History:
Trestolone is a synthetic compound first synthesized by J. Babcock and G. Duncan of the Upjohn Company, reported in 1963.

Structure and Function:
Trestolone is a 19-nortestosterone derivative, differing by the addition of a 7a-methyl group. Unlike steroids like testosterone and DHT, trestolone shows no affinity for SHBG, leading to a short half-life. The 7a-methyl group causes steric hindrance to 5a-reduction, and conformational changes that lead to increased androgen receptor affinity.
