Tren is an extremely androgenic hormone, and as a result well known for promoting androgenic side effects. Hair loss and acne in men who are predisposed are both possible. Body hair growth is also possible. If you are not genetically predisposed no amount of Tren on earth with cause these issues. The androgenic side effects of Tren are truly based on genetic response. When it comes to hair loss, if you are predisposed to male pattern baldness, meaning at some point you’re going to lose your hair regardless of steroid use , Tren is one of the fastest ways to ensure you lose your hair a little sooner.
Virilization is a serious androgenic side effect of Tren. It is very difficult for a woman to use Tren without some level of virilization and makes it a steroid that’s almost never recommended for female use.
Important Note: The 5-alpha reductase enzyme does not metabolize the Trenbolone hormone. This means 5-alpha reductase inhibitors like Finasteride will not affect the androgenicity of the hormone.
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.
