Returns and Refunds Policy

No Returns Policy
Due to the specialized nature of research peptides, regulatory requirements, and product integrity considerations:
NO RETURNS ARE ACCEPTED
NO EXCHANGES ARE PERMITTED NO REFUNDS WILL BE PROVIDED
This policy applies to all products sold by PeptideSupply.us without exception.
Why No Returns?
