Sterile water works for mixing Selank too, as an alternative to bacteriostatic water. There are step-by-step videos available online showing how. No need for a special sterile nasal spray container, but an amber glass one is good because it blocks light and preserves the peptide. With plain sterile water, store the spray in the fridge and finish it soon.
Anyone here reconstituted Selank for making a nasal spray? What solution did you use if you did, and where can sterile spray bottles be purchased?
