Traditionally, Amsterdam Poppers were sold with an isopropyl formula, and many of their poppers still stick true to this. However, over the 30+ years since their inception, we’ve also seen Amsterdam release Amyl and Pentyl poppers. 

There’s no ‘best’ formula and different people have their own preferences. If unsure, the best way to work out what you’ll prefer is to try!

As a general rule, it is often said that amyl nitrite poppers will have a longer build up time to their peak and last longer. By contrast, it is often said that isopropyl and pentyl will take effect much faster, but equally last for a shorter amount of time. 

To ensure your Amsterdam poppers stay as fresh as long as possible, store them upright as soon as they arrive. While a few days in transit will be fine, the chemicals in poppers are corrosive and will eventually dissolve the sealant placed around the lid. This will also help avoid any leakages. 

To ensure we only send you fresh bottles, we keep limited stock ourselves. To keep them this way we also recommend keeping them refrigerated, or at the very least somewhere dark and not too warm. 

As long as your poppers are properly cared for and stored, they should stay potent for a number of weeks after first opening. Your poppers will eventually begin to lose strength, but this will depend on a number of factors including the formula, storage and bottle.
