Questions, answered.

Everything about our compounds, testing, shipping, payment and research-use policy.

01What exactly are research peptides?
Research peptides are short chains of amino acids synthesized for use in laboratory and scientific study. They are supplied as sterile lyophilized (freeze-dried) powders and are intended strictly for in-vitro research and experimental applications, never for human or animal consumption.
02How are your compounds supplied?
Each compound is supplied as a sterile lyophilized powder in a sealed vial. Every product page lists molecular weight, composition and recommended storage so you know exactly what you are ordering. All products are sold strictly for laboratory research use.
03How are lots tested?
Lots are sent to Freedom Diagnostics, an independent laboratory, for purity and net-content analysis. Published results are on the verification page with links to the lab-hosted PDFs. Documentation for other lots is available on request.
04How should peptides be stored?
Lyophilized peptides are most stable stored at −20 °C, protected from light and moisture. Once reconstituted, keep them refrigerated and use them within the timeframe appropriate to the compound. Each product page lists storage conditions.
05How fast do orders ship?
In-stock orders dispatch within 24 hours on business days once payment is matched. Shipments use discreet, temperature-conscious packaging, and tracking is provided on every order.
06Is shipping discreet and secure?
Yes. Packaging is plain and unbranded, and order data is handled with privacy-first practices. Payments are matched to an order number before release.
07How do I pay?
Checkout gives you an order number. Pay the exact total with Venmo or PayPal and reference that number, or submit the order for review and receive emailed payment instructions. Card processing is not live yet.
08Who can purchase from Limitless Peptides?
Products are sold exclusively to qualified researchers, laboratories and institutions for legitimate research purposes. By ordering, you confirm you are purchasing for research use only and will handle all compounds in accordance with applicable laws and safety practices.
09Can these be used for human consumption?
No. All compounds are for laboratory research use only. They are not drugs, supplements or foods, are not intended to diagnose, treat, cure or prevent any disease, and must not be consumed by humans or animals under any circumstances.
10What is your return policy?
Opened vials cannot be returned. If a product arrives damaged or is not as described, contact us within 7 days and we will arrange a replacement or refund. See the returns policy for details.
