Pregnenolone (3β-hydroxypregn-5-en-20-one), also known as P5, is an endogenous steroid hormone. It is the precursor of the progestogens, mineralocorticoids, glucocorticoids, androgens, and estrogens, as well as the neuroactive steroids. In addition, pregnenolone is biologically active in its own right, acting as a neurosteroid. Like other steroids, pregnenolone consists of four interconnected cyclic hydrocarbons. It contains ketone and hydroxyl functional groups, …

17-Hydroxyprogesterone (17-OHP) is an endogenous progestogen as well as chemical intermediate in the biosynthesisof othersteroid hormones, including the corticosteroids and the androgens and the estrogens. It is derived from progesterone via 17-hydroxylase, a P450c17 enzyme, or from 17-hydroxypregnenolone via 3β-hydroxysteroid dehydrogenase isomerase. 17-OHP increases in the third trimester of pregnancy primarily due to fetal adrenal production.This steroid is primarily produced …

Progesterone is a female Progesterone Hormones important for the regulation of ovulation and menstruation.Women take progesterone by mouth for inducing menstrual periods who have not yet reached menopause but are not having periods due to a lack of progesterone in the body; And treating abnormal uterine bleeding associated with hormonal imbalance, and severe symptoms of premenstrual syndrome (PMS). Progesterone is …

Estradiol Valerate is the parenterally-administered synthetic valerate ester of estradiol, a steroid sex hormone vital to the maintenance of fertility and secondary sexual characteristics in females. As the primary, most potent estrogen hormone produced by the ovaries, estradiol binds to and activates specific nuclear receptors. This agent exhibits mild anabolic and metabolic properties, and increases blood coagulability. Estradiol Valerate is …

Estradiol (called α – estradiol or 17α – estradiol) for human breast cancer cells in tissue culture biologically active estrogen. Not part of the 17- and selective estrogen receptor (ER-X) traditional hormone / receptor of the endocrine system, but an important autocrine / paracrine function of the system is part of the growth in the adult brain. In menopause, and …

Estradiol Benzoate is a sex hormone that is present in both males and females, and is the most important form of estrogen in humans. In women, it plays a key role in the development and functioning of the reproductive system, as well as in the growth of certain bones. It also governs the distribution of body fat in women and …

Estradiol being a sex hormone. With alpha, beta, two types of alpha physiological function is strong. Steiner, winter was extracted from the horse urine pregnancy, moreover also can cause from the urine, placenta, pig ovary, etc. There is also a male horse testis or urine. Because it has the very strong sex role, so that it or its ester is, …

4-Androstenediol, also known as androst-4-ene-3β,17β-diol, is an androstenediol that is converted to testosterone. The conversion rate is about 15.76%, almost triple that of 4-androstenedione, due to utilization of a different enzymatic pathway. There is also some conversion into estrogen, since testosterone is the metabolic precursor of the estrogens. 4-Androstenediol is closer to testosterone structurally than 5-androstenediol, and has androgenic effects, …

Methyldiazinol (also known as 3,3-azo-17α-methyl-5α-dihydrotestosterone, 3-azi-17α-methyl-DHT, or 3,3-azo-17α-methyl-5α-androstan-17β-ol) is a synthetic and orally active androgen/anabolic steroid (AAS) which was never marketed.It is a 17α-methylated derivative of dihydrotestosterone (DHT); specifically, it is the C3 azi (i.e., 3,3-azo) analogue of mestanolone (17α-methyl-DHT).The drug has been found to possess a high ratio and dissociation of myotrophic to androgenic activity; relative to methyltestosterone, its …
