Power Pump and similar supplements (for my wife)

Probably this is not the right place to ask similar questions... anyway: my wife is training with weights and would like to use some supplements like Power Pump (http://powerhealthdirect.com/faqs.php) to help build some muscle. Is this Power Pump effective or kind of a hoax? Do you have any objective information about that?

Also, are there better alternatives?

I'm quite interested on the subject, since its possible implications for my wife's muscle development.

I searched the web and this Power Pump doesn't seem to be serious stuff.

Any advice, or links where to find some effective advice on supplements?

Creatine's tried and true ;)

Thanks for the reply.

I searched for information about creatine (which I already heard about) and it looks promising.

Anything more on the subject? Come on, may be of some help for other wifes/girlfriends, hopefully :-)
