James at Zenith is the best. After my first order, I haven't looked back. I've yet to find a more trustworthy and transparent vendor for my research. Up to date and easy to find and navigate COAs, great pricing and top tier customer service with 2 day shipping.

Safety, Customer Service, and Purity is their number one Priority
From start to door step, my experience was PERFECT! First of all, COAs, the MOST IMPORTANT! Every COA listed on each product page, the purity and actual compound levels in each are listed next to each product, these are some of the purist I have seen! EVEN the ZB BAC water has a COA, specially made in the USA for their clients! Next is pricing, you CANNOT BEAT the pricing for the purity of these research compounds. Products are easily located and easy to checkout! I personally had a wonderful experience with the owner. Safety is my number one concern and he was able to answer any and all of my questions quick, like withing 5 minutes of me reaching out. Shipping, everyone gets 2 day shipping, IT IS FAST! Quality of packaging, and the compounds, were second to none. Everything in its own little box with plastic inserts to keep them safe and then in a bubble wrap package. The quality of each product is spot on. This is only ONE of TWO companies I trust with my research materials! If you don't give them a shot, you are missing out BIG TIME!!! James, Ty for your continued caring and quality. I know that safety and purity is your number one priority! You have a customer for LIFE!!!
