Timeframe for switching to Mast E from Mast P

[Hisoka]

Currently running a cycle of
200mg Test E/wk (M/Thu)
140mg Tren A/EOD
70mg Mast P/EOD

Didn't notice before hand but looks like my supply sent me some Mast E instead of Mast P. Never ran the E before, doubt I'll have any issues, but if you were me, are you ordering more P or just rolling with the E. Not my first cycle, 3rd time running this stack, just honestly looking for opinions. And if you do just roll with it, how many weeks before running out of Mast P should I start incorporating the Mast E?

Thinking if I switch to E I'll probably just take it with my Test dose.
Anyway any opinions would be appreciated.

Thanks

I think Mast P is stupid. Just use E
