Ok... Trust me, if your moms dad and brothers are bald; chances are you will be too. You carry the gene from your mom's side, aas could speed the process up for sure.
That theory was disproved several years ago. The gene can be inherited from either side.
Anyways, if you're using Tren, then you probably aren't too worried about side effects. So just go with masteron, as you'll get more bang for your buck.
