Superdrol is garbage. If you want an oral, your better off using any of the other "real" steroids and dump the pro-hormones. Dbol ,Var, Winstrol, Tbol all much better gains and much less harsh.
If your worried about hairloss then you can really on use:
Deca
Test but only with finasteride
Var
Tbol - possible hair loss with this but not sure.
EQ
Anything else will likely have a negative impact on your hairline.
