PepLynx Biotech – Refund, Return & Cancellation Policy

Effective Date: October 23, 2025
Last Updated: November 21, 2025

This Refund, Return & Cancellation Policy (“Policy”) governs all purchases made from PepLynx Biotech LLC (“PepLynx,” “we,” “our,” “us”). This Policy forms part of the PepLynx Terms of Service. By placing an order, you acknowledge and agree to the terms below.

PepLynx supplies research-use-only peptides, chemicals, and laboratory materials. Due to strict quality control, safety regulations, chain-of-custody requirements, and the sensitive nature of our products, PepLynx maintains the following strict, industry-standard policies.

1. ALL SALES ARE FINAL (NO RETURNS)

Due to safety, sterility, contamination, and regulatory considerations, all sales are final.

PepLynx does not accept returns of any products — open or unopened — under any circumstances, except where explicitly stated in Section 4 (Damaged / Incorrect Items Review).

This policy is essential to maintain:

• Sterility and purity of research compounds
  
• cGMP-chain-of-custody integrity
  
• Regulatory compliance
  
• Prevention of tampering and contamination
  
• Laboratory safety standards
  

Once products leave our facility, they cannot legally or safely be returned, restocked, or reused.

2. PRODUCT NATURE – RESEARCH USE ONLY

All PepLynx products are sold strictly for laboratory research use only and are not for human or animal consumption, medical use, or diagnostic use.
Because these are sensitive, non-consumable research materials:

• Returns cannot be accepted
  
• Refunds are not provided
  
• Only verified issues may qualify for replacement/store credit
  
• PepLynx retains sole discretion over all claim decisions
  

3. ORDER CANCELLATIONS
