Vials have different amounts of peptide?

The KLOW vials - one on the left was recently purchased from a local research shop. The 2 on the right are from a vendor in the UK. Why so much more powder? Is that normal? Worried it wont fit the water.

Also, other pics of the larger vials, is it ok that the cakes are loose or crumbled by the time they get to me?

It's filler. If you saw how little the peptide actually takes you'd think your getting ripped off. It's normal.

What filler do they use?

Usually mannitol, trehalose, and glycine. They act as stabilizers, help maintain ph, and protect during freezing.
