FAQ's

Frequently Asked Questions

What Are Research Peptides?

Research peptides are laboratory compounds intended exclusively for scientific and analytical research by qualified professionals. They are not approved for medical, diagnostic, or therapeutic applications.

Are Your Products Third-Party Tested?

Yes. Each batch is submitted for independent third-party analytical testing. Batch-specific Certificates of Analysis (COAs) are maintained and made available for review.

What Is a Purity Report?

A purity report, also referred to as a Certificate of Analysis (COA), is a laboratory document showing the tested purity and analytical results for a specific batch.

What Does “Research Use Only” Mean?

Research Use Only means the products are intended strictly for laboratory, educational, and analytical research purposes and are not for human or veterinary use.

What Does Lyophilized Mean?

Lyophilized refers to a freeze-drying process used to preserve peptide stability and extend shelf life during storage and transport.

How Are Products Shipped?

Products are securely packaged for shipment. Orders are typically processed within 1–2 business days after payment confirmation, and tracking information is provided when available.

How Do I Access Purity Reports?

Batch-specific Certificates of Analysis (COAs) can be accessed through the applicable product listing or by scanning the QR code on the product label when available.

Are All Products Tested?

Yes. Each batch is submitted for independent third-party analytical testing, with batch-specific Certificates of Analysis (COAs) maintained for review.

How Should Products Be Stored?

Products should be stored according to the storage information provided with each product. Keep materials protected from excessive heat, moisture, and direct sunlight.

Will Additional Peptides Be Added Later?

Yes. Additional research products may be added as inventory becomes available and appropriate testing and documentation are completed.
