H-drol is a good beginner PH compound....low sides/good gains are reported.
Most run it at 50mgs. for a few weeks and then ramp it up to 75 for the last couple.
I personally don't feel it would be bad on hair loss(like P-plex). Run at least 5 wks..
Its(h-drol) a good recomp dry PH
Generally a serm is not needed...I would say reversitol,Lean extreme would be a bare minimum PCT(4 wks.)
Keep researching and good luck
