Trying New Treatments

DH was recently complaining about some pains in his knee when we had to climb some stairs after doing a lot of walking around town. His friend advised that he try hgh supplements which are said to be effective for joint pains. I think he is willing to try any form of treatment for his knee. I am for trying new treatments as long as it is mainly natural rather than chemical. I am currently a little wary of the untested new drugs that have been flooding the market.
