De Martindale geeft volgende informatie:
“Testosterone may be used as a subcutaneous implant in a dose of 100 to 600 mg; plasma concentrations of testosterone are usually maintained
within the physiological range for 4 to 5 months with a dose of 600 mg. It may also be given by transdermal delivery systems. Patches are applied to the back, abdomen, thighs or upper arms to supply 2.5 to 7.5 mg daily. A scrotal patch containing 10 or 15 mg of testosterone and supplying about 4 or 6 mg of testosterone in 24 hours has been used, but is no longer widely available. Hydroalcoholic gels containing 1 or 2% testosterone are also used; they are applied daily to the shoulders and upper arms, abdomen, or thighs, depending on the preparation. About 10% of the applied dose is absorbed across the skin to provide a systemic dose of testosterone 5 to 10 mg. A sustained-release adhesive buccal system that contains testosterone 30 mg is applied twice daily; by this route the systemic dose is about 3 mg. Testosterone has also been given by intramuscular injection in a dose of up to 50 mg two or three times weekly, but testosterone esters are generally preferred by this route.”
