If there is hairloss in any side of your family you will experience hairloss if you take Steroids and prohormones are even worst I have friends that have used them, some of them don't lose hair at all and others start losing right away it is all genetics. My advice to you would be to NOT use any prohormones, try to get real gear, if you fear hair loss I would reccomend taking EQ alone or maybe anavar those are the only ''safe'' steroids when it comes to MPB. If you take Test and are predisposed to MPB you will suffer hair loss.
Personally I have not used anything and I am losing my hair anyways. damnnnn life sucks sometimes...

yeah don't touch prohormones they will give you way more side effects than real anabolics
