About LIPEPS

Long Island Peptides

LIPEPS supplies freeze-dried (lyophilized) peptides for laboratory research. We are based on Long Island, New York.

A research buyer needs to know which material is available, which lot was tested, and where to check the report. Our catalog and certificate library put those details alongside the product.

Start with the lot record

A lot code identifies a batch. On Lab results, you can look up that code, read the published certificate of analysis (COA), and follow the laboratory verification link provided with the record.

Once your order is packed, its assigned lot appears on the order status page. Compare that code with the vial you receive and the laboratory report. A batch without a lab report is clearly marked before purchase. Older published lots remain available after they sell out.

The report is evidence of the tests it lists on the sample examined. It does not establish suitability for human or animal use.

First research purchase here

Start with How to read a COA. It explains identity, purity, the meaning of an untested field, and how to check a report with the laboratory.

Then review the Research use policy and browse the catalog. Product quantities describe the material supplied; they are not usage instructions. We can help with documentation or ordering questions through Contact.

Returning to LIPEPS

Use your account to find previous orders and order details. Guest checkout is also available, and the private link in each order email takes you back to its status page.

Check the current lot record when ordering again. A previous purchase and a new purchase may come from different batches.

Ordering and support

You can review payment options, shipping, and returns before placing an order. The Terms of sale explain the purchase conditions, and the Privacy Policy describes how order and account information is handled.
