Key takeaways
Fluoxymesterone (Androxy) and testosterone enanthate are both medications used to treat low testosterone levels in males and metastatic breast cancer in females. However, they differ in several ways. Fluoxymesterone was available as an oral medication but has been discontinued in the United States. Testosterone enanthate, on the other hand, is given as an intramuscular injection, typically every 2 to 4 weeks. Common side effects of testosterone enanthate include acne and pain at the injection site. Additionally, testosterone enanthate has specific warnings about risks like blood clots, liver problems, and high calcium levels.
