Steroids have an important role in growth, development, sexual differentiation and reproduction. All four classes of steroids, androgens, oestrogens, progestogens and glucocorticoids, have varying effects on the brain.
Steroid numbering system and nomenclature. All steroids are related to a characteristic molecular structure composed of 17 carbon atoms—arranged in four rings conventionally denoted by the letters A, B, C, and D—bonded to 28 hydrogen atoms.
There are five major classes of steroid hormones: testosterone (androgen), estradiol (estrogen), progesterone (progestin), cortisol/corticosterone (glucocorticoid), and aldosterone (mineralocorticoids).
The steroids that are made almost exclusively in the adrenal glands are cortisol, 11-deoxycortisol, aldosterone, corticosterone, and 11-deoxycorti-costerone. Most other steroid hormones, including the estrogens, are made by the adrenal glands and the gonads [1].
Testosterone, trenbolone, oxymetholone, methandrostenolone, nandrolone, stanozolol, boldenone, and oxandrolone are some of the anabolic steroids that are most commonly encountered by United States law enforcement.
Testosterone. Available in both oral and injectable forms, testosterone is widely prescribed to treat low testosterone levels and is considered the safest oral steroid.
Cholesterol. The best known and most abundant steroid in the body is cholesterol. Cholesterol is formed in brain tissue, nerve tissue, and the blood stream. It is the major compound found in gallstones and bile salts.
The most important steroid is cholesterol : other steroids are derived from it biologically and it is the most common steroid in the human body.

Glucocorticoids, naturally occurring and synthetic, are adrenocortical steroids that are readily absorbed from the gastrointestinal tract. Glucocorticoids cause varied metabolic effects. In addition, they modify the body's immune responses to diverse stimuli.
Six steroid hormones (androstenediol (AEDOL), estradiol (E2), dehydroepiandrosterone (DHEA), dihydrotestosterone (DHT), pregnenolone (P5), and progesterone (P4)) demonstrated metabolic interaction with HDL, particularly HDL3.
The two main types are corticosteroids and anabolic-androgenic steroids (or anabolics for short).
Tren is a powerful anabolic steroid that can help you build muscle mass and increase strength. However, it is also important to note that tren can have some potentially dangerous side effects, so it is essential to consult with a doctor before taking it or any other type of steroid.
Trenbolone can be the most powerful anabolic steroids available for bodybuilders, and many experts believe it is the most effective anabolic steroids. It is one of the most efficient substances that has applications ranging from bodybuilding to performance improvement.
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.
Prednisone has long-lasting effects and is usually prescribed once daily.
Here's a list of some of the most common anabolic steroids taken today: anadrol, oxandrin, dianabol, winstrol, deca-durabolin, and equipoise.
2) In spite of its positive effectiveness, long term use of steroid can cause adverse effects, including osteoporosis, renal impairment, infection, gastrointestinal disorder, depression, hypertension and diabetes.
Anabolic steroids are drugs that athletes take to boost their strength and add muscle. These drugs also are called anabolic-androgenic steroids. They are made to work like a hormone that the body makes called testosterone.
If taken orally, steroids can show up in a urine test for up to 14 days. If injected, steroids can show up for up to 1 month.
Natural steroids typically refer to compounds found in plants, herbs, and other natural sources that mimic human hormones or steroids. Supporters of natural steroids claim they act in the body like anabolic steroids. These are compounds that build and repair muscle by increasing the production of testosterone.
