Testosterone enantate benzilic acid hydrazone

Testosterone enantate benzilic acid hydrazone (TEBH), or testosterone 17β-enantate 3-benzilic acid hydrazone, is a synthetic, injected androgen/anabolic steroid and an androgen ester – specifically, the C17β enantate (heptanoate) ester and C3 benzilic acid hydrazone of testosterone.[1][2] It was previously marketed in combination with estradiol benzoate and estradiol dienantate under the brand names Climacteron, Lactimex, and Lactostat.[2][3][4] Clinical studies have assessed this formulation.[5][6][7][8][9][10][11][2] TEBH was first described in the scientific literature in 1959.[12] It is a very long-lasting prodrug of testosterone when administered in oil via intramuscular injection.[13][14][15]
