(1,2,6,7-3H)-Testosterone is a radiolabeled form of the corresponding steroid hormone. It can be used to study testosterone metabolism and androgen receptor binding in tissues.

Testosterone succinate (Testosterone hemisuccinate) is a negatively charged derivative of Testosterone. It has being shown that Testosterone succinate induced relaxation of rat aorta, the effect was androgen structure specific and involved K+ channel activation. Testosterone succinate has being studied with respect to its antiviral activity.

Boldione, also known as androstadienedione or 1-dehydroandrostenedione, as well as 1,4-androstadiene-3,17-dione, is an important industrial precursor for various steroid hormones. Boldione is a direct precursor (prohormone) to the anabolic steroid boldenone (1,4-androstadiene-17beta-ol-3-one). It is advertised as a highly anabolic/androgenic compound promoting muscularity, enhancing strength and overall physical performance, and is available on the Internet and in health stores. Boldione was marketed as a prohormone “dietary supplement” for many years in the mid-2000’s, but it is truly a potent precursor (ie. converts in the body) to the anabolic steroid Boldenone. In 2005 the Anabolic Steroid Control Act of 2005 classified boldenone as a Schedule III controlled illegal steroid.
