Frequently Asked Questions

Everything you need to know about peptide research

All Ultra Research peptides are independently tested to 99%+ purity using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry. A Certificate of Analysis from a U.S.-accredited third-party laboratory is included with every order and available on request at any time.
A CoA is an official testing document issued by an accredited laboratory. It reports the compound's identity, purity percentage, molecular weight confirmation, and any detected impurities. Each CoA from Ultra Research lists the lot number, test date, testing methodology, and the laboratory's accreditation number so you can verify the results independently.
Semaglutide is a GLP-1 receptor agonist peptide used extensively in metabolic and endocrine research. Tirzepatide is a dual GIP/GLP-1 receptor agonist. Both are supplied by Ultra Research as lyophilized research compounds for laboratory and research use only. Neither is intended for human or veterinary use.
Lyophilized (freeze-dried) peptides should be stored at −20°C or below when not in use. Keep them away from light, moisture, and repeated freeze-thaw cycles. Avoid storing reconstituted peptides for extended periods — aliquot immediately after reconstitution for best research results.
Properly stored lyophilized peptides are typically stable for 24 months or longer at −20°C. Specific stability data for each compound is documented in the accompanying CoA. Reconstituted peptides have a significantly shorter window and should be aliquoted and stored per your lab's standard operating procedures.
All in-stock orders placed before 2 PM EST are dispatched same business day. Standard delivery is 2–5 business days; expedited next-day shipping is available. Lyophilized peptides are stable at ambient temperature for short periods, but we include cold packs in all shipments for added protection during transit.
Ultra Research is a U.S.-based research peptide supplier committed to the highest documentation standards in the industry. Every compound we sell ships with a third-party CoA. We operate transparently — our testing results are verifiable, our lot numbers are traceable, and our team is accessible for research support. Trust is earned through documentation, not marketing claims.
No. All products sold by Ultra Research are strictly for Research Use Only (RUO). They have not been evaluated by the FDA and are not intended for human or veterinary use, consumption, or medical application. By purchasing, you confirm you are a qualified researcher using these compounds for legitimate laboratory research purposes only.
We accept returns on unopened, undamaged products within 30 days of delivery. Products damaged in transit are replaced or refunded at no cost under our standard shipment protection. For quality concerns, please contact our team with your lot number and CoA — we stand behind every batch we ship.
Our research support team is available by email at [email protected] and via live chat during business hours (M–F, 9 AM–6 PM EST). For urgent shipment issues, include your order number in the subject line for fastest resolution. We typically respond to all inquiries within one business day.
