A small supplier that shows its work
Molecula Labs is a founder-run US company selling research peptides for laboratory use. Every in-stock lot is tested by an independent lab, every result is published, and every message gets a reply within one business day.
Buying research peptides often means taking a supplier’s word for what is in the vial. We would rather show you the lab report, tell you which lab wrote it and let you check it yourself.
Who we are
Molecula Labs LLC is a small, founder-run company registered in Virginia. We sell freeze-dried research peptides and laboratory diluent to researchers and institutions in the United States, for in-vitro laboratory research only. Orders ship from the US in plain packaging.
How a lot is chosen
- We carry one lot of each size at a time, and every vial in it carries that lot number.
- What we order next is shaped by researchers: the restock vote on our certificates page is read before every order goes in.
- A new lot is held back from sale until its report comes back. Until then, that size can only be pre-ordered.
How it is tested
Every lot we stock goes to an independent US laboratory, either Freedom Diagnostics or Kovera Labs. A lot is only sold once it passes.
Each certificate lists the methods and results for its own lot. If a lot was screened for something, the result is on that lot’s report, and nothing is claimed for a test that was not run.
How results are published
Every released lot is on our certificates page with its purity, net content, lab and the full report. Each card also gives the lab’s own lookup code, so you can confirm the report on the lab’s website without asking us. The certificate for your lot goes in the box with your order.
The lot we didn’t sell
Our first Tesamorelin lot, ML-002, came back from the lab with no Tesamorelin detected. There was nothing to measure, so it failed. That lot never entered inventory and was never sold. We published the failed report anyway, and it is still on the certificates page next to the lots that passed.
Its replacement, lot ML-002.1, came from a different supplier and passed at 99.11% purity. We publish the fails because a page that only ever shows passes tells you nothing about how hard the testing is.
What we will and won’t do
- We will answer questions on specifications, purity, solubility, storage and orders.
- We will replace or refund anything that arrives damaged, wrong or missing, as set out in our refund policy.
- We won’t advise on experimental design or any use of our products. Everything we sell is for laboratory research only and is not for human or animal consumption.
