Is this saline water suitable for Semax and Selank nasal spray?

Hey everyone.
About to kick off semax and selank in the coming days, grabbed some saline solution to mix them up into a nasal spray form. Slightly paranoid the wrong bottle ended up in the cart though. Can anyone confirm whether this actually does the job? And if not, what should be sourced instead here in the uk?

Plain saline should be fine for mixing those two, I've done the intranasal route with semax before and it worked well, just make sure you're not accidentally grabbing one with added preservatives or medication in it since some saline bottles at the pharmacy aren't just saline.

Check the molecular weight if you're unsure what you actually bought, semax and the amidated version aren't identical and it matters more for absorption through the nasal route than it would injecting.

I made mine with saline plus the peptide and did a few squirts per dose, worked out fine for me. One thing I'd do differently looking back is splitting the vial so part goes nasal and part stays available for subq, gives you a way to compare if the spray version feels weaker.

Just make sure you're aiming it right, semax and selank need to go further back toward the nasopharynx to actually absorb, not just a quick sniff at the front of the nostril. Wrong technique will waste a lot of it no matter how good your saline mix is.
