Reconstitution for intranasal Semax/Selank — preservation concerns

Bac water is standard. The benzyl alcohol is there specifically to keep contamination down over weeks. Preservative-free saline is for single-use or very short turnaround.

Fridge storage regardless of diluent. Room-temp nasal sprays on a desk are a bad idea for anything peptide-based.

I reconstitute smaller batches (1mg of peptide at a time into ~3mL) so I burn through them in 2-3 weeks. Fewer preservation headaches than sitting on a full 5mg vial diluted.

First time reconstituting anything intranasal — this helped, thanks.
