Questions we are asked about authenticity check

Does Vape Sourcing e-liquid need any accessory to be usable on day one?

In most cases no, it is usable straight away once charged or filled. The two things worth adding at the point of sale are a spare coil or pod and, for removable-cell devices, a proper storage case.

How long does a unit of Vape Sourcing e-liquid last in normal use?

For a typical adult user the answer sits between 7 and 12 days, depending on draw length and power setting. Heavy users will be at the short end of that range, which is worth knowing when you plan reorder volumes.

What strength should a retailer stock first for Vape Sourcing e-liquid?

Start with the middle strength in the range and add one step either side once you see what sells. Shops that open with a single strength almost always have to reorder within a fortnight, and the second order is usually the one that reveals the real demand curve.

How should Vape Sourcing e-liquid be stored to protect shelf life?

Cool, dark and sealed. Heat and direct sunlight degrade both nicotine and flavour well before the printed date, and a shop window is the worst place in the building to keep stock for any length of time.
