Why we built KTN Labs.
KTN Labs was founded with a simple goal: bring greater transparency and accountability to the research peptide space.
We entered this industry after seeing how difficult it was to find clear, accessible information about product testing and quality. KTN Labs was created to raise that standard.
Our priorities are simple: product quality, third-party testing, batch transparency, and dependable service.
What are KTN compounds intended for?
For in vitro laboratory research only by qualified professionals. Purchasers must be at least 21 years old. Products are not for human or animal consumption, administration, or diagnostic or therapeutic use. KTN Labs does not provide personal-use or dosing guidance. See our Terms & Conditions.
Where can I find a certificate of analysis?
Your batch-specific Certificate of Analysis (COA) will be provided after your order ships, because the batch is assigned during fulfillment. Match each report to the product, strength and lot you receive. If your order includes multiple lots, request a report for each lot. For help obtaining your COA, contact KTN Labs support with your order number, product and lot number. See COA information.
What should I look for on a COA?
Match the compound and lot number to your product. Review the laboratory name, report date, test methods and reported results. Reported results describe the tested sample and do not establish safety, effectiveness, or suitability for clinical use.
What is the difference between amount and vial format?
Amount is the listed quantity of compound per vial. Vial format identifies the container size or type, such as 6R or 10R. Vial format is not a concentration or dosing instruction.
What is the difference between a single compound and a blend?
Single-compound listings identify one compound. Blend listings identify the component combination where supplied. Review the exact listing and its documentation. Do not assume a component amount or composition that has not been confirmed.
Where can I review shipping options?
UPS 2-Day Flat Rate Shipping is $15 for U.S. orders, with free shipping on orders over $150 after discounts and before tax. The two-business-day transit estimate starts after shipment. Review your shipping total at checkout and see our Shipping Policy for details.
Does KTN Labs accept returns?
All sales are final, except for confirmed shipment errors or product problems and remedies required by applicable law. We do not accept change-of-mind returns. For a wrong product, strength, or quantity; a damaged, defective, missing, or undelivered item; or a failure to meet the specifications agreed for your order, contact KTN Labs support promptly. Keep your order details and packaging, and do not return materials without written authorization. See our Returns & Refunds Policy for the review and resolution process.
