DimethyltrienoloneDimethyltrienolone (developmental code name RU-2420) is a synthetic, orally active, and extremely potent anabolic–androgenic steroid (AAS) and 17α-alkylated 19-nortestosterone (nandrolone) derivative which was never marketed for medical use. It has among the highest known affinity of any AAS for the androgen (and progesterone) receptors, and has been said to be perhaps the most potent AAS to have ever been developed. Dimethyltrienolone is an extremely potent agonist of the androgen and progesterone receptors and hence AAS and progestogen.
Etynodiol diacetateEtynodiol diacetate, or ethynodiol diacetate, sold under the brand names Demulen and Femulen among others, is a progestin medication which is used in birth control pills. The medication is available only in combination with an estrogen. It is taken by mouth. Etynodiol diacetate is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. It has weak androgenic and estrogenic activity and no other important hormonal activity.
LynestrenolLynestrenol, sold under the brand names Exluton and Ministat among others, is a progestin medication which is used in birth control pills and in the treatment of gynecological disorders. The medication is available both alone and in combination with an estrogen. It is taken by mouth. Lynestrenol is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. It has weak androgenic and estrogenic activity and no other important hormonal activity.
Dimethandrolone undecanoateDimethandrolone undecanoate (DMAU), also known by its developmental code name CDB-4521, is an experimental androgen/anabolic steroid (AAS) and progestogen medication which is under development as a potential birth control pill for men. It is taken by mouth, but can also be given by injection into muscle. Side effects of DMAU include mild weight gain and mild decreases in levels of HDL cholesterol. It may also cause low estrogen levels and associated symptoms such as reduced sexual function and decreased bone mineral density.
TiboloneTibolone, sold under the brand name Livial among others, is a medication which is used in menopausal hormone therapy and in the treatment of postmenopausal osteoporosis and endometriosis. The medication is available alone and is not formulated or used in combination with other medications. It is taken by mouth. Side effects of tibolone include acne and increased hair growth among others. Tibolone is a synthetic steroid with weak estrogenic, progestogenic, and androgenic activity, and hence is an agonist of the estrogen, progesterone, and androgen receptors.
