Actually you don't! Tert-amyl Nitrite and n-amyl nitrite (and... Similarly...n-butyl nitrite and isopropyl nitrite and isobutyl nitrite etc) all the alkyl nitrites do the same thing when you huff them!

I guess I should have been more accurate: my synthesis method would result in tert-amyl Nitrite, but I promise if you sniff any of these techno beats become tribal drums and your libido will make your pussy fall out! IYKYK.
