Ultra Strong

Iron Fist Ultra Strong comes in a premium red aluminium bottle, available in two sizes: 10ml and 24ml. The 10ml uses Iron Fist's exclusive aluminium mould · a design developed and manufactured in-house at PWD Factory since the brand introduced the 10ml aluminium bottle to the market. Both formats feature the signature poppy-red label with silver Iron Fist branding and black cap.

Each bottle is sealed and dated for freshness. The aluminium construction protects the product from light and air exposure, maintaining quality throughout storage.

Ultra Strong is n-pentyl nitrite (formula CH₃(CH₂)₄–ONO), a straight-chain C5 alkyl nitrite. PWD Factory manufactures it using cold synthesis under inert atmosphere, followed by multi-stage rectification and desiccation to preserve molecular integrity.

This technical process ensures consistent purity and stability. n-Pentyl nitrite differs structurally from isoamyl (found in Original), though both contain five carbon atoms in different arrangements.
