A failed purity test should trigger a refund of the batch under a written threshold, not a negotiation. Notary Peptides refunds a batch in full when an accredited lab finds it under 98% purity or under 95% of the labelled fill, and pays the refund as money rather than store credit.
Either threshold missed, measured by an accredited lab on a vial from the delivered order: purity below 98% by HPLC, or the quantity in the vial below 95% of what the label states. Both numbers are written on the ordering page and apply to every order.
The lab report, which should quote the lot number of the vial tested, and the lab’s invoice. Notary Peptides answers a reported failure within 3 business days. The lab fee is reimbursed on any failed result regardless of order size, and on orders of 20 kits or more it is reimbursed whatever the result.
Refund. A store credit obliges the buyer to keep buying from a supplier whose batch just failed. A written guarantee that pays money back is the term to look for; wording such as “replacement or credit at our discretion” means the supplier decides after the fact.
A lot-coded supply makes this answerable: every kit sharing the failed lot number is covered by the same result. This is one of the practical reasons lot traceability matters to a reseller; see the traceability guide.
The product value of the batch is refunded in full; ask the supply team about shipping on the specific order.
The guarantee is written against an accredited lab’s result. If results conflict, raise it with the supply team; the answer comes within 3 business days.
Submit the report as soon as it is issued; the lot number on the report identifies the batch.
