Refund & Return Policy

Due to the sensitive nature of research chemicals and peptides, all sales are final.

We cannot accept returns or exchanges for any product once it has shipped.

This policy helps maintain product authenticity, safety, and purity for all customers.

For safety and regulatory reasons, the following items cannot be returned under any circumstances:

• Peptides and research chemicals
• Opened or unopened vials
• Reconstituted products
• Consumable laboratory materials
• Discounted, clearance, or promotional items
• Digital or downloadable content
• Merchandise

If you receive an incorrect product or an item is missing from your order, please notify us within 48 hours of delivery so we can review and resolve the issue.

Email us at info@sierrapacificpeptides.com with the following:

• Order number

We will promptly investigate and provide next steps.

If your package arrives damaged, please contact us within 48 hours of delivery.

Provide the following details to help us process your claim:

If the carrier marks your package as “Delivered” but you did not receive it:

• Contact the shipping carrier (USPS or FedEx) immediately to open a delivery inquiry or claim.
• Check with neighbors or your local postal carrier.

Sierra Pacific Peptides is not responsible for packages that are lost or stolen after carrier confirmation of delivery.
