Why This Policy?

MannKind Labs specializes in research-grade peptides and premium wellness products that require:

• Strict Cold Chain Management: Our products must maintain specific temperature controls from storage through delivery.
• Single-Use Sterility: Once products leave our facility, we cannot verify storage conditions or guarantee product integrity if returned.
• Quality Assurance: We cannot resell products once they have left our controlled environment.
• Regulatory Compliance: As research peptides, these products must meet stringent handling and storage requirements.

Before You Order

To ensure you're making an informed purchase, we strongly encourage you to:

• Review all product descriptions, ingredients, and usage instructions carefully
• Verify the product variant, quantity, and concentration before adding to cart
• Confirm your shipping address is correct before checkout
• Contact our support team if you have any questions about product selection
• Review our product disclaimers regarding research use and FDA compliance

Damaged or Defective Products

While all sales are final, we stand behind the quality of our products. If you receive a product that is:

• Damaged during shipping (broken seals, leaking, crushed packaging)
• Defective or contaminated
• Different from what you ordered (wrong product sent)

Please contact our support team immediately at info@mannkindlabs.com within 48 hours of delivery. Include:

• Your order number
• Clear photos of the damaged/defective product and packaging
• Description of the issue

We will review each case individually and may, at our sole discretion, provide a replacement or store credit for verified product defects or shipping damage.

Shipping Errors

If we ship you the wrong product or an incorrect quantity, please contact us within 48 hours of delivery. We will arrange for return shipping at our expense and send you the correct product at no additional charge.

Order Cancellations

You may cancel your order only before it ships. Once your order has been fulfilled and shipped, it cannot be cancelled. To request a cancellation, contact us immediately at info@mannkindlabs.com.

Warranty and Product Quality

While we do not accept returns or offer refunds under normal circumstances, we stand behind the quality of our research-grade peptides:

• Third-Party Testing: All peptides undergo independent third-party testing for purity and composition
• Certificates of Analysis (COAs): Available upon request for products showing testing results
• Quality Assurance: Products are manufactured in FDA-registered facilities following cGMP standards
• Proper Storage: Cold chain products are shipped with appropriate cooling measures to maintain integrity
