Lyophilized powder vials

[jrod]

I’m trying to upload a picture of some peptide vials I have. Out of all the vials I bought, 3 of them the powder looks like it shrunk while the rest have normal size powder cakes in them.
Anyone know if that happens during the process or if it’s just less product in there.
I’ve cropped the picture several times but it says file too large.
