Never used Primo...so far I've yet to be convinced to use it...seems week to me and I'd rather use Masteron.Other then that, I'd go 50mg ed on the winny your tren looks fine
but will you stack primo too !!?
i think test prop eod 100 mg will be fine , becouse a use tren acetat already...
Prop eod will be fine, ed is just my preference, but how does you using tren-a have any bearing on this?
