Best Poppers Brand

This needs to be limited to formulations available in the states as what sells on other countries is different then what the FDA allows here. Tradditionally, Rush brand was considered the best not only for sex, but during the disco years. That's the one I've used since the late 70's when I was turned on to it. Recently, it doesn't seem to be anything like the original. I never got the horny, have to have sex feeling from the stuff, but more an intensive focus and emotional condensation to the moment along with a hot flush after the hit. No headaches or anything else. What's out there that's better? I never knew this feeling of getting so horny that I just had to bottom as some claim from Rush. Perhaps this is the effect from other formulations. Rush was a dance/club thing. I never really tried any of the others. Any input would greatly be appreciated.
