Simple Peptide or Sports Technology Labs?

On our stars Sports Technology Labs comes out ahead, 3.6 to 3.4. Sports Technology Labs lets you open its certificates before you order; Simple Peptide does not, and for a first order that gap matters more than any price. Only Sports Technology Labs lists the reference vial, so we cannot call the price question. Both take cards.
