250mg of primo seems like a waste of time to me, but to each their own I guees. I advocate low dose cycling for health reasons but primo is a pretty much weak compound. I think starting at 400mg would be a better approach and keeping your testosterone at trt script levels 100-200 weekly.
It is well within reason that AAS increases your BP, just monitor it. I cycle frequently so one day I went to the dr on cycle with elevated bp and got a script med for it just to be safe and I take that all the time now also with a built in but safe diuretic. Long term high blood pressure is a kidney killer, when people take gear alot of inexperience people which id say 90% are, neglect kidneys and just roll on. Dont do this.
Also, if you dont know whats going on its best to have bloods pulled immediately I believe which was already stated as well. Idk about you but when i crash my estrogen im stuck with a limp dick and a very bitchy attitude, something you don’t want happening probably dont even need one honestly but again blood work
