Frequently Asked Questions

What is a COA Summary Report and why is it better than a single COA?

A traditional COA shows data from one test, once. Our COA Summary Report goes further: we compile results from multiple independent labs (1st & 3rd party) that tested the same batch we sell. Each section lists the lab name, date tested, and reported values (identity, quantity/mass, purity). When a lab tests multiple vials, we display the individual results and the average. Reports are sorted chronologically so you can see performance over time.

Why this is better:
• Higher confidence: Independent verification across labs reduces the chance of error from any single test.
• Batch-level relevance: We summarize data for the exact batch offered for sale—no generic or unrelated COAs.
• Outlier visibility: Showing all vial results (and averages) helps identify anomalies rather than hiding them.
• Consistency & transparency: A unified format with standardized fields makes results easy to compare.
• Data integrity: We never alter lab-reported numbers—our role is to compile, label, and present them clearly.

The result is a clearer, more transparent picture of quality than a single COA can provide, while maintaining our research-only compliance standards.

What are research peptides and how do you ensure quality?

Research peptides are synthetic amino acid chains designed for laboratory research purposes only. We ensure quality through rigorous sourcing from established manufacturers, proper storage protocols, and documentation available upon request. All products are intended solely for qualified researchers conducting lawful scientific studies.

Why does my lyophilized vial look misshapen or unusual?

This is completely normal! Lyophilized (freeze-dried) peptide "pucks" can appear cracked, broken, or irregularly shaped due to the freeze-drying process and shipping vibrations. The peptide remains stable and potent regardless of physical appearance. What matters is proper storage and reconstitution following your research protocols.

Do you provide Certificates of Analysis (COAs)?

Documentation may be available upon request for qualified researchers. We work with established suppliers who maintain appropriate testing standards. Contact us at **@************es.com with your specific documentation needs.

Are your products pharmaceutical grade?

Our products are research-grade chemicals intended for laboratory use only. They are not pharmaceutical drugs, dietary supplements, or FDA-approved substances. All materials are sourced from reputable suppliers for research applications only.

What does "research use only" mean?

"Research use only" means these products are exclusively for laboratory research by qualified professionals. They are NOT for human consumption, veterinary use, clinical applications, or any purpose outside legitimate scientific research. This designation is legally required and strictly enforced.

Can I use these products for personal health purposes?

Absolutely not. Our products are strictly prohibited for human consumption, self-administration, or any medical/therapeutic use. They are research chemicals for laboratory studies only. Using them for personal health purposes violates our terms and applicable regulations.

What age restrictions apply?

You must be at least 21 years old to purchase from Hacker Peptides. Additional state-specific restrictions may apply, particularly regarding products that could be construed as performance-enhancing substances. We comply with all applicable age verification requirements.

What are my responsibilities as a purchaser?

You must be a qualified researcher, comply with all local/state/federal laws, use products only for legitimate research, implement proper safety protocols, and ensure proper storage and disposal. You're responsible for understanding and following all applicable regulations in your jurisdiction.

How do you package temperature-sensitive products?

We use appropriate packaging methods to maintain product integrity during transit. Most lyophilized peptides are stable at room temperature for an extended period of time.

What shipping methods do you use?

We ship via reliable carriers with tracking provided. Domestic orders typically arrive within 3-7 business days. All packages are discretely packaged.

Do you ship internationally?

International shipping policies vary based on destination regulations. Contact us to verify shipping availability to your location. Customers are responsible for understanding and complying with their country's import regulations for research chemicals.

What if my package is delayed or Arrives damaged?

Contact us immediately at **@************es.com with your tracking information. If your product arrives damaged contact us with pictures of the shipping box and contents as soon as possible. We'll work with the carrier to resolve shipping issues and ensure you receive your research materials promptly.

What payment methods do you accept?

We accept major credit cards, zelle, and other secure payment methods. Payment options may vary based on order size and customer verification requirements. All transactions are processed securely.

Can I cancel or modify my order?

Orders can be cancelled or modified before processing and shipment. Contact us immediately at **@************es.com with your order number. Once shipped, orders cannot be cancelled or returned due to the nature of research chemicals.

Do you offer bulk pricing for institutions?

We work with qualified research institutions, universities, and laboratories on volume pricing. Contact us with your institutional requirements, and we'll provide a custom quote based on your research needs and verification.

How do I place a purchase order?

For institutional purchase orders, email us at **@************es.com with your requirements. Include your institution details, required products, quantities, and any special documentation needs. We'll guide you through our B2B ordering process.
