Amazon was never a good source, as discussed a number of times before.
Brand-name Hospira is sold here:

The FDA recently sent some letters to a few domestic peptide resellers that also sell Hospira. But many domestic resellers (not warehouses) sell Hospira (usually at a higher price than Injection Shop).
The BAC kits from China are to be avoided as much as the Amazon BAC. Both of those are arguably the number one reason for cloudy peptides, and they have no guarantee of preventing bacterial growth. Hospira is sold in bulk in cases, not kits.
