All sales are final.

The Short Version

Because of the sensitive nature of research-grade peptides and the regulations governing them, every order placed with ProSource Labs LLC is considered final the moment it is submitted. The full terms below explain exactly what that means — and the narrow circumstances under which we will issue a reshipment.

Order Cancellations & Modifications

Orders cannot be cancelled, altered, or substituted once they have been placed. This includes changes to product, dosage, quantity, shipping address, or payment method. We recommend reviewing your cart carefully before checkout — and reaching out to support before placing your order if you have any questions.

Returns

Returns are not accepted under any circumstances. Once a parcel leaves our facility, the cold-chain custody is broken and the contents can no longer be re-introduced to our inventory.

Refunds

Refunds will not be issued for any of the following:

• Change of mind or buyer's remorse
• User error at checkout (wrong product, wrong dosage, wrong address)
• Refused, undeliverable, or unclaimed shipments
• Delays caused by the carrier once the parcel has left our facility

Chargebacks

Any chargeback filed against a delivered or carrier-confirmed shipment will be formally disputed using full supporting documentation — including order records, tracking history, proof of delivery, and customer correspondence. Fraudulent chargebacks may be referred to collections and reported to the appropriate networks.

Reshipments

A complimentary reshipment may be authorized — at the sole discretion of ProSource Labs LLC — in the following verified cases:

• Fulfillment error on our end (e.g. the wrong compound or dosage was shipped), confirmed against our outbound lot records.
• Shipping damage resulting in a broken vial or compromised packaging, documented with clear photographs taken within 48 hours of delivery.

Reshipment requests outside of these two categories will not be honored.

How to Submit a Claim

If you believe you qualify for a reshipment under the criteria above, reach out through our Contact form or email support@prosourcelabs.org within 48 hours of delivery. Please include:

• Your order number (e.g. PSL-XXXXXXXX)
• The email address used at checkout
• Clear, well-lit photographs of the issue (and packaging, if applicable)
• A brief description of the problem

The policies above exist to keep that promise fair to every researcher we serve, to prevent abuse of our reshipment goodwill, and to comply with the regulatory framework that governs research compounds. By placing an order with ProSource Labs LLC, you acknowledge that you have read these terms and agree to be bound by them in full.
