Shipping & Returns

Lost, Stolen, Damaged, Incorrect, or Missing Items

Delivered Packages

Peptira LLC is not responsible for packages that are marked as “Delivered” by the carrier and subsequently lost or stolen. This includes, but is not limited to, theft from porches, mailrooms, front desks, lockers, or other delivery locations.

Customers are responsible for:

• Ensuring a secure delivery location

• Monitoring tracking updates

• Retrieving packages promptly upon delivery

We strongly recommend using carrier hold options, signature-required delivery (when available), or secure delivery addresses if package theft is a concern.

Non-Delivery, Damage, or Fulfillment Errors

All shipping-related issues other than theft after delivery must be reported within seven (7) calendar days of the carrier’s delivery or attempted delivery date.
This timeframe is firm. Requests submitted outside of this window will be declined without exception.

For claims involving damage, missing items, or fulfillment errors, the following documentation is required in full:

• A complete unboxing video recorded from the moment the package is first opened

• Clear photos of the external packaging

• Clear photos of the contents of the package

• Clear photos of the packing slip included inside the package

• The tracking number

• A brief written description of the issue

Failure to provide all required documentation will result in the claim being denied.

If a claim is reviewed and verified as a Peptira LLC fulfillment or shipping error, the affected items will be reshipped at no additional cost. No cash refunds will be issued.

Cancellations, Returns & Refunds

All sales are final.

Orders cannot be canceled or modified once placed. Due to the sensitive nature of research materials and applicable regulations:

• Returns are not accepted

• Refunds are not issued for change of mind, user error, or refused delivery

• Chargebacks filed for delivered or stolen packages will be disputed with supporting documentation

Reshipments are considered only in cases of verified fulfillment errors or shipping damage that meet the documentation requirements outlined above.
