With h-drol most people will use a serm for pct.
I'm no doctor but I wouldn't run it without a serm for pct.
Most ph require a serm, even h drol and epi, which are considered mild.
Finaflex 1 andro and 1 alpha are 2 of the few who can be run with an otc pct. These coukd be better options if you can't get a serm.
Good luck bro, feel free to ask.
