Synthetic Analogs
A number of synthetic analogs of testosterone have been developed with improved bioavailability and metabolic half life relative to testosterone. Many of these analogs have an alkyl group introduced at the C-17 position in order to prevent conjugation and hence improve oral bioavailability. These are the so-called “17-aa” (17-alkyl androgen) family of androgens such as fluoxymesterone and methyltestosterone.

Famous quotes containing the word synthetic:
“In every philosophical school, three thinkers succeed one another in the following way: the first produces out of himself the sap and seed, the second draws it out into threads and spins a synthetic web, and the third waits in this web for the sacrificial victims that are caught in itand tries to live off philosophy.”
—Friedrich Nietzsche (18441900)
