculinization. It is recommended that individuals with prostate cancer not use the medication. It can cause harm to the baby if used during pregnancy or breastfeeding. Testosterone is in the androgen family of medications. Testosterone was firs ...

Progesterone (medication)
Progesterone (P4) is a medication and naturally occurring steroid hormone. It is a progestogen and is used in combination with estrogens mainly in hormone therapy for menopausal symptoms and low sex hormone levels in women. It is also used in women to support pregnancy and fertility and to treat gynecological disorders. Progesterone can be taken by mouth, in through the vagina, and by injection into muscle or fat, among other routes. A progesterone vaginal ring and progesterone intrauterine device used for birth control also exist in some areas of the world. Progesterone is well tolerated and often produces few or no side effects. However, a number of side effects are possible, for instance mood changes. If progesterone is taken by mouth or at high doses, certain central side effects including sedation, sleepiness, and cognitive impairment can also occur. The medication is a naturally occurring progestogen and hence is an agonist of the progesterone receptor (PR), t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ligand (biochemistry)
In biochemistry and pharmacology, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. The etymology stems from ''ligare'', which means 'to bind'. In protein-ligand binding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein. The binding typically results in a change of conformational isomerism (conformation) of the target protein. In DNA-ligand binding studies, the ligand can be a small molecule, ion, or protein which binds to the DNA double helix. The relationship between ligand and binding partner is a function of charge, hydrophobicity, and molecular structure. Binding occurs by intermolecular forces, such as ionic bonds, hydrogen bonds and Van der Waals forces. The association or docking is actually reversible through dissociation. Measurably irreversible covalent bonding between a ligand and target molecule is atypical in biological systems. In contrast to the definition ...

Dimethyltrienolone
Dimethyltrienolone (developmental code name RU-2420) is a synthetic, orally active, and extremely potent anabolic–androgenic steroid (AAS) and 17α-alkylated 19-nortestosterone (nandrolone) derivative which was never marketed for medical use. It has among the highest known affinity of any AAS for the androgen (and progesterone) receptors, and has been said to be perhaps the most potent AAS to have ever been developed. Pharmacology Pharmacodynamics Dimethyltrienolone is an extremely potent agonist of the androgen and progesterone receptors and hence AAS and progestogen. In animal bioassays, it was shown to possess more than 100 times the anabolic and androgenic potency of the reference AAS methyltestosterone. The drug is not a substrate for 5α-reductase and so is not potentiated or inactivated in so-called "androgenic" tissues like the prostate gland or skin. It is also not a substrate for aromatase and so has no estrogenic activity. Due to its lack of estr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Normethandrone
Normethandrone, also known as methylestrenolone or methylnortestosterone and sold under the brand name Metalutin among others, is a progestin and androgen/anabolic steroid (AAS) medication which is used in combination with an estrogen in the treatment of amenorrhea and menopausal symptoms in women. It is taken by mouth. Side effects of normethandrone include symptoms of masculinization like acne, increased hair growth, voice changes, and increased sexual desire. It can also cause liver damage. Normethandrone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. It is also a synthetic AAS and hence is an agonist of the androgen receptor, the biological target of androgens like testosterone and dihydrotestosterone (DHT). It has some estrogenic activity as well and no other important hormonal activity. Normethandrone was introduced for medical use by 1957. It is available only ...

Trenbolone
Trenbolone is an androgen and anabolic steroid (AAS) of the nandrolone group which itself was never marketed. Trenbolone ester prodrugs, including trenbolone acetate (brand names Finajet, Finaplix, others) and trenbolone hexahydrobenzylcarbonate (brand names Parabolan, Hexabolan), are or have been marketed for veterinary and clinical use. Trenbolone acetate is used in veterinary medicine in livestock to increase muscle growth and appetite, while trenbolone hexahydrobenzylcarbonate was formerly used clinically in humans but is now no longer marketed. In addition, although it is not approved for clinical or veterinary use, trenbolone enanthate is sometimes sold on the black market under the nickname Trenabol. Uses Veterinary Trenbolone, as trenbolone acetate, improves muscle mass, feed efficiency, and mineral absorption in cattle. Side effects Sometimes human users may experience an event called "tren cough" shortly after or during an injection, where the user experiences a viol ...
