Depending on the number and character of their functional groups, steroid molecules may show diverse reactivities. Moreover, the reactivity of a functional group varies according to its location within the molecule (for example, esters are formed readily by 3-OH groups but only with difficulty by the 11β-OH group). An important property of steroids is polarity —., their solubility in oxygen-containing solvents (., water and alcohols ) rather than hydrocarbon solvents (., hexane and benzene ). Hydroxyl, ketonic, or ionizable (capable of dissociating to form electrically charged particles) groups in a steroid molecule increase its polarity to an extent that is strongly influenced by the spatial arrangement of the atoms within the molecule.

I know this is old but i had to reply.
As an example peak serum levels after a single injection of test enan occur between 48hrs and 72hrs.
This is the time that is used to get the average biological half lives of steroids, if the half life is taken from this point it is called the terminal half life, it's ascertained using a formula called pseudo equilibrium dynamics.
This is the formula that all medical scientists use to ascertain the half lives of steroids.
The half lives of the steroids in the link are wrong.
Testosterone enanthate for example has a half life (all half lives are variable) of days > days.
