Uhm what? Saline is a (often sterile) solution of water and (usually) 0.9% NaCl, aka sodium chloride.
Thanks for correcting those weird-ass random posts so I didn't have to, I heard interesting things about this compound and stumbled on this thread but these last few pages are kind of creepy.
I wanted to take the opportunity to say that despite embarrassing himself yaksha definitely does have something right in that metered nasal sprays are incredible for a variety of compounds. It sounds like he's using regular saline squirt bottles, which aren't a good idea because that means you're just wildly hosing unknown amounts of stuff into your nose, but I've taken to using these:

They're like two bucks each and allow for very precise, volumetric dosing down to 0.1ml. I actually tested mine before using them because the first compound I used them with was a fentanyl analog and I don't have much of a tolerance and obviously didn't want to screw around, and they're very close to 0.1ml per pump. This combined with nasal being a vastly superior ROA for nearly every substance, discretion and not needing to weigh out every dose means these metered pumps are the best way of dosing for any compound that you can get into solution, that doesn't have an active dose in the hundreds of milligrams. I use them for DOC, fent analogs, 5-meo-mipt and just about anything within reason... I'd use them for 4-fa, 5-mapb etc. too if I could find a solvent that could dissolve >200mg/ml of them

obviously don't use saline if it's a compound like 4-ho-mipt that is unstable in aqueous solutions.

I don't work for Snoot, these are just the cheapest, easiest to use bottles I've found. You're not limited to saline either - I'm hesitant to use something like 99% IPA in my nose, but to get something like b-f dissolved you need to use at least 40% ethanol and a little acid like vinegar, but with volumes this low it really doesn't burn too much.
Hope this helped someone!
edit: funny, I was surprised to see I had an account here because I didn't remember ever posting, guess I was right
