LGD-3303 is a non-steroidal selective androgen receptor modulator (SARM) that stands out for its pronounced effects on bone as well as muscle. In rodent studies it raised bone mineral density, stimulated new bone formation, and increased muscle mass while keeping prostate stimulation low, and it even added to the benefit of a standard bone drug. Orally active and strongly tissue-selective, LGD-3303 has a distinctive physique-and-bone profile that keeps it firmly on the radar of SARM research.
Superdrol, known generically as methasterone, is a synthetic, orally active anabolic-androgenic steroid derived from dihydrotestosterone. First prepared in the 1950s but never developed as a medicine, it later resurfaced as a designer steroid sold over the counter as a bodybuilding supplement. It is now a controlled substance and is noted chiefly for pronounced liver toxicity.
Testosterone is the principal androgen and male sex hormone, a C19 steroid produced mainly by the Leydig cells of the testes in men and in smaller amounts by the ovaries and adrenal glands in women. It drives development of male reproductive tissue and secondary sexual characteristics and supports muscle and bone mass, red-blood-cell production, libido, and sperm formation. Synthesized in the body from cholesterol, testosterone is also manufactured as a medicine, used chiefly as replacement therapy for male hypogonadism, and is regulated as an anabolic-androgenic steroid because of its potential for misuse [1].
Testosterone undecanoate is a long-chain fatty acid ester of testosterone taken as an oral softgel; it is absorbed through intestinal lymphatics rather than the portal vein, which is what lets an oral androgen work at all.
Anadrol is a brand name for oxymetholone, a synthetic anabolic-androgenic steroid derived from dihydrotestosterone. Introduced in the early 1960s, it is used medically to treat certain anemias by stimulating red blood cell production, and historically for conditions involving muscle wasting. Because it is 17-alpha-alkylated it can be taken by mouth, but it carries a notable risk of liver toxicity, and in many countries it is a controlled substance often misused for physique and performance enhancement.
Anavar is a brand name for oxandrolone, a synthetic anabolic-androgenic steroid developed in the early 1960s. A derivative of dihydrotestosterone with an oxygen atom substituted into its steroid ring, it is taken by mouth and is known for a relatively high ratio of anabolic to androgenic activity. It has been used medically to help patients regain weight after trauma, surgery, or severe burns and in other catabolic conditions, and it is also misused for physique and performance enhancement.
Androsterone (3α-hydroxy-5α-androstan-17-one) is an endogenous androstane neurosteroid (a steroid synthesized or acting within the nervous system) and a peripheral metabolite of testosterone and dehydroepiandrosterone. Like its pregnane counterpart allopregnanolone, it acts as a positive allosteric modulator (an agent that enhances a receptor's response to its natural transmitter) of the GABA-A receptor (the brain's principal inhibitory ion channel), producing barbiturate-like potentiation of inhibitory neurotransmission. In rodent studies it raises seizure threshold across multiple models and is regarded as an endogenous modulator of neuronal excitability; because native androsterone is rapidly conjugated and orally poorly available, a prodrug (an inactive precursor that converts to the active drug in the body) has been investigated for epilepsy.
Metandienone, more widely known by the former brand name Dianabol, is an orally active anabolic-androgenic steroid, a synthetic relative of the male hormone testosterone. Developed in the 1950s, it was among the first such steroids to be used widely by athletes and bodybuilders to build muscle and enhance performance. It has largely been withdrawn from legitimate medical use and is now encountered mainly as a non-medical performance-enhancing drug. In the United States and many other countries it is a controlled substance and is banned in competitive sport.
Dihydroboldenone (DHB), also known as 1-testosterone, is an anabolic-androgenic steroid; chemically it is the 5-alpha-reduced form of boldenone and a close relative of DHT. It is used in bodybuilding circles for lean, dry muscle gains and strength without estrogen conversion. It has a reputation for strong anabolic activity and, like most injectable steroids, for causing painful injection sites. It is a controlled substance in many countries and is not a supplement.
Equipoise is a brand name for boldenone undecylenate, an anabolic-androgenic steroid given by injection. Chemically it is the undecylenate ester of boldenone, a synthetic relative of testosterone, and it works as a long-acting prodrug that releases boldenone slowly in the body. Once used briefly in human medicine, it is today marketed mainly for veterinary use in horses and is also used non-medically for muscle building. In many countries it is a controlled substance and is banned in competitive sport.
Masteron is a brand name for drostanolone, a synthetic anabolic-androgenic steroid derived from dihydrotestosterone (DHT). Introduced around 1960 and once used medically, chiefly as a secondary treatment for breast cancer in women, it is now encountered mainly as a non-medical performance and physique-enhancing drug and is a controlled substance in many countries [1][2]. It is usually supplied as an injectable ester such as drostanolone propionate, and because it derives from DHT it cannot be converted into estrogen [1].
Nandrolone, chemically 19-nortestosterone, is an anabolic-androgenic steroid closely related to testosterone. Usually given as a long-acting ester such as nandrolone decanoate (Deca-Durabolin), it has been used medically for conditions involving muscle wasting, anemia, and osteoporosis, and it is also one of the most widely misused steroids in bodybuilding and sport. It is a controlled substance in many countries and has been banned in athletic competition for decades.
Primobolan is a brand name for metenolone (also spelled methenolone), an anabolic-androgenic steroid derived from dihydrotestosterone (DHT). It is sold in two forms, an oral acetate (Primobolan) and an injectable enanthate (Primobolan Depot), and medically it has been used mainly to treat certain anemias and muscle-wasting conditions. Metenolone produces modest muscle-building effects with relatively weak androgenic activity and, unlike many oral steroids, does not convert to estrogen and is not notably toxic to the liver; it is a controlled substance in many countries and is banned in sport.
Trenbolone is a synthetic anabolic-androgenic steroid derived from nandrolone, developed for veterinary use to promote growth in cattle and never approved for humans [1][4]. It is a potent agonist of the androgen receptor and is used illicitly by some bodybuilders and athletes to build muscle, despite being a controlled substance in many countries [1]. It is typically administered as ester prodrugs such as trenbolone acetate.
Chlorodehydromethyltestosterone, sold as Oral Turinabol and often shortened to turinabol, is a synthetic anabolic-androgenic steroid taken by mouth. It is a chlorinated derivative of metandienone (Dianabol), designed to separate anabolic muscle-building effects from androgenic ones. Developed by the East German firm Jenapharm in the 1960s, it became notorious as the central drug of the state-sponsored doping of athletes in the former German Democratic Republic [1][2].
Winstrol is a brand name for stanozolol, a synthetic anabolic-androgenic steroid derived from dihydrotestosterone. It is distinguished by a pyrazole ring fused to the steroid A-ring and by 17-alpha-alkylation, a modification that lets it remain active when taken by mouth. Introduced in 1962, it has been used medically for conditions such as hereditary angioedema and certain anemias, and it also became one of the most notorious performance-enhancing drugs in sport.
