1. Research Use Only (Strict Limitation of Use)
All products sold by Premier Quality Research Solutions (PQRS) are intended strictly for laboratory research purposes only. By accessing this website or purchasing products, you represent and warrant that:
You will not distribute these materials for any purpose other than research and will comply with all local, state, and federal laws regarding the handling of research chemicals.

These compounds are not intended for human consumption, medical use, or veterinary use.
2. 99% Purity Guarantee & Independent Verification
PQRS stands behind the integrity of its core catalog with a 99% Purity Guarantee. To maintain a valid claim under this guarantee:
- Evidence Required: Any claim that a compound falls below guaranteed purity must be supported by a comprehensive, independent third-party laboratory report (e.g., HPLC/MS).
- Complexity Exception: Certain complex sequences are explicitly excluded from the 99% threshold if they are identified in the catalog as naturally stabilizing within the 95%–98% range.
- Sole Remedy: Our accountability is limited to a full replacement of the product or a refund of the purchase price.
3. Limitation of Liability
PQRS shall not be held liable for any damages, whether direct, indirect, or consequential, resulting from the use or misuse of its products. Under no circumstances shall PQRS’s liability exceed the actual purchase price of the specific material in question. The buyer assumes all risk for the results obtained from the use of the materials.
4. Texas-Based Fulfillment & Shipping
As a Texas-based supplier, we ship exclusively within the United States to maintain quality control.
Delivery Responsibility: PQRS is not responsible for delays caused by carrier service interruptions or incorrect shipping information provided by the buyer.
Transfer of Risk: Risk of loss and title for all products pass to the buyer once the package is handed to the shipping carrier at our facility.
5. Right to Refuse Service
PQRS reserves the right to refuse service, cancel orders, or terminate accounts at its sole discretion. We will immediately cancel any order if we have reason to believe the products are intended for non-research purposes or human consumption.
