One thing that you notice about trenbolone is that it is often a golden-brown / rust colour when in oil solution. If the hormone powder is refined to greater than % purity or so, then the colour of trenbolone in solution actually gives a very light golden colour, much like other testosterone products; however, refining the hormone to this level of purity is extremely difficult. This is why there is colour variation from batch to batch with different underground labs; something as small as % purity can affect the colour of the final product.
Being a progestin, trenbolone also has a dramatic effect on users’ natural testosterone production. Much in the same way that nandrolone does, trenbolone can suppress the natural production of testosterone for weeks after a user has ceased administering it. For this reason it is advisable that users use testosterone in conjunction with trenbolone if they wish to avoid sexual dysfunction, libido problems, or mental side effects associated with a lack of testosterone. Anecdotally many users have also reported that testicular atrophy is nearly always a problem when using trenbolone and that it is much more dramatic than with other compounds. Users may wish to administer human chorionic gonadotropin to help counteract this.
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.    In 1947, Dr. Bradbury Robinson , a physician and nutritionist practicing in St. Louis, Michigan , warned of the dangers of using the pesticide DDT in agriculture. DDT had been researched and manufactured in St. Louis by the Michigan Chemical Corporation , later purchased by Velsicol Chemical Corporation ,  and had become an important part of the local economy.  Citing research performed by Michigan State University  in 1946, Robinson, a past president of the local Conservation Club,  opined that:
