here is what Big cat on bb.com said about hairloss and m1t and superdrol
"Both compounds are already 5-alpha-reduced (derived from DHT) and thus do not interact with the 5alpha-reductase enzyme. Neither compound converts to a more potent androgen.
Superdrol is basically DHT with 2 added methyl groups and M1T is DHT with an added 1,2 double bond."
and then to clarify things a bit he followed up with:
"Both compounds are quite androgenic of themselves, so there is a certain risk for those ailments. However unless you have reason to suspect you will suffer them, I wouldn't worry too much, their prevalence isn't as high as you think. Things are often exaggerated for various reasons, and of course surfing message boards, people tend to post more when they have a problem."
basically the hair loss effects are minimal from superdrol or m1t, unless your family is already pre-disposed of this you shouldn't have to worry,
