testosterone enantate benzilic acid hydrazone 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. it was previously marketed in combination with estradiol benzoate and estradiol dienantate under the brand names climacteron, lactimex, and lactostat. clinical studies have assessed this formulation. tebh was first described in the scientific literature in 1959. it is a very long-lasting prodrug of testosterone when administered in oil via intramuscular injection. androgen replacement therapy formulations and dosages used in women routemedicationmajor brand namesformdosage oraltestosterone undecanoateandriol, jatenzocapsule40–80 mg 1x/1–2 days methyltestosteronemetandren, estratesttablet0.5–10 mg/day fluoxymesteronehalotestintablet1–2.5 mg 1x/1–2 days normethandroneaginecosidetablet5 mg/day tibolonelivialtablet1.25–2.5 mg/day prasterone (dhea)b–tablet10–100 mg/day sublingualmethyltestosteronemetandrentablet0.25 mg/day transdermaltestosteroneintrinsapatch150–300 μg/day androgelgel, cream1–10 mg/day vaginalprasterone (dhea)intrarosainsert6.5 mg/day injectiontestosterone propionateatestovironoil solution25 mg 1x/1–2 weeks testosterone enanthatedelatestryl, primodian depotoil solution25–100 mg 1x/4–6 weeks testosterone cypionatedepo-testosterone, depo-testadioloil solution25–100 mg 1x/4–6 weeks testosterone isobutyrateafemandren m, folivirinaqueous suspension25–50 mg 1x/4–6 weeks mixed testosterone estersclimacteronaoil solution150 mg 1x/4–8 weeks omnadren, sustanonoil solution50–100 mg 1x/4–6 weeks nandrolone decanoatedeca-durabolinoil solution25–50 mg 1x/6–12 weeks prasterone enanthateagynodian depotoil solution200 mg 1x/4–6 weeks implanttestosteronetestopelpellet50–100 mg 1x/3–6 months notes: premenopausal women produce about 230 ± 70 μg testosterone per day (6.4 ± 2.0 mg testosterone per 4 weeks), with a range of 130 to 330 μg per day (3.6–9.2 mg per 4 weeks). footnotes: a = mostly discontinued or unavailable. b = over-the-counter. sources: see template. testosterone enantatebenzilic acid hydrazoneclinical datatrade namesclimacteron, lactimex, lactostatother namestestosterone enantate benziloylhydrazone; testosterone 17β-enantate 3-benzilic acid hydrazone; tebh; tebah; tebahroutes ofadministrationintramuscular injectionidentifiers iupac name -10,13-dimethyl-1,2,6,7,8,9,11,12,14,15,16,17-dodecahydrocyclopentaphenanthren-17-yl] heptanoate cas number18625-33-7pubchem cid101982710drugbankdb13947chemspider21160607uniix8z8a2g2y4chemical and physical dataformulac40h52n2o4molar mass624.866 g·mol−13d model (jsmol)interactive image smiles ccccccc(=o)oc1cc21(cc32ccc4=c/c(=n\nc(=o)c(c5=cc=cc=c5)(c6=cc=cc=c6)o)/cc34c)c inchi inchi=1s/c40h52n2o4/c1-4-5-6-13-18-36(43)46-35-22-21-33-32-20-19-30-27-31(23-25-38(30,2)34(32)24-26-39(33,35)3)41-42-37(44)40(45,28-14-9-7-10-15-28)29-16-11-8-12-17-29/h7-12,14-17,27,32-35,45h,4-6,13,18-26h2,1-3h3,(h,42,44)/b41-31-/t32-,33-,34-,35?,38-,39-/m0/s1key:ptvxyacxdyznid-jknbftaxsa-n chemistry chemical synthesis of tebh has been described.
