FAQ
Can I get a COA before I order? +
Yes. Check the product page gallery first. If you still can’t find it, contact support and tell us the exact product.
Why don’t you list every COA on one page? +
Keeping COAs on the product page helps avoid outdated documents and reduces mix-ups when batches change.
What does a COA usually show? +
Typical COAs include identity and purity-related results plus basic batch details. The exact fields depend on the lab and method used.
I can’t open the COA image. What should I do? +
Try refreshing the page or opening it on desktop. If it still won’t load, contact support and we’ll help.
Tip: If you’re on mobile and the COA feels small, download the image and open it to view the full size.
