To answer the actualy quation posed, now that we've gotten past the bad grammar and spelling issues:
Steroids (incorrectly named by the common press) refers to a group of compounds that share a multiple similar ring structure, including vitamin D, cholesterol, prednisone, hydrocortisone, estrogen and testosterone. The latter of these (and its analogues) is what the common press is refering to when it says "steroids."
These have bene around far longer than the 1980's, having been brought into existance in this country by Dr. john Ziegler and Ciba labs in the 1950's as an oral testoserone and put intot he hands of the athletic community shortly thereafter. Testosterone was used openly in athletics until the compound was villifed by the US Congress in the late 1980's following a couple of news generating deaths, which were blamed on testosterone but lacked an credible medical evidence (one a former profootball player with a brain tumor who blamed it on steroids---the problem here is taht ofr his claim to ahve held scientifically there would have had to have been a greater incidence of brain or other tumors in the steroid using community than in the regular community at large (and there was not).
In spite of protests to the US Congress made by the American Medical Association, the Drug Enforcement Agency (DEA) and the Food and Drug Administration (FDA), COngress chose to make a political move rather than a scientific one. No stidues had actually benn done on testoterone and the decisions wer being made without an credible evidence.
In 1996 the first of a string of studies on testoerone appeared in medical journals in the USA (New England Journal of Medicine), and it, along with numerous studies since, has not supported the governemtn's position that testosterone is the danger they have made it out to be. Even the famed "roid rage" study was done on rodents.
The other popular fraud sold to the American public is that use of testoerone is cheating. But somehow, speed suits in swimming, specially designed track shoes for running, fiberglass poles for pole vaulting and streoid shots of the antiinflammatory nature (prednisone) do not constitute cheating, You can get a good primer of the double speak of the US Congress and the realities of testosterone use in the documentary "Bigger Stronger Faster: Is it Still Cheating if Everyone is Doing It?"
As far as use goes:
1) There are risks so know what you are doing for a cycle before you start. You have to know how to run a post cycle as well to being your body back into functional balance. Research and learn or you can permenantly ruin your hormone system in your body.
2) HIgh doses should not be done for long periods of time (no more than 10 to 12 weeks at most)
3) Testoerone supplimenting is not a quick fix or easy out to growin muscles fast; it is meant to be used by the seasoned/advanced athlete
4) Along wiht the whole NOT a quick fix notion, use of injected testosterone is not going work unless the muscles are worked so expect to be in the gym lifting hard, eating a lot and resting. If you are hte partying type, you will have limited success, jsut as you would if training testosterone free.
5) Injectiable test is better than oral test due to the molecular alteration needed at the 17th carbon to protect the alcohol molecule on it from premature deatruction by the liver on first pass metabolism. This alteration (usually the addiiton of a methyl group to the 17th carbon) stresses the liver and causes water retention, high liver enzymes and high blood pressure mainly from the water retention). Injectable testosterones (enenthate, cypionate, propionate, deca, equipoise) do not ahve this alteration and do not stress the liver like orals do.
