Purus Peptides products are designated exclusively for Research Use Only (RUO) and are available solely to qualified researchers working in controlled laboratory settings. These products are not approved by the U.S. Food and Drug Administration (FDA) for human or veterinary applications, including clinical trials, therapeutic uses, or any form of consumption.

Purus Peptides complies with applicable regulations, including Section 503A of the Federal Food, Drug, and Cosmetic Act (FDCA), and limits product access to professional research purposes only.

Important Notice: Purus Peptides does not offer guidance, recommendations, or advice on product usage or applications. Researchers are fully responsible for consulting qualified experts to develop and follow appropriate research protocols.

At Purus Peptides, we are committed to delivering research peptides and compounds of the highest purity and quality. To achieve this, all our products undergo rigorous third-party testing using advanced analytical methods. Below, we outline the key testing techniques we employ to ensure our products meet the strictest standards for research applications.

• Mass Spectrometry Mass spectrometry is a powerful analytical technique used to determine the molecular composition of a sample. It works by ionizing peptide molecules and measuring their mass-to-charge ratio. This allows us to confirm the molecular weight and identity of our peptides, ensuring they match the expected chemical structure with high precision.

• High-Performance Liquid Chromatography (HPLC) High-performance liquid chromatography is a method used to assess the purity of our peptides and compounds. It separates the components of a sample based on their chemical properties as they pass through a specialized column. By analyzing the resulting chromatogram, we can verify that our products are free from impurities and contaminants, ensuring exceptional purity for research purposes.

• Amino Acid Analysis (AAA) Amino acid analysis is a technique used to confirm the composition and sequence of peptides. It involves breaking down the peptide into its individual amino acids and quantifying them. This process ensures that the peptide’s amino acid content aligns with its intended sequence, verifying both its structural integrity and quality.

Our commitment to third-party testing using these advanced methods guarantees that researchers receive peptides and compounds of unparalleled quality, reliability, and consistency for their scientific endeavors.

At Purus Peptides, we strive to deliver your order promptly and securely. Most orders are shipped via FedEx 2-Day Shipping, ensuring fast and reliable delivery. However, if your order is addressed to a P.O. Box, we will use USPS for delivery, and shipping times may vary depending on your location.

Please note that while we aim to meet estimated delivery times, shipping durations are not guaranteed due to factors beyond our control, such as weather or carrier delays.

If you have any questions or concerns about your order’s shipping status, please reach out to our customer support team at support@puruspeptides.com. We’re here to assist you!

Due to the specialized nature of our research peptides and compounds, Purus Peptides does not accept returns.
