After that, mixing slow/fast burn esthers becomes problematic, as now you must manage to the shortest burning esther to maintain that stable blood serum level. Which means, if prop is one of the esthers, you must inject at least every other day. defeats the purpose of having slow burn esthers in there.
There is one advantage if you accept to injecting eod. and that being, with the slow burning esthers, blood serum levels are stable over the course of a day, but not over a week (again, think e and c). with the fast burning esthers, blood serum levels are stable over the period of a week, but not over a period of a day. So by injecting sust eod, you get the best of both.
assume:
prop is injected eod
e and c are injected 1xweek
note:
you can accomplish the same thing by injecting e or c eod too, and at a substantially reduced cost
hope this helps!
