I received a batch that was less powerful than I have had in the past from other sources. I contacted RIVN and they were cordial and caring. They replaced the vial free of charge. Thank you RIVN!!
Response from Rivn PeptidesAug 16, 2026
Hi Joe, thanks for the honest feedback. Every batch we produce is third-party lab tested for purity and quantity, consistently 99%+, so this is unusual. We’d like to make it right — please reach out to our support team with your order number and we’ll take a look.
