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. 
Please understand Tren cycles of this nature are very dangerous, they are hard on your heart and blood pressure and if you desire to remain safe they are not something you will ever want to mess with; we have simply made you aware of what some do but this does not mean you should do it to. The reality is very simple, there is hardly a man out there no matter how far advanced that needs more than 100mg of Trenbolone every other day; we can however make an exception of making this dose daily the last 10-14 days before a bodybuilding competition for a hardening affect but thats it.
