Question 1

What testing methods do you use to verify purity?

Accepted Answer

All PepHQ products are tested using HPLC-UV-MS (High-Performance Liquid Chromatography with UV and Mass Spectrometry detection). This industry-standard method provides accurate purity verification and molecular weight confirmation. Each batch is tested by independent, USA-based laboratories to ensure quality and consistency.

Question 2

Is a Certificate of Analysis (COA) available?

Accepted Answer

Yes, Certificates of Analysis are available upon request. COA results are displayed on each product detail page, showing detailed purity results, testing methodology, and batch verification. If you need the full COA document for your records, please contact us and we will provide it.

Question 3

How should research peptides be stored?

Accepted Answer

Lyophilized peptides are stable at room temperature for several weeks when stored in a dry, sealed container away from light and moisture. For extended storage, refrigeration (2-8°C) or freezing (-20°C) is recommended. All products sold for research use only.

Question 7

Do you ship internationally?

Accepted Answer

Currently, we ship within the United States only. We are working to expand international shipping to select countries. Please contact us if you are located outside the US and we can discuss options or notify you when international shipping becomes available.

Question 8

What payment methods do you accept?

Accepted Answer

We accept Zelle and Venmo for payment. Due to payment processing restrictions in the research peptide industry, traditional credit card processors often classify peptide products as 'high-risk,' even for legitimate research-use-only suppliers. Using Zelle and Venmo allows us to ensure reliable service without payment disruptions, keep prices competitive by avoiding 3% processing fees, and provide you with secure payment options through platforms you already trust. After submitting your order inquiry, we will provide a detailed quote and payment instructions. Payment must be received before your order is processed and shipped.

Question 9

What is your return and refund policy?

Accepted Answer

Due to the nature of research peptides, we cannot accept returns once products have shipped. However, if you receive a damaged product or have concerns about product quality, please contact us within 72 hours of delivery with photos. We will work with you to resolve any quality issues, including replacement or refund if warranted.
