I decided to try CHK CU after seeing a few people talk about it, and I'm honestly glad I did. I wasn't expecting anything dramatic, but after using it consistently for a few weeks, I noticed a real difference. It fit easily into my daily routine.

I've been using Tesamorelin for about a month now, and the experience has been great so far. Everything arrived well packaged, the instructions were easy to follow, and the quality gave me confidence right away. It's been simple to work into my routine, and I'm happy with my decision to give it a try. I'll definitely be reordering when it's time.

Everything researchers ask before ordering.

Every order is dispatched the same business day, and deliveries typically arrive within two business days. You will receive a tracking number as soon as the label is created.

Every order ships with the lyophilized vial, a tamper-evident seal, and a packing slip referencing the batch ID. The matching certificate of analysis is available on this page and in your account downloads after purchase.

Every batch is tested by an independent lab using HPLC for purity and LC-MS for identity. The COA is stamped with the batch number, test date, and lab name, and uploaded to this page before any vial from that lot ships.

Lyophilized peptides are stable at room temperature for short-term shipping but should be kept at −20°C for long-term storage. Reconstituted product should be refrigerated at 2–8°C and used within the window noted on the COA.

All major credit and debit cards through our secure checkout. We do not store payment information. Transactions are processed by a PCI-compliant gateway.

We offer a 30 day money back guarantee. If your order arrives damaged, does not match the COA, or you are not satisfied, contact us within 30 days for a full refund or replacement. Because of the research-use nature of these products, opened vials cannot be resold or restocked.

Email us at support@ascendbiolabs.com with your order number and we will get back to you quickly. Questions about handling, storage, or documentation are answered by people who work with the material directly.
