FAQs

What are research peptides?

Research peptides are short chains of amino acids studied for their effects on biological processes. At KÖLD, our peptides are intended strictly for in vitro and laboratory research purposes only. They are not for human consumption, diagnostic, or therapeutic use.

How should peptides be stored?

Peptides should be stored in a cool, dry place, ideally in a refrigerator at 2–8°C (35–46°F) for maximum stability. Once reconstituted, peptides should be used promptly and kept in the fridge unless stated otherwise. 🔬 You can find specific storage instructions on each product page.

Do you offer refunds or returns?

Due to the sensitive nature of research compounds, all sales are final. However, if your order arrives damaged or incorrect, our support team will make it right. Your research integrity is our top priority.

When will my order ship?

Orders are processed within 48 business hours after payment, Monday through Friday, excluding U.S. federal holidays. Once your order ships, tracking details are sent automatically by email.
