Zenith Research

No real complaint about the Semaglutide vial or the paperwork, both were fine. Just be aware the packaging is bare bones, a thin mailer with the vial loose inside and no padding to speak of. It survived but I'd like a little more care.

Got my Ipamorelin in four days, vials sealed tight and the batch COA matched. Smoothest order I've had in a while.

Ordered the CJC-1295 and when it arrived I went looking for the certificate of analysis. What was in the box was a generic COA for the compound, not one tied to my actual batch number. I emailed Zenith to ask for the batch-specific report and it took most of a week to get a reply. Eventually they sent something over but it felt like pulling teeth for what should be standard. The vials looked okay otherwise, just disappointed in the testing paperwork.

The TB-500 vials themselves were fine, sealed properly and filled to the line. It just took nine days to arrive after I ordered, and tracking sat unmoved for most of that. Not terrible, just slower than I'd hoped for a domestic vendor.

First order of BPC-157 from Zenith and it showed up sealed with the COA tucked in the box. No drama, would buy again.

Ordered MK-677 and it was at my door in two days. COA matched the batch number on the vial. Reordering.

Been ordering BPC-157 from here for a while now. Domestic shipping is consistently a few days and the testing docs are always posted. Wish they kept TB-500 in stock more often.

Semaglutide arrived fast, vials clean and properly labeled. COA was easy to find. Checkout on the site was simple.

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.

Usually quick but my last order sat for almost a week before a tracking number showed up. Support replied eventually and apologized. Product was sealed and fine when it got here.

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.

Third order with Zenith. Ipamorelin and CJC both in stock, both shipped same day. Prices crept up a bit since summer but still reasonable.

Powder reconstituted clear and shipping was fast. My only gripe is the COA they linked looked generic rather than tied to my exact batch. Asked about it and they did send a newer one.

Retat showed up quick and the vial fill looked accurate. Third-party HPLC numbers were on the COA. No complaints.

Emailed with a question before ordering and got a real answer back fast, not a canned reply. Small operation but they clearly care. GHK-Cu arrived two days later.

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.

Product was fine and the COA checked out. Just a plain bubble mailer though, expected a little more for the price. Shipping itself was quick.

Tirzepatide order came well packed with an ice pack still cold. Free shipping was a nice touch. COA matched the batch.

Same day shipping is real here. Vials arrived sealed and labeled clean, lyophilized cake intact. The QR code on the vial pulled up the actual lab report which I appreciate.

Ordered the BPC-157/TB-500 blend and it showed up in three days. COA was right there on the product page, no chasing it down. Will order again.
