Loti Labs vs Peptide Perfection

Peptide Perfection scores higher, 6.7 to 5.9 out of 10. Both let you open a certificate before you spend anything, so certificates will not separate them. Only Loti Labs lists the reference vial, so we cannot call the price question. Loti Labs takes cards and Peptide Perfection does not, which settles it if you want chargeback rights.
