How To Read A Lab Certificate In Two Minutes

Lorem ipsum dolor sit amet, consectetur adipiscing elit. A certificate of analysis is two pages of figures; four lines of it answer almost every question about a bottle.

Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo.

1. The Batch Code

The code on the certificate must match the code beside the barcode on your pack. Neque porro quisquam est, qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit.

If the code on the paper is not the code on the bottle, the paper tells you nothing about the bottle.

2. CBD Against The Label

The measured CBD should sit within ten percent of the label. Ut enim ad minima veniam, quis nostrum exercitationem ullam corporis suscipit laboriosam, nisi ut aliquid ex ea commodi consequatur.

3. THC Against The Limit

Delta-9 THC must be no more than 0.3% by weight. At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque corrupti.

I checked my gummies against the certificate after reading this. 25.8 mg against 25 on the label.
