More recently, androgen receptors have been shown to have a second mode of action. As has been also found for other steroid hormone receptors such as estrogen receptors , androgen receptors can have actions that are independent of their interactions with DNA.   Androgen receptors interact with certain signal transduction proteins in the cytoplasm. Androgen binding to cytoplasmic androgen receptors can cause rapid changes in cell function independent of changes in gene transcription, such as changes in ion transport . Regulation of signal transduction pathways by cytoplasmic androgen receptors can indirectly lead to changes in gene transcription, for example, by leading to phosphorylation of other transcription factors.
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).
The wonderful thing about Spa Tanning Tablets is the fact that they are not only safe and effective, but they are all natural organic and FDA approved. With so many tanning options on the market today, the studies and statistics have revealed that tanning tablets are by far the safest means of tanning available today.
