General Introduction of Testosterone Enanthate


Testosterone enanthate is an ester of the naturally-occurring steroid hormone testosterone. In the body, it is directly involved in the production of semen. As an androgen, it also stimulates muscle growth and increases bone density. It is used for a number of medical purposes, including hormone replacement therapy. Users must inject it directly into the muscle tissue. Typical dosages vary, and individuals must take care to avoid a number of injection site complications.

For males, testosterone entanthate is prescribed for conditions such as primary hypogonadism, hypogonadotropic hypogonadism, and delayed puberty. Doctors may prescribe it for females with metastatic mammary cancer.
 Testosterone Enanthate Testosterone is a steroid hormone from the androgen group and is found in mammals, reptiles, birds, and other vertebrates. In mammals, testosterone is primarily secreted in the testicles of males and the ovaries of females, although small amounts are also secreted by the adrenal glands. It is the principal male sex hormone and an anabolic steroid.

In men, testosterone plays a key role in the development of male reproductive tissues such as the testis and prostate as well as promoting secondary sexual characteristics such as increased muscle, bone mass, and the growth of body hair. In addition, testosterone is essential for health and well-being as well as the prevention of osteoporosis.

On average, an adult human male body produces about 7-8 times more testosterone than an adult human female body, but females are more sensitive to the hormone. Testosterone is observed in most vertebrates. Fish make a slightly different form called 11-ketotestosterone. Its counterpart in insects is ecdysone. These ubiquitous steroids suggest that sex hormones have an ancient evolutionary history.

Explanation of Norethisterone

 Normethisterone

Norethisterone is a man-made form of progesterone, a naturally occurring female sex hormone. It is referred to as a progestogen and it has a number of uses. Low doses are used to prevent pregnancy, or as hormone replacement therapy (HRT). Its is used to treat heavy periods (menorrhagia), and high-strength tablets are sometimes used in some female cancers such as breast cancer. There are a number of other leaflets which will give you more information about norethisterone if you are taking it for contraception or as HRT. These are: 'Progestogen-only contraceptive tablets', 'Norethisterone contraceptive injection', 'Combined hormonal contraceptives', and 'Oestrogen and progestogen for HRT'.

Norethisterone (or norethindrone) (or 19-nor-17α-ethynyltestosterone) is a molecule used in some combined oral contraceptive pills, progestogen only pills and is also available as a stand-alone drug. It is a progestogen and can be used to treat premenstrual syndrome, painful periods, abnormal heavy bleeding, irregular periods, menopausal syndrome (in combination with oestrogen), or to postpone a period.

This leaflet discusses norethisterone when it is used to treat heavy periods. Although other treatment options for heavy periods are more common, norethisterone is sometimes considered if other treatments have not worked or are unsuitable. Norethisterone treatment aims to reduce the amount of blood loss. When taking norethisterone in this way, it does not act as a contraceptive.

In the United States possession or use of Trenbolone for humans is a violation of federal law. The DEA classifies Trenbolone as a schedule III drug. Trenbolone in the United Kingdom. Use or possession of steroids without a prescription is a crime in Australia.

Trenbolone acetate is often referred to as "Fina" by users, because injectible trenbolone acetate is often prepared from Finaplix H pellets, an ear implant used by cattle ranchers to maintain the weight of cattle during shipping to slaughter. Studies have shown that Trenbolone does improve muscle mass in cattle.

Veterinary Uses of Trenbolone Acetate

 Trenbolone Acetate

Trenbolone is a steroid used by veterinarians on livestock to increase muscle growth and appetite. To increase its effective half-life, trenbolone is not used in an unrefined form, but is rather administered as ester derivatives such as trenbolone acetate, trenbolone enanthate or trenbolone cyclohexylmethylcarbonate (Parabolan). Plasma lipases then cleave the ester group in the bloodstream leaving free trenbolone.

A powerful mass builder and perfect for increasing strength, trenbolone acetate has the ability to strip body-fat and promote conditioning unlike most any other anabolic androgenic steroid; in-fact, while a superior bulking steroid it will be in a cutting cycle where trenbolone acetate truly shines.

Trenbolone acetate is intended for use in beef cattle. Farmers use it to increase the cow's muscle mass and overall weight. Additionally, it makes the cow's digestive use of feed more efficient. Trenbolone acetate is administered via a special gun that injects pellets of trenbolone underneath the cow's skin. It is injected shortly before slaughter to decrease the loss of muscle and weight during transportation to slaughterhouses.

Trenbolone is a steroid used by veterinarians on livestock to increase muscle growth and appetite. To increase its effective half-life, trenbolone is not used in an unrefined form, but is rather administered as ester derivatives such as trenbolone acetate, trenbolone enanthate or trenbolone cyclohexylmethylcarbonate (Parabolan). Plasma lipases then cleave the ester group in the bloodstream leaving free trenbolone.

 Trenbolone Enanthate
Trenbolone enanthate is a drug that is exclusive to the underground market. In other words, people won’t see it with the Organon or STERIS label on it. It was produced as a cheaper alternative to Parabolan, by a leading underground lab several years ago. Trenbolone enanthate (or any form of Trenbolone) aids anabolism by promoting nitrogen retention and protein synthesis in muscles, and it seems to interact strongly with the receptors of anti-anabolic (muscle growth preventing) glucocorticoid hormones. This will reduce cortisol and aid in muscle growth. Due to these protein synthesizing effects, it can aid your feed efficiency and mineral absorption which will make food you eat more productive in building new muscle tissue, and makes it a very effective agent with regards to nutrient partitioning, which is how your body metabolizes foodstuffs.

Trenbolone enanthate is an injectable steroid containing 200mgs per ML of the hormone Trenbolone Enanthate.
