Filter when making a nasal spray?

[Rowurboat]

I'm relatively a noob and am just starting to get in filtering. I'm in the process of mixing some selank and semax nasal sprays with the help of @randy 's youtube vids, and noticed he didnt filter them.

Just wanted to get some clarification on why vs why not? Is there anything different about the peps being administered intranasal in regards to filtering?

Your rats nose is exposed to bacteria and mold daily. Its not an issue

Makes sense. Thanks for the clarification!

Not to hijack this post but I am in the process of doing the same. What do you recommend or do I need to sterilize the nasal sprayer? I don't see any being sold that are pre-sterilized. Thanks

@ricoadams i fill with 70% isopropyl alcohol, run the alcohol through the atomizer, let sit 10 minutes, then rinse with distilled water being sure to purge the alcohol from the atomizer with the distilled water.

@MyB Thank you for the suggestion. I'll do that.

I would say it depends on what bacteria is in the spray. And we really never know that. A filter is pennies worth of protection. As always everyone's level of perceived "safety" is different with this stuff. Know the risks and make your own decisions off the info you have.
