Returns & Refund Policy

Last Updated: April 15, 2026

This Returns & Refund Policy (“Refund Policy”) describes our position on returns, refunds, replacements, and the limited circumstances in which we may offer remedies for products purchased from Phase 1 Peptides LLC (“Phase 1 Peptides,” “we,” “us,” or “our”) through phase1-peptides.com. This Refund Policy is part of our Terms of Service. Capitalized terms not defined here have the meanings given in the Terms of Service.

1. All Sales Are Final

Because our products are research-grade materials with strict handling, storage, and chain-of-custody requirements, all sales are final. We do not accept returns, exchanges, or refunds for reasons including but not limited to:

  • Change of mind or no longer needing the product;
  • Ordering the wrong size, dose, or product;
  • Results not meeting research expectations;
  • Product opened or used;
  • Delay in processing, shipping, or carrier transit;
  • Shipping address errors provided by you;
  • Abandoned or refused shipments.

The only exceptions to this rule are set forth in Section 2 (Damaged, Defective, or Incorrect Items) and Section 3 (Shipping Issues) below.

2. Damaged, Defective, or Incorrect Items

If you receive an item that is (a) damaged in transit, (b) defective upon arrival, or (c) different from what you ordered, you may request review under this section.

2.1 Deadline to Report

You must notify us within forty-eight (48) hours of delivery (as shown by the carrier’s proof of delivery). Claims submitted after the 48-hour window will not be accepted.

2.2 Required Information

Submit your claim by email to support@phase1-peptides.com with:

  • Your order number;
  • A written description of the issue;
  • Clear, well-lit photographs of the packaging (including shipping label), the affected product(s), and any internal protective materials;
  • If applicable, the carrier’s delivery confirmation and any damage notes made by the carrier.

2.3 Our Review

We will investigate each claim in good faith. Our review may include requesting additional photos or information, contacting the carrier for delivery records, or inspecting a returned sample. We will respond within ten (10) business days with a determination.

2.4 Available Remedies

If your claim is approved, we may, at our sole discretion, offer one of the following remedies:

  • Replacement of the affected product(s) at no additional charge;
  • Store credit equal to the value of the affected product(s);
  • Refund of the affected product(s) to the original payment method.

Shipping charges are generally non-refundable. We will select the remedy we believe best suits the situation. Approval of one claim does not guarantee approval of any future claim.

2.5 Product Retention

You may be required to retain the affected product and packaging for a period of up to thirty (30) days to allow for carrier investigation or additional review. Do not discard or attempt to ship the product back without our written authorization.

3. Shipping Issues

3.1 Delivery Protection (Included Free)

Every order includes complimentary delivery protection covering packages that are lost, stolen, or damaged during transit, subject to our review and reasonable investigation. Delivery protection is not insurance and does not constitute a contract of insurance. We provide this protection at our sole discretion as a customer service benefit.

3.2 Lost or Stolen Packages

If your tracking shows “delivered” but you have not received the package, please first:

  • Check with members of your household, neighbors, property managers, or mailroom staff;
  • Wait 48 hours — packages are occasionally scanned as delivered before actual arrival;
  • Contact the carrier with the tracking number to open a trace.

If you still cannot locate the package after 48 hours, contact us at support@phase1-peptides.com within seven (7) days of the “delivered” scan so we can investigate.

3.3 Packages Marked Delivered to Wrong Address

If the carrier’s records indicate the package was delivered to a location different from the address you provided, we will investigate with the carrier. Phase 1 Peptides is not responsible for deliveries mis-routed due to address errors provided by you.

3.4 Carrier Delays and Delivery Estimates

Delivery time estimates are provided for convenience only and are not guarantees. Phase 1 Peptides is not responsible for delays caused by weather, carrier operational issues, regulatory holds, or incorrect shipping information.

4. Non-Refundable Fees and Charges

Where a refund is approved under this Refund Policy, the following amounts are generally non-refundable:

  • Shipping charges (except where we expressly agree otherwise);
  • Address-correction fees or carrier surcharges;
  • Payment processing fees, where applicable;
  • Taxes, where allowed by applicable law.

5. Cancellations and Modifications

Once an order is submitted and payment is captured, we begin fulfillment immediately. Accordingly, orders generally cannot be cancelled, modified, combined, or redirected after checkout. Please double-check your cart and shipping information before submitting your order.

If you wish to attempt a cancellation, email us at support@phase1-peptides.com immediately. We will try to accommodate your request if the order has not already been packed or shipped, but we make no guarantee that we will be able to do so.

6. Chargebacks and Payment Disputes

We expect customers to contact us first if there is any concern about an order. Filing a chargeback with your card issuer without first attempting to resolve the issue with us directly may be considered a breach of our Terms of Service. We reserve the right to:

  • Suspend or terminate your account;
  • Decline future orders;
  • Dispute improper chargebacks with documentation including order records, shipping confirmations, and customer communications;
  • Refer fraudulent chargebacks to law enforcement and collection agencies.

If you believe a charge is incorrect, please email support@phase1-peptides.com so we can review and resolve the matter promptly.

7. Refused or Returned Shipments

If you refuse delivery of a package or a package is returned to us because the address was incorrect or the delivery was not accepted, we are not obligated to refund or re-ship the order. If we choose to refund, we will deduct the original shipping cost and any return-shipping charges from the refund.

8. Store Credit

Store credit, where issued, is non-transferable, has no cash value, and may not be redeemed for cash. Store credit expires twelve (12) months after issuance unless otherwise stated at the time of issuance.

9. Discretionary Nature

The review and issuance of any remedy under this Refund Policy is at our sole discretion. We reserve the right to deny claims that do not meet the requirements set forth here or that we determine in good faith to be fraudulent, duplicative, or abusive.

10. Changes to This Policy

We may update this Refund Policy from time to time. When we do, we will post the updated Policy on this page and update the “Last Updated” date. The Refund Policy in effect at the time of your purchase governs that purchase.
