Koi Peptides or Sports Technology Labs?

On our stars the two land level at 3.6. Both let you open a certificate before you spend anything, so paperwork will not separate them for most buyers. Only Sports Technology Labs lists the reference vial, so we cannot call the price question. Both take cards.
