It’s just residue from the lyopholization process.I just received my purchase, and I'm not sure if what appears on the sides of the Vial is normal, does it look like moisture, or is it just in my head?

It looks normal, although this vendor is not very reputable, they use fake COAs, so I'd recommend you send one vial for testingp
