I read that mixing Semax or Selank with saline water to make a nasal spray means it only lasts 7 to 10 days due to the different preservation between saline water and BAC water, after which it must be discarded. How can I avoid waste without necessarily increasing the dose?
I use 9.1mL Bacteriostatic with 8.9mL Saline. Maintains the minimum threshold of benzyl alcohol to remain a preservative and not too rough on the mucosa
