Alpha Labs Peptides or Nexaph?

On our stars Alpha Labs Peptides comes out ahead, 3.4 to 3.2. Both let you open a certificate before you spend anything, so paperwork will not separate them for most buyers. Only Alpha Labs Peptides lists the reference vial, so we cannot call the price question. Nexaph takes cards and Alpha Labs Peptides does not, which decides it for anyone who wants chargeback rights.
