Our eLiquids are hand prepared in beautiful Southern California by proven biotechnologists to our exact recipe, using specialized laboratory equipment and proper technique. Unlike any nicotine liquid manufacturer on the market, we publish chemical data on our eLiquid for the public to see. We run each lot of nicotine through HPLC or LCMS (laboratory techniques to analyze an unknown for chemical content) to ensure only the desired chemical ingredients are present, no unwanted contaminants or degradation products. No beta-carbolines, no nitrosamines, never. We believe all “vapers” deserve the same validated chemistry and purity in an eLiquid that rivals the quality control specifications of an FDA-approved Nicotine Replacement Therapy (NRT) solution.

In addition, we never dilute our eliquids with water – Nude Nicotine eliquids are truly nude as they should be – only containing propylene glycol (PG), vegetable glycerin (VG), (nicotine), and flavoring. No hidden ingredients.
