Frequently Asked Questions
Everything you need to know about peptide research
All Peaked peptides are guaranteed 99%+ pure. Each batch is independently tested by accredited U.S. laboratories using HPLC and Mass Spectrometry. We provide a Certificate of Analysis with every order showing exact purity percentages, molecular weight verification, and amino acid sequence confirmation.
A Certificate of Analysis is an official lab document that verifies your peptide's quality. Key sections include: Purity (should be 99%+), Identity (confirms correct peptide via mass spec), Appearance, and Endotoxin levels (should be below 1 EU/mg). Each CoA is batch-specific and available on product pages.
Bacteriostatic water (BAC water) is sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth. It is a standard laboratory supply used in research settings. We offer pharmaceutical-grade BAC water in our accessories section.
Lyophilized (freeze-dried) peptides are very stable. For short-term storage (under 3 months), room temperature in a cool, dark place is fine. For long-term storage, refrigerate at 2–8°C or freeze at −20°C. Avoid repeated freeze-thaw cycles. Properly stored lyophilized peptides can remain stable for 2+ years.
Orders are processed within 0–2 business days. Standard shipping takes 3–5 business days from fulfillment. Every order includes free shipment protection. Lyophilized peptides don't require cold shipping—they're stable at room temperature. All orders ship in discreet, unlabeled packaging.
We offer a 60-day money-back guarantee. If you receive a damaged product, incorrect item, or a peptide that doesn't meet our purity standards, contact us for a full refund or replacement. Due to the nature of research materials, we cannot accept returns on opened products unless there's a quality issue.
All Peaked peptides are sold strictly for research, laboratory, and educational purposes only. They are not approved for human consumption, veterinary use, or any therapeutic application. By purchasing, you confirm you are a qualified researcher and will use products in accordance with all applicable laws and regulations.
