Effective Date: 07/07/2026

We want customers to have a clear and reliable ordering experience. Because Dynagen Peptides sells research materials, including products that may be temperature-sensitive or subject to chain-of-custody concerns, returns and refunds are limited as described below.

1. Order Cancellations

Orders may be cancelled before fulfillment begins. Once an order has been packed, dispatched, or transferred to a carrier, cancellation may no longer be available.

2. Returns

Due to product integrity, temperature control, contamination risk, and chain-of-custody requirements, we generally do not accept returns of research products once shipped.

3. Damaged or Incorrect Items

If an item arrives damaged, incorrect, or missing, contact us within 48 hours of delivery at [support email]. Include your order number, photos of the package and product, and a description of the issue. We may offer a replacement, store credit, or refund at our discretion after review.

4. Delivery Issues

If tracking shows delivery but the package is not received, contact the carrier and Dynagen Peptides promptly. We will review carrier tracking and shipping details, but we are not responsible for packages lost due to incorrect addresses, unattended delivery locations, theft after delivery, or customer failure to retrieve the package.

5. Temperature-Sensitive Products

Customers are responsible for retrieving packages promptly upon delivery and following product storage instructions. Refunds or replacements may be denied if delivery was completed and the package was not retrieved in a timely manner.

6. Chargebacks

Customers agree to contact Dynagen Peptides first to resolve order issues before filing a payment dispute or chargeback. Fraudulent or bad-faith chargebacks may result in account restriction and collection of amounts owed where permitted by law.
