I've found this out since I've been working in a pharmacy. Just thought it was interesting what the actual medicinal indications of these drugs are. These are just some of the uses, not all.

Nolvadex (tomoxifen) is a breast cancer treatment medication, or more specifically, an antiestrogen, for women who have or who have a high risk of breast cancer. Arimidex is much the same.

Clomid (clomiphene) is a fertility drug used to help women who are having trouble getting pregnant.

Finaplix (trenbolone ) is used to promote weight gain and increased appetite in cows just prior to their slaughter.

Halotestin (fluoxymesterone) is another drug used to help treat breast cancer in women, but is a AA steroid , unlike arimidex and nolvadex.

Clenbuterol is a bronchodilator used to treat asthma in humans and in animals. It's illegal to possess in the US.
