Core Peptides or Evolve Peptides?

On our stars Core Peptides comes out ahead, 3.8 to 3.4. Both let you open a certificate before you spend anything, so paperwork will not separate them for most buyers. Evolve Peptides is the cheaper of the two on the reference vial, $39.90 against $52 at Core Peptides. Core Peptides takes cards and Evolve Peptides does not, which decides it for anyone who wants chargeback rights.
