Frequently Asked Questions

What is a Certificate of Analysis (COA)?

A COA is an official document from an independent, third-party laboratory that verifies a product’s identity, purity, and potency. It confirms that each batch meets our strict quality and safety standards.

Where can I find my product’s Lot Number?

The Lot Number is printed on your product’s label or packaging — usually near the expiration date or barcode. Enter that number in the search field above to view the COA for your exact batch.

Why does Vivazen® provide COAs?

We believe in full transparency. Our COAs allow you to see exactly what’s in your product — and what’s not — so you can trust that every batch meets the same high standards for safety and consistency.

I’m a retailer. Do I need a COA for compliance?

It depends on your region. Many retailers and distributors are required to keep COAs on file to meet state and federal regulations. You can download and store any COA directly from this page for your records.

How often are products tested?

Every production batch is independently tested before release. This ensures that all Feel Great Botanics products consistently meet specifications for purity, potency, and safety.
