Alpha Labs Peptides or Core 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. Alpha Labs Peptides is the cheaper of the two on the reference vial, $20.99 against $52 at Core Peptides. Core Peptides takes cards and Alpha Labs Peptides does not, which decides it for anyone who wants chargeback rights.
