NuScience Peptides or Paramount Peptides?

On our stars Paramount Peptides comes out ahead, 3.6 to 2.7. Both let you open a certificate before you spend anything, so paperwork will not separate them for most buyers. Neither shows card payments, so weigh how you would get your money back if an order went wrong.
