Hi Michael, thank you so much for the 5-star review! We are thrilled to hear that your order arrived exactly as expected and that you found our service efficient. We look forward to serving you again soon at Onyx Biolabs.
I was able to see the COA online. The shipping was normal but I did order right before the weekend so I expected a little extra shipping time. I am pleased with my purchase.
