Limitless Biotech or Sports Technology Labs?

On our stars Sports Technology Labs comes out ahead, 3.6 to 3.1. 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. Sports Technology Labs takes cards and Limitless Biotech does not, which decides it for anyone who wants chargeback rights.
