I have also heard that the gene for male pattern baldness is carried on the X chromosome making it a sex-linked trait. I have not checked up on this, but I think it is accurate. This means looking at your mom's dad can give you some clue as to whether or not you are susceptible, but even this is not set in stone. However, it's my OPINION that unless you are very prone to hairloss, a total of 175mgs/week of dbol shouldn't really cause any problems.
