By October 1945, DDT was available for public sale in the United States, used both as an agricultural pesticide and as a household insecticide.  Although its use was promoted by government and the agricultural industry, US scientists such as FDA pharmacologist Herbert O. Calvery expressed concern over possible hazards associated with DDT as early as 1944.    As its production and use increased, public response was mixed. At the same time that DDT was hailed as part of the "world of tomorrow," concerns were expressed about its potential to kill harmless and beneficial insects (particularly pollinators ), birds, fish, and eventually humans. The issue of toxicity was complicated, partly because DDT's effects varied from species to species, and partly because consecutive exposures could accumulate, causing damage comparable to large doses. A number of states attempted to regulate DDT.   In the 1950s the federal government began tightening regulations governing its use.  These events received little attention. Women like Dorothy Colson and Mamie Ella Plyler of Claxton, Georgia gathered evidence about DDT's effects and wrote to the Georgia Department of Public Health, the National Health Council in New York City, and other organizations. 
As for individual use of a personal nature, outside therapeutic treatment, this is where we will find the vast majority of anabolic steroids. It is here we will also find the biggest problems, not in terms of ill-effects of a physical or mental nature but of those surrounding legality. In places like the . anabolic steroids are controlled substances, and here we will find the strictest of laws. This has created a new class of criminal; most commonly an adult man with a family who is simply living an every day life like everyone else. These are issues that need to be discussed and you will find very few are willing to touch them unlike .
It is very common for bodybuilders to use veterinary steroids for a precontest cycle. Since they are typically assimilated quickly, they do the best work in the shortest amount of time, and are generally out of the system relatively fast in comparison to other ‘roids. And, believe it or not, usually people see fewer side effects when using vet products than when using human ones. Why take anything else? Maybe not ‘why take anything else’, but why not include veterinary steroids, in one form or another, in every cycle? In my mind, veterinary drugs should really be everyone’s choice for extreme condition and definition. They combine well with androgens and other anabolics as well as any drug in the human realm of anabolic steroids. The only problem, these days anyway, is availability. You can find them in Mexico, but you risk fakes, counterfeits, lower quality, or lower dose per ml. You also, of course, face the possibility that you’ll be stopped.
