Nandrolone, also known as 19-nortestosterone, is an androgen and anabolic steroid (AAS) which is used in the form of esters such as decanoate (brand name Deca-Durabolin) and phenylpropionate (brand name Durabolin).

Boldenone can increase nitrogen retention, protein synthesis, increases appetite and stimulates the release of erythropoietin in the kidneys.

Methyl-1-testosterone (M1T; developmental code name SC-11195), also known as 17α-methyl-4,5α-dihydro-δ1-testosterone (17α-methyl-δ1-DHT) or 17α-methyl-5α-androst-1-en-17β-ol-3-one, as well as methyldihydroboldenone, is a synthetic and orally active anabolic–androgenic steroid (AAS) which was never marketed for medical use. It is the 17α-methyl derivative of 1-testosterone (Δ1-DHT; dihydroboldenone

Metribolone (developmental code name 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.

Methyltestosterone, sold under the brand names Android, Metandren, and Testred among others, is an androgen and anabolic steroid (AAS) medication which is used in the treatment of low testosterone levels in men, delayed puberty in boys, at low doses as a component of menopausal hormone therapy for menopausal symptoms like hot flashes, osteoporosis, and low sexual desire in women, and to treat breast cancer in women.

Metenolone acetate, or methenolone acetate, sold under the brand names Primobolan and Nibal, is an androgen and anabolic steroid (AAS) medication which is used mainly in the treatment of anemia due to bone marrow failure.

Methasterone resurfaced in 2005 as a “designer steroid”. It was brought to market by Designer Supplements as the primary ingredient of a dietary supplement named Superdrol.

Metandienone, also known as methandienone or methandrostenolone and sold under the brand name Dianabol among others, is an androgen and anabolic steroid (AAS) medication. Metandienone was originally developed in 1955 by CIBA and marketed in Germany and the United States. As the CIBA product Dianabol, metandienone quickly became the first widely used AAS among professional and amateur athletes, and remains the most common orally active AAS for non-medical use. It is currently a controlled substance in the United States and United Kingdom and remains popular among bodybuilders. Metandienone is readily available without a prescription in certain countries such as Mexico, and is also manufactured in some Asian countries.

Mesterolone is an androgen and anabolic steroid (AAS) medication which is used mainly in the treatment of low testosterone levels.

Mestanolone is an androgen and anabolic steroid (AAS) medication.

Letrozole is an aromatase inhibitor which is used in the treatment of hormonally-responsive breast cancer after surgery.

Fluoxymesterone, sold under the brand names Halotestin and Ultandren among others, is an androgen and anabolic steroid (AAS) medication which is used in the treatment of low testosterone levels in men, delayed puberty in boys, breast cancer in women, and anemia.

Exemestane, sold under the brand name Aromasin among others, is a medication used to treat breast cancer. It is a member of the class of antiestrogens known as aromatase inhibitors. Some breast cancers require estrogen to grow. Those cancers have estrogen receptors (ERs), and are called ER-positive. They may also be called estrogen-responsive, hormonally-responsive, or hormone-receptor-positive. Aromatase is an enzyme that synthesizes estrogen. Aromatase inhibitors block the synthesis of estrogen. This lowers the estrogen level, and slows the growth of cancers.

Drostanolone, or dromostanolone, is an anabolic–androgenic steroid (AAS) of the dihydrotestosterone (DHT) group which was never marketed.An androgen ester prodrug of drostanolone, drostanolone propionate, was formerly used in the treatment of breast cancer in women under brand names such as Drolban, Masteril, and Masteron.This has also been used non-medically for physique- or performance-enhancing purposes.

Dehydroepiandrosterone (DHEA), also known as androstenolone, is an endogenous steroid hormone precursor.It is one of the most abundant circulating steroids in humans.
