ahhh not a good idea. I am assuming you dont have too much PH experience or you would know not to do it. but if your heart is set on it heres a few options id consider.
SD to Epi bridge. very popular
Epi @30-50mg for 6wks, with pulsing 10mg SD 4x a wk pre WO.
30mg epi 4-5wks, 10mg SD 3wks stacked
both are toxic PH's that require liver support (meth's), cycle support.
how many cycles have you ran??
