Androsol/Nandrosol....too young?

Hello, I am 19 years old and I am dying to try Androsol and Nandrosol to help me gain weight. Right now I am 5’9" and only weigh 160 pounds. My question is whether or not these supplements will negatively affect my hormone levels due to my younger age. Any advice would be greatly appreciated.

The matter isn’t studied, which is why
no positive recommendation can be made.
There is no known reason why effects would
be more adverse, but that doesn’t mean
they might not be.

I know that’s not much help, but that is
just how it is. Maybe someday science will
know more about it, but not anytime soon,
since it is not something anyone is studying
or is likely to want to study or even consider
ethical to study.
