Initially Iron Fist was released in Amyl Nitrite, with a formula that gradually increased in intensity overtime. Since then, Iron Fist have released Pentyl and n-Pentyl formulas which get to work a lot faster.

Like most things in life, people have their own preferences when it comes to the above. Generally speaking, people will tend to find amyl nitrite having a longer build up to a peak, while isopropyl and pentyl’s effects will hit more immediately but last a shorter length of time.

As soon as your poppers arrive please store them upright. Over time, the chemicals in a popper bottle can dissolve the sealant around the lid and cause a leak. 

We keep limited stock of our poppers to hand so that you’re always receiving fresh bottles. To ensure they stay fresh, we recommend keeping them refrigerated, or at the very least somewhere dark and not too warm.

Check out our blog post on how to store poppers for more information.

If poppers are properly stored, they should stay effective for a number of weeks. After this, they may begin to lose potency, but this will depend on the individual and the formula.
