No one,you would have to find someone with 4 ad prop, no company was making it until I asked for it to be made. With the banmoving quick most manufactuerers wont want to start making special powders or ester unless you can order in 3kg amounts. 3kgs would last a LONG time. Its like 1,4add acetate, you wont see anyone with that either for the same reason.
I suppose you could do a 4 ad base(suspension) maybe 50mgs/ml with 4 ad cyp 200mg/ml, and if you can get either 4 oht cyp (50mgs/ml) or 4 oht deca 200mg/ml. 450mg/ml total. depending on which one you do.
