Refund Policy

At KZ Labs LLC (“KZ Labs”), we are committed to providing high-quality research materials. Due to the sensitive and controlled nature of our products, all sales are subject to the following policy.

1. All Sales Final

All products sold by KZ Labs are intended for laboratory research use only.

Due to the nature of research compounds, all sales are final once shipped, except as outlined below.

We do not accept returns of opened, used, or altered products under any circumstances.

2. Damaged or Incorrect Items

If you receive:

A damaged product
A leaking vial
An incorrect item
A missing item

You must notify us within 3 calendar days of delivery confirmation.

We stand by the purity of our products. However, due to the sensitive nature of peptides, replacements for reconstituted products are subject to strict quality control verification:

Reconstitution Media: Replacement requests are only honored if the researcher utilized KZ Labs or Hospira brand bacteriostatic water. Use of other solutions voids this guarantee.
Research Outcomes: We do not offer compensation or replacements based on subjective research results or experimental efficacy.
