SprayPack Kit: Instructions and Safety Guidance for Preparing Custom-Dosed Nasal Sprays

The SprayPack Kit is presented as a way to prepare custom-mixed nasal sprays from water-soluble powders, pills, or crystalline substances, with dosing controlled through a provided chart. The kit includes a nasal spray bottle, saline bullets, a funnel, a prism pick, and instructions. Users are told to weigh or measure the substance, dissolve it in preservative-free 0.9% saline, shake the bottle thoroughly, and administer sprays carefully. The guidance emphasizes avoiding the eyes, cleaning the device between uses, consulting a medical professional, and observing saline expiration dates. Mixtures are recommended for use within one week, although potency and contamination risks may vary. Refrigeration is described as potentially slowing bacterial growth but not proven. The product states that it is not intended for illicit substance use.
