Peptides (from Ancient Greek πεπτός (peptós) 'digested', from πέσσειν (péssein) 'to digest') are short chains of amino acids linked by peptide bonds. Chains of fewer than twenty amino acids are called oligopeptides, and include dipeptides, tripeptides , and tetrapeptides.Selective Androgen Receptor Modulators or SARMs are a class of androgen receptor ligands that maintain some of the desirable effectsTestosterone is the primary sex hormone and anabolic steroid in males. In humans, testosterone plays a key role in the development Nandrolone, also known as 19-nortestosterone, is an androgen and anabolic steroid (AAS) which is used in the form of esters such asNandrolone, also known as 19-nortestosterone, is an androgen and anabolic steroid (AAS) which is used in the form of esters such as nandrolone decanoate (brand name Deca-Durabolin) and nandrolone phenylpropionate (brand name Durabolin). Nandrolone esters are used in the treatment of anemias, cachexia (wasting syndrome), osteoporosis, breast cancer, and for other indications. They are not used by mouth and instead are given by injection into muscle or fat. Side effects of nandrolone esters include symptoms of masculinization like acne, increased hair growth, voice changes, and decreased sexual desire due to its ability to suppress endogenous testosterone synthesis while not being a sufficient androgen itself. They are synthetic androgens and anabolic steroids and hence are agonists of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). Nandrolone has strong anabolic effects and weak androgenic effects, which give them a mild side effect profile and make them especially suitable for use in women and children. There are metabolites of Nandrolone that act as long-lasting prodrugs in the body, such as 5α-Dihydronandrolone.

Boldenone (developmental code name RU-18761), is a naturally occurring anabolic–androgenic steroid (AAS) and the 1(2)-dehydrogenated analogue of testosterone. Boldenone itself has never been marketed; as a pharmaceutical drug, it is used as boldenone Trenbolone is an androgen and anabolic steroid (AAS) of the nandrolone group which itself was never marketed. Trenbolone ester prodrugsMetenolone, or methenolone, is an androgen and anabolic steroid (AAS) which is used in the form of esters such as metenolone acetateDrostanolone, 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.
