Welcome to LOOP Labs.

LOOP Labs provides research-use-only peptides that are manufactured in the USA, third-party tested, and verified for high purity. The following information is provided to clarify our policies and practices. By purchasing from Loop Labs, you agree to use all products solely for lawful research purposes.

Disclaimers

All products sold by Loop Bio Labs, LLC are for research and educational use only. They are not intended for human or veterinary consumption, nor are they for clinical, diagnostic, therapeutic, or cosmetic purposes. These compounds have not been evaluated or approved by the FDA and should not be used to treat, cure, or prevent any disease or health condition. If we suspect that products are being used for personal use, and you are not a research institution, we reserve the right to cancel your order and block you from placing future orders.

General Information

Do you provide any information on dosing or reconstitution?
No. Loop Labs sells research-use-only peptides to qualified researchers. Because these products are not FDA-approved for human use, we cannot provide guidance on dosing, reconstitution, administration, or storage.

If you require end-user protocols, our products may not be appropriate; repeated requests for such guidance may result in order restrictions under our terms.

Where are you located?
Our headquarters and shipping operations are based in Dallas, Texas.

Do you have customer support?
Yes! While we don’t have a call center, our team is available via email to help with questions about your order or subscription. The best way to reach us is through our “Contact Us” page. We typically respond within 1-2 business days.

What are research peptides?
Research peptides are short chains of amino acids used in laboratory settings to investigate potential biological effects. These peptides may be studied in the context of cellular signaling, growth regulation, or metabolism—but they are not approved for clinical use.

What is the quality of your research peptides?
Each batch undergoes third-party testing to verify identity and purity (99%+).

Are Certificates of Analysis (COAs) available?
Yes. COAs are available upon request and are intended solely for informational and verification purposes. COAs do not imply approval or endorsement of safety, efficacy, or legal use.

Do I need a prescription to purchase from Loop Labs?
No. Our products are not drugs or dietary supplements and do not require a prescription.

Are Loop Labs products safe?
LOOP Labs does not make any claims about the safety, efficacy, or appropriate application of its research peptides. LOOP Labs disclaims all liability related to the use or misuse of any product.

Can I track my order?
Absolutely. You’ll receive an email with tracking information as soon as your order is shipped.

What if my order fails to deliver?
If an order is returned due to failed delivery attempts (e.g. nobody available to receive it), it won’t be resent automatically. You can request reshipment within 5 days by emailing shipping@loopbiolabs.com. A reshipment fee may apply.

What should I know about receiving my order?
Peptides should not be left outside or unrefrigerated for extended periods of time. We strongly recommend monitoring your tracking information to ensure you can promptly receive your shipment. If you will be unavailable at the time of delivery or prefer signature confirmation, you must request this directly through the shipping carrier. LOOP Labs is not responsible for packages once they have been handed off to the carrier, including loss, theft, or damage due to exposure. It is your responsibility to arrange secure delivery and proper storage upon receipt.

Can I update my shipping address after placing an order?
Unfortunately, we cannot guarantee address changes after checkout. Orders sent to incorrect addresses are not eligible for replacement or refund.

Do you offer a delivery guarantee?
