Primeval Labs joins the Stack3d Certified supplement testing program

primeval labs stack3d certified

Since relaunching it last year, our revamped Stack3d Certified program has grown quite a bit. We now have a total of seven open and honest supplement companies participating thanks to the newest addition to the program who just jumped onboard for 2019 with Primeval Labs.

For those of you unfamiliar with the Stack3d Certified program, it is our third-party testing certification for fully transparent supplement companies. How it works is, after brands sign, we purchase a random product from its lineup from a random retailer, and send it straight to the lab.

Our lab tests for a supplement’s main ingredients, then when the results come back, we compare them to what the product claims on its label. If everything checks out the brand becomes Stack3d Certified. We do that testing process four times per year, each time picking a different product.

As mentioned, Primeval Labs has joined Stack3d Certified for 2019 after it passed the first round with its protein powder Isolit. You can see our full list of brands currently participating in the program at, where you can also look forward to seeing more names soon.
