Have you cracked open a vial yet? It usually has this odd “fishy” (for lack of a better word) smell, sometimes “vitamin-y.” It should have a smell is what I’m saying. Also, it’s thicker/more viscous like aminos tend to be.
I have some vials I got months ago from Raven’s server that were sourced from Nexaph, perfect. They were w/o b vitamins, I added my own from kits4less.
About a month or so ago I bought a couple of vials from a different person and as soon as I picked up the cherry-red vial I knew it was fake. Drew some out, no smell, super thin, and the red stained my hands.
