I feel like I am in a partnership with Green Scientific. Our company owns a hemp farm and grow, extract, formulate and package. Every encounter with Green Scientific I always felt the wanted the best for our organization and partnered with us to find the solutions we needed. Highly Recommend!

Fast, reliable and easy to track receipt and progress of lab order status. Report formats are very professional and great for displaying on our website for CBD testing results. Only improvement - provide a brief consultation option for additional fee to briefly discuss results and findings with a lab expert.

Green Scientific is a great lab. The team is smart, leading the industry to highest quality standards and full-service, quickly and thoroughly. This team delivers.

I rarely give 5 stars because I think of 5 stars like a 4.0. Every single transaction with GSL has been spot on. Their staff, their product, their customer service... it's all done with absolute excellence. GSL is the standard, I just won't go anywhere else... I can count on them.

Our company started using Green Scientific Labs services a little over a month ago and we are very pleased with the turnaround time for the COA's, 3-4 days from the times received in the lab since we are getting the results. They have super friendly website that saves all your COA's in place for future references. Recommended!

An excellent web portal makes adding new samples, checking the status of existing samples, and downloading PDF formatted COAs, easy to do!! Affordable sample analysis, and full range of testing options, including cannabinoid potency, pesticides, micro, and heavy metals are available. Friendly staff have been attentive any time I have needed questions answered, technical or otherwise .
