There is something that works for most people who try this stuff. You can fool some people most of the time and not fool a lot of people not often enough.
The actual science behind this stuff is valid enough - we all produce testostrone after all and androgens are available as internal supplements (androgens are used by the medical profession as drugs as injections to correct some sex drive problems)
Androrolgy labs are sperm banks in other words so its big business (just some medical technincal info there)
The beatuy of this forum is that on top of the phero data there are links and advice for improving self confidence and info on commication and links to sites like askmen.com and fastseduciton.com etc.
