Here is another one of those cartoons that requires some explanation.
The two molecules in this cartoon are Sildenafil (right - more commonly known as Viagra) and Cyproterone (left - also known as Cyprostat). Unlike Sildenafil, you will never find advertising campaigns on TV, or spam in your inbox selling Cyproteron. Aside from a few clinical uses, this molecule is possibly best known for its ability to suppress sex drive. In some parts of the world it is even used in the "chemical castration" of repeat sex offenders.
So, how long would it last if these two molecules got together? I'm not sure - but there is NO WAY viagra would settle for platonic!
"- Of course I like you, you're great! But, at the end of the day, we are just not sexually compatible."
