PQRS Refund & Replacement Policy
Effective Date: January 1, 2026
At Premier Quality Research Solutions (PQRS), we stand behind the quality specifications published for our research materials. For products represented as meeting our 99% purity standard, PQRS guarantees a minimum purity of 99%, subject to the terms below.
1. The PQRS Guarantee
99% Purity Standard
Core research peptides and compounds specifically represented by PQRS as meeting our 99% purity standard are guaranteed to meet or exceed 99% purity based on applicable analytical testing.
Disclosed Exceptions
Certain complex molecular sequences or other products may be offered with a disclosed specification below 99%, including products identified in our catalog as having a 95%–98% purity range. Those products are guaranteed only to meet the purity specification disclosed for that product at the time of purchase.
Lot-Specific Results
Where lot-specific analytical documentation is provided, the specifications and results shown for that lot apply.
2. How to Submit a Quality Claim
If independent laboratory testing indicates that a product does not meet the applicable purity specification, please submit a quality claim within 45 days of the original purchase date.
Please provide:
- Your PQRS order number.
- The product name and, where available, lot or batch information.
- A complete report from an independent third-party laboratory using an appropriate analytical method, such as HPLC and/or mass spectrometry.
Send the documentation to PQRS Support for review. PQRS may compare the submitted results with available manufacturer, supplier, or retained analytical records for the applicable batch.
3. Resolution Options
If PQRS verifies that a product does not meet the applicable published purity specification, you may choose one of the following:
Product Replacement
PQRS will provide a replacement product from a verified batch at no additional product cost.
Full Refund
PQRS will issue a refund of the purchase price paid for the affected product to the original payment method.
4. Shipping and Transit Issues
Damaged or Compromised Products
If a product arrives damaged or visibly compromised, please contact PQRS within 72 hours of delivery and provide photographs showing the condition of the shipment and product. Verified transit-damage claims are eligible for replacement.
Domestic Shipping
PQRS ships orders from its Texas facility and uses packaging procedures intended to protect products during domestic transit.
5. Limitations
Quality claims under this policy must be submitted within 45 days of the original purchase date unless otherwise required by applicable law.
This guarantee applies solely to the identity and applicable purity specification of the research material.
This guarantee does not apply to, and does not guarantee, the outcome of any research protocol, experimental procedure, analytical method, or other use of the product. Research outcomes may depend on handling, storage, preparation, methodology, equipment, environmental conditions, and other factors outside the control of PQRS.
This policy does not limit any rights or remedies that cannot legally be limited under applicable law.
