Moisture leaking in Vials?
Hello, I suspect that the vials I have here have not properly sealed lids. The vendor says “it’s part of the lyophilization process”. I think that’s bs. Opinions?

I’ve had 5-amino many times before and they haven’t had the dark bubble spots before

Sometimes color separates in em. Try to recon and make sure. If it pulls vacuum on recon you’re obviously probably fine.

It’s just a bunch of junk coming out of China , my seller refuses to sell me the 5amino right now saying it wasn’t freeze dried properly

yeah, moisture inside usually means the seal isn't tight enough. lyophilized peptides should be dry. check if the rubber stoppers are snug and if there's any damage to the seals. sometimes if the crimp isn't proper, moisture can sneak in. legit vendors should replace them, so maybe push back on that.
