Once an order has been transferred to UPS, delivery timelines are outside of our direct control. Although most shipments arrive within 2–3 business days, delays may occur due to factors such as weather conditions, holidays, high-volume shipping periods, or weekends, during which packages may not be in active transit.
To maintain product integrity throughout shipping, all research materials are securely packaged in protective containers designed to shield vials from direct light exposure and temperature variation. Our lyophilized (freeze-dried) research peptides are inherently stable and capable of tolerating elevated temperatures for limited durations without compromising product quality.

Frequently Asked Questions
Answers to our most common questions.
What is this product used for?
This compound is intended exclusively for in vitro research purposes. It is not approved for human or animal consumption, cosmetic use, diagnostic testing, or any form of clinical application.
Are your products tested?
Yes. Each batch undergoes independent third-party testing conducted by a DEA-licensed U.S. laboratory. Testing verifies identity, purity, net content, and confirms the absence of endotoxins. Only batches that meet strict quality specifications are approved for research distribution.
What are endotoxins, and why are they tested?
Endotoxins are bacterial byproducts that can interfere with experimental accuracy, even at extremely low levels. Rebel Fitness tests every batch for endotoxins to help ensure consistency, reliability, and integrity across all research applications.
Where can I find the Certificate of Analysis (COA)?
Certificates of Analysis are available directly on each product page within the image gallery. Current and historical batch details—including lot numbers, manufacturing dates, expiration dates, and testing data—are also accessible through our Lab Results page.
Why aren’t all raw materials sourced exclusively from the USA?
Globally, the majority of active pharmaceutical ingredients (APIs)—including those used by U.S. pharmaceutical manufacturers and compounding facilities—are produced overseas. While domestic sourcing is prioritized when feasible, sourcing 100% of raw materials exclusively from the U.S. is not practical and is consistent with industry standards.
What matters most is that formulation, lyophilization, and third-party testing are conducted entirely within the United States, ensuring strict quality control and batch-level verification.
How are orders shipped?
All orders ship from our North Carolina warehouse via UPS. Customers may select Ground, 2-Day, or Express service at checkout. Orders over $125 qualify for free UPS 2-Day shipping. Every shipment includes full insurance at no additional cost.
Where do you ship?
We currently ship within the United States only. We do not ship to PO Boxes, international locations, military bases (APO/FPO), or U.S. territories.
What payment methods do you accept?
We accept all major debit and credit cards, including American Express. HSA and FSA payments are not accepted.
After checkout, customers must complete a secure Payment Authorization Form. Orders are not processed or shipped until authorization is completed. This process ensures PCI compliance and protects customer payment information.
Do you accept returns?
All sales are final. If there is an issue with your order, please contact support@rebelfitness.com within 7 days of delivery for assistance.
How should this product be stored?
Prior to reconstitution, store lyophilized compounds in a cool, dry location away from direct light. After reconstitution, research materials should be refrigerated to maintain optimal stability.
