Drinking topical minoxidil?

I have no idea if drinking topical minoxidil is safe or not but … If it were safe and effective ( that is a big if ), wouldn’t one bottle of Kirkland minoxidil last for 8 months?  You can save a lot of money this way, right? 

Minoxidil is a dangerous medication with potentially fatal consequences. Drinking an UNKNOWN dose of topical minoxidil may put you at risk, so why go there? You can be marginally wealthier when you’re dead.
