  • Manufactured using WFI (Water for Injection) grade water — the highest purity standard available
  • Lyophilized (freeze-dried) for maximum shelf stability during shipping and long-term storage
  • Full 36-hour lyophilization: controlled freeze at -40°C, primary sublimation, secondary desorption drying
  • Sterile filtration through 0.22µm PES membrane prior to dispensing into sealed vials
  • Independent HPLC and mass spectrometry verification by accredited third-party analytical labs
  • 30-day return window on all unopened vials · Discreet exterior packaging on every order
01
≥99% Verified Purity

Every production batch is independently tested by accredited third-party laboratories. We provide full Certificates of Analysis confirming compound identity and minimum 99% purity before anything ships. Verifiable directly with the testing lab using your unique batch key.

02
Batch Documentation

Complete batch-level records including HPLC chromatography data, mass spectrometry identity confirmation, purity percentage analysis, and appearance review. Transparency is built into every order — not an afterthought. We believe verifiable quality is the only acceptable standard.

03
Researcher Support

Our knowledgeable support team is available to assist with product questions, documentation requests, and order guidance. We work directly with researchers to ensure a smooth, informed experience. Live chat, email, and phone support throughout business hours.

Quality Control

Our Verification Process

I
Synthesis & Preparation

Peptides dissolved in WFI-grade water with mannitol and sucrose excipients. ESI process introduces sodium ions for ionization stability and characterization.

II
Sterile Filtration

Solution passes through a 0.22µm PES membrane, eliminating contaminants and ensuring pharmaceutical-grade cleanliness before vial dispensing.

III
Lyophilization

36-hour freeze-drying at -40°C. Three controlled phases ensure structural integrity, maximum potency, and long-term shelf stability of every vial.

IV
Third-Party Testing

Independent HPLC and mass spectrometry confirms compound identity and ≥99% purity. No batch ships without a fully verified, downloadable COA.

Frequently Asked Questions

Got Questions?

What are peptides?+
Peptides are short chains of amino acids that act as building blocks of proteins. They play crucial roles in biological processes and hold significant research potential across pharmacology, metabolic biology, endocrinology, and related scientific fields.
What are GLP compounds and how do they differ?+
GLP compounds are incretin-based research peptides targeting GLP-1, GIP, and glucagon receptors. Semaglutide (GLP-1S) is a single GLP-1 receptor agonist. Tirzepatide (GLP-2T) is a dual GLP-1/GIP receptor agonist. Retatrutide (GLP-3R) is a triple GLP-1/GIP/glucagon receptor agonist — the most advanced of the three. All are provided strictly for laboratory research purposes only.
How much bacteriostatic water should I use to reconstitute?+
Please use our Peptide Calculator tool to determine the correct amount of bacteriostatic water for your compound and desired concentration. Refer to our complete reconstitution guide for step-by-step instructions.
How do I verify my Certificate of Analysis (COA)?+
All products undergo rigorous third-party testing. Verify your COA by visiting the testing laboratory's verification portal and entering the task number and unique key found on your COA document. COAs are also available on each product page.
How long do peptides last and how should I store them?+
Our peptides are lyophilized (freeze-dried) for maximum shelf stability. Unopened lyophilized vials should be stored in a cool, dry location away from direct light. Once reconstituted with bacteriostatic water, refrigerate and use within the recommended window. See our storage guide for compound-specific recommendations.
What is your return and refund policy?+
We offer a 30-day return window on all unopened vials from the date of receipt. Log in to your account, navigate to the Orders tab, and submit a Return Request. Our team responds within 1–2 business days. Defective, damaged, or incorrect items: submit an Exchange Request Form upon receipt.
Do you provide medical advice or dosing guidance?+
No. PurePepPro provides compounds for research purposes only and does not provide medical advice, dosage guidance, administration instructions, or any protocols for human use. Please conduct independent research or speak to a licensed medical professional for health-related questions.
Do you ship internationally?+
We ship within the United States only — no international shipping available. We cannot ship to PO Boxes. Commercial and residential addresses only. We comply with all applicable federal and state regulations.
