Optimus Penis

What are all the supplements that are a must for making your penis consistently hornier and harder (without directly raising testosterone)?

I half expected this thread to be some obscene reference to Transformers.

Thanks Flash, I couldn’t place the reference and it was bugging me.

I hear alot about Horny Goat Weed. Bodybuilding.com has a whole supplement section dedicated to sexual health, you should check it out.

Thanks CristoDantes :)

Transformers in theaters July 2007!
