Zenith Research

Got my Tirzepatide order in 3 business days which was faster than expected. Product came vacuum sealed with a recent test date. Haven't had issues with reconstitution. Pricing is competitive compared to other vendors I've used. Will likely reorder.

Ordered Tirzepatide from Zenith Research and it arrived in 3 days with FedEx Express. Vial was packaged in a hard plastic case with foam padding and a gel ice pack that was still cold. COA included with 99.3% purity results. Lyophilized powder looked perfect, reconstituted cleanly with no residue. Price was for 10mg which is competitive for Tirz. Website is modern and easy to use, checkout was smooth. They sent tracking info within an hour of ordering. Only thing that could be better is they charge for shipping, while some vendors offer free shipping over a certain amount. Still, quality and speed make up for it.

Ordered Epithalon and DSIP together for a research project. Both came with clean COAs showing good purity numbers. Packaging was professional with proper labeling. My only complaint is their customer service took about 36 hours to respond to a pre-order question, which felt slow. Once they replied though, they were helpful and knowledgeable. Products themselves performed exactly as expected in our testing protocols. Would order again but hope they speed up response times.
