some decent info here, lots of misinformation...
since you asked for the cons...
winstrol may:
thin out your hair
cause a bit of dryness in the joints
if taken orally in high dosages for too long may affect the liver
dbol may:
cause a decent amount of water retention (aka moonface)
at times painful lower back pumps
again same potential liver issues...
it won't make you grow tumors out your nose, and is certainly not a magic pill... he'll still need the proper diet and training.... as far as will you be able to reach the same naturally.... well that depends if you have the discipline to eat and train properly... (most likely not)....
here is some detailed info for you...
Dbol:

Winstrol:

some helpful advice to your friend would be make sure he runs some sort of testoserone with whatever oral he's running... it'll mitigate the side effects...
but anyways those are the basic downsides.... at the end of the day its his choice, but atleast you can give him some proper information....
