GHK-CU Problem

[Berko74]

Hi guys,
Quingdao GHK-CU arrived today - after a month.
9 vials from 10 looks really weird: material looks pretty much like a dry bogey.
There is a picture about that with a Sigma Aaudley GHK-CU for comparision too.
Is this still usable? Or should I throw it in the trash?
What do you think?

I have these as well, and I don't think they were lyophilized properly. Mine look like cake shrinkage, which means there was residual moisture left after lyophilization. The only way to know if it's still good is to get it tested.
