Steroid-like

Afimoxifene , [1] also known as 4-hydroxytamoxifen ( 4-OHT , 4-HT , OHTAM , others), is a selective estrogen receptor modulator (SERM) of the triphenylethylene group and the major active metabolite of tamoxifen . [2] [3] The drug is under development under the tentative trademark TamoGel as a topical gel for the treatment of hyperplasia of the breast . [2] [4] It has completed a phase II clinical trial for cyclical mastalgia , [5] but further studies are required before afimoxifene can be approved for this indication and marketed. [4]

The chemical formulas for steroids and steroid-like substances are complex and often very difficult to distinguish without in-depth laboratory analysis. Anabolic steroids—compounds “designed” to behave like testosterone—and supplemental testosterone products are classified as “controlled substances” and are regulated by the Drug Enforcement Administration. If a specific steroid is on the . Drug Enforcement Agency’s list of “controlled substances,” then it is easy to identify, but even when a substance is not listed, it may still violate federal and state laws. In addition, the substance may be banned by most athletic associations. Also, because steroid-like substances can produce positive drug test results similar to those of anabolic steroids, we advise using extreme caution when considering any “dietary supplement” product labeled as containing steroid-like ingredients—including prohormones, testosterone “boosters,” “designer steroids,” and anything else compared to or purported to behave as any known anabolic steroid. In addition, little is known about their safety.
