NET is a potent progestogen and binds to the PR with approximately 150% of the affinity of progesterone . [3] In contrast, its parent compounds, testosterone , nandrolone (19-nortestosterone), and ethisterone (17α-ethynyltestosterone), have 2%, 22%, and 44% of the relative binding affinity of progesterone for the PR. [5] Unlike NET, its major active metabolite 5α-dihydro-NET (5α-DHNET), which is formed by 5α-reductase , has been found to possess both progestogenic and marked antiprogestogenic activity, [26] although its affinity for the PR is greatly reduced relative to NET at only 25% of that of progesterone. [3] NET produces similar changes in the endometrium and vagina and is similarly thermogenic in women compared to progesterone, which is in accordance with its progestogenic activity. [27]

Valproic acid was first synthesized in 1882 by Beverly S. Burton as an analogue of valeric acid , found naturally in valerian . [66] Valproic acid is a carboxylic acid , a clear liquid at room temperature. For many decades, its only use was in laboratories as a "metabolically inert" solvent for organic compounds. In 1962, the French researcher Pierre Eymard serendipitously discovered the anticonvulsant properties of valproic acid while using it as a vehicle for a number of other compounds that were being screened for antiseizure activity. He found it prevented pentylenetetrazol -induced convulsions in laboratory rats . [67] It was approved as an antiepileptic drug in 1967 in France and has become the most widely prescribed antiepileptic drug worldwide. [68] Valproic acid has also been used for migraine prophylaxis and bipolar disorder. [69]

In contrast, Julio Collazos, ., of Hospital de Galdakao in Vizcaya and colleagues reported in the April 12, 2002 issue of AIDS that in a study of nearly 200 clinically stable HIV-positive men (average CD4 cell count 451 cells/mm 3 ; 64% with undetectable viral load ), most subjects had testosterone levels within the normal range. Men receiving no anti-HIV therapy had the lowest testosterone, while those using a regimen combining three classes of antiretroviral drugs had the highest levels. Among the 15 men who had both pre- and post-treatment testosterone measurements, levels increased after starting HAART. But because testosterone levels normally begin to decline around age 40 (a phenomenon known as "andropause"), the beneficial effects of HAART on hypogonadism may be offset as treatment enables HIV-positive men to live to older ages.

Laws and Penalties:  Concerns over growing illegal AAS abuse by teenagers, and many of the just discussed long-term effects, led Congress in 1991 to place the whole AAS class of drugs into Schedule III of the Controlled Substances Act (CSA).  Under this legislation, AAS are defined as any drug or hormonal substance, chemically and pharmacologically related to T (other than estrogens, progestins, and corticosteroids) that promotes muscle growth.  The possession or sale of AAS without a valid prescription is illegal.  Since 1991, simple possession of illegally obtained AAS carry a maximum penalty of one year in prison and a minimum $1,000 fine if this is an individual’s first drug offense.  The maximum penalty for trafficking (selling or possessing enough to be suspected of selling) is five years in prison and a fine of $250,000 if this is the individual’s first felony drug offense.  If this is the second felony drug offense, the maximum period of imprisonment and the maximum fine both double.  While the above listed penalties are for federal offenses, individual states have also implemented fines and penalties for illegal use of AAS.  State executive offices have also recognized the seriousness of AAS abuse and other drugs of abuse in schools. For example, the State of Virginia enacted a law that will allow student drug testing as a legitimate school drug prevention program (48, 49).
