Core Peptides or Verified Peptides?

On our stars Core Peptides comes out ahead, 3.8 to 3.2. Both let you open a certificate before you spend anything, so paperwork will not separate them for most buyers. Only Core Peptides lists the reference vial, so we cannot call the price question. Core Peptides takes cards and Verified Peptides does not, which decides it for anyone who wants chargeback rights.
