BioLongevity Labs or Core Peptides?

On our stars Core Peptides comes out ahead, 3.8 to 3.5. 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. Both take cards.
