About Pure Lot Research

Confidence starts with the lot.

Pure Lot Research supplies research-grade peptides to independent laboratories, universities, and contract research organizations. Every published COA is independently tested by a US-based third-party laboratory, with lot-specific results available for greater transparency and traceability.

Purity, documented
We publish each lot’s analysis under its own lot number, and it stays online. Lots whose certificates are still with the laboratory are marked pending on the product page.
Documentation first
Each vial carries a lot number. Its certificate of analysis is published online once issued and stays available, tied to that lot.
Handled with care
Packed carefully and tracked so what leaves our facility arrives intact.

How every lot is tested

A consistent process behind every product page.

01
Sourced & received
Each incoming lot is quarantined and logged against its supplier documentation before anything else.
02
Independently tested
Each lot is independently tested by a third-party laboratory for identity and purity. The analysis is documented in a lot-specific certificate, published in our online COA library once issued.
03
COA issued
Results are compiled into a certificate of analysis and matched to the lot number on the vial.
04
Verified & released
Each lot is reviewed against its supplier documentation and its current testing status before release. When the laboratory issues that lot’s certificate, we publish it in the COA Library under its lot number.

Frequently asked

Are these products intended for human or animal use?

No. Pure Lot Research products are sold strictly for laboratory research use only. They are not intended for human or veterinary use, consumption, diagnosis, treatment, or any clinical application.

How is each lot tested?

Each lot is submitted to an independent third-party laboratory for identity and purity testing. The testing methods, data, and lot information are documented in a lot-specific certificate of analysis.

Where can I view the COA?

Lot-specific COAs are published in our online COA Library. Each vial is labeled with its lot number — once that lot’s certificate is issued, it appears in the library under the same number.

How quickly will my order ship?

We aim to process orders within 1–2 business days, and every order ships with tracking — you’ll receive a tracking email as soon as your package is on the way.

Where do you ship?

We currently ship within the United States. Available shipping options and estimated delivery times are shown during checkout.

What if there’s a problem with my order?

Because these are research reference materials whose integrity depends on controlled handling and storage, we can’t accept returns of shipped products. If your order arrives damaged, incorrect, or incomplete, contact support@purelotresearch.com within seven days of delivery with your order number and photos — we’ll replace the item or refund it. If your order hasn’t shipped yet, contact us promptly and we’ll try to cancel or amend it.
