Research Data

Peptides are short chains of amino acids linked by peptide bonds, typically comprising 2-50 amino acid residues. They serve as signaling molecules throughout the body, regulating processes from tissue repair and immune response to hormone secretion and neurotransmission. Unlike larger proteins, peptides are small enough to penetrate cellular membranes more readily, making them valuable tools in biomedical research.

All AscendRx products are strictly for laboratory research use only and are not intended for human consumption. Each product ships with a detailed certificate of analysis (COA), recommended reconstitution protocols, and storage guidelines. Researchers should follow established laboratory safety practices and institutional protocols when handling research compounds.

AscendRx maintains a minimum purity threshold of 98.7% across all catalog compounds, with most products exceeding 99%. Purity is verified through reversed-phase HPLC analysis performed by independent third-party laboratories. Complete analytical data — including chromatograms and mass spectra — is available on each product’s Certificate of Analysis, accessible from the Lab Reports page.

Certificates of Analysis for every batch are available on our Lab Reports page. Each COA includes HPLC chromatograms, mass spectrometry data, batch numbers, and testing dates. You can also access your order-specific COA directly from your My Account dashboard under Order History. If you need a COA for a specific batch not listed, contact our support team with your order number.

All orders ship via temperature-controlled logistics to maintain compound integrity. Standard shipping (3-5 business days) is available for lyophilized products. Solution compounds and temperature-sensitive items ship via expedited cold-chain service (1-2 business days) with insulated packaging and gel ice packs. Tracking information is provided for all shipments.

AscendRx products are research-grade compounds manufactured under controlled laboratory conditions. While we adhere to principles aligned with Good Manufacturing Practice (GMP), our products are classified as research chemicals, not pharmaceutical preparations. They undergo the same analytical testing methods used in pharmaceutical quality control — HPLC, mass spectrometry, and endotoxin assays — but are intended exclusively for in vitro research and scientific investigation.

Storage requirements vary by formulation. Lyophilized peptides should be stored at -20°C for maximum stability (up to 24 months), or at 2-8°C for short-term use (up to 30 days). Solution compounds are stable at room temperature (15-25°C) when protected from light. Once reconstituted, peptides should be aliquoted to avoid freeze-thaw degradation. Detailed storage instructions are included with each shipment and on the product COA.

Yes — AscendRx ships to most countries worldwide. International shipments are fully insured and include customs documentation. Delivery times range from 5-10 business days depending on destination and customs processing. Please note that import regulations for research compounds vary by jurisdiction; it is the buyer’s responsibility to verify that ordering and receiving research peptides complies with local laws and institutional policies.
