Despite the fact that Masteron was officially created in 1959, it didn’t reach the prescription drug market until 10 years later under the trade and brand name known as Masteron. Thanks to a collaborative agreement Lilly Pharmaceuticals would market Drostanolone in the United States under the name Drolban and Syntex would handle the marketing of Masteron internationally. Masteron is not medically used for putting on muscle as with most steroids, thus making it a unique steroid from that point of view. The majority of information on Masteron focuses on its use in treating certain forms of breast cancer, which it does fairly well. Most of the information on Masteron available in medical journals and studies do not focus on weight or strength gain or even fat loss, for those reasons.
