Frequently Asked Questions

Research peptides are synthetic amino acid chains used in scientific research to study biological processes. They are chemical compounds produced for use in controlled laboratory settings, academic research, and drug discovery pipelines. REZOLYX peptides are produced to pharmaceutical-grade standards and are intended exclusively for in vitro research use.

REZOLYX products are available to licensed researchers, academic institutions, pharmaceutical companies, and qualified research professionals. Purchasers must be 18 years of age or older and confirm that products will be used solely for legitimate scientific research purposes in compliance with applicable laws.

No. REZOLYX products are strictly for research purposes only. They are not intended for human or veterinary consumption, diagnostic use, or any purpose other than in vitro scientific research. Using research chemicals outside of a controlled laboratory setting is dangerous and potentially illegal. We do not provide dosing advice or any guidance related to human use.

All REZOLYX compounds are guaranteed to exceed 99% purity as measured by HPLC analysis. Individual batch purity results are documented in the Certificate of Analysis (CoA) included with every order. Many of our compounds routinely test at 99.4%+ purity.

Every batch undergoes a two-stage testing protocol:

• HPLC (High-Performance Liquid Chromatography): Determines purity percentage and identifies potential impurities
• Mass Spectrometry (MS): Confirms molecular identity by verifying the molecular weight and fragmentation pattern matches the target compound

Testing is performed by independent, ISO-accredited third-party laboratories. CoA documents are available for every product.

Yes. A batch-specific Certificate of Analysis is provided with every order. The CoA includes HPLC purity data, mass spectrometry results, molecular formula, CAS number, and storage recommendations. If you need a CoA before purchasing, contact our team and we can provide one for any product in our catalog.

Most REZOLYX peptides are supplied as lyophilized (freeze-dried) powder in sealed vials. This form maximizes stability and shelf life during storage and shipping. Specific formulation details are listed on each product page.

Browse our catalog, select the desired compound and quantity, and proceed through our secure checkout. We accept major credit cards and other payment methods. You will receive an order confirmation and tracking information by email.

Yes. We offer volume discounts for large orders and institutional accounts. Contact us at research@rezolyx.com with your requirements, institution details, and expected volume for a custom quote.

Due to the nature of research chemicals, we cannot accept returns on opened products. If you receive a product that does not match its stated specifications, contact us within 7 days of receipt with your CoA and we will work to resolve the issue, including replacement or refund as appropriate.

Orders are dispatched within 48 business hours. Domestic US shipping typically takes 2–5 business days. International shipping varies by destination, typically 7–14 business days. Expedited shipping options are available at checkout.

All shipments are packed discreetly in plain, unmarked packaging. Peptides are shipped with appropriate cold packs and insulation to maintain stability during transit. Products requiring refrigeration are clearly labeled with storage instructions.

Yes, we ship to most countries worldwide. It is the buyer's responsibility to ensure that importing research chemicals complies with local laws and regulations. REZOLYX is not responsible for customs delays or seizures resulting from import regulations in the destination country.

The legal status of research peptides varies by country and jurisdiction. In the United States, many research peptides are legal to purchase for research purposes when not intended for human consumption. It is the purchaser's responsibility to verify the legal status of any compound in their jurisdiction before ordering. REZOLYX provides products solely for legitimate research use.
