Most brands describe their testing. We attached the certificates.
Who made your supplement, where, how it was tested, and by whom. Most brands cannot answer those questions without a phone call to a contract manufacturer. We answer them on this page, with the certificates attached.
Six questions every supplement brand should be glad to answer.
You are swallowing these products. Many people do not know they can ask exactly how a supplement was made and tested, and a brand that hesitates on any of these questions has told you something. Here is the list, and here is where we stand on each one.
The questions
Where ND stands
Our founder built the factory and the lab because the ones we hired kept cutting corners.
Building your own facility is expensive and complex, so almost nobody does it.
When Nootropics Depot started, we relied on contract manufacturers and outside labs. That is how the industry works, because owning production and testing is a serious investment. Then the problems started: corners cut, batch specifications that did not match reality, and on more than one occasion contaminated product delivered as finished goods.
If we wanted products we would give to ourselves and our families, we could not keep trusting third parties to make them.
Our founder built the manufacturing company and the testing lab himself.
Paul built Supplement Logistics, our dedicated manufacturing company, and Omnient Labs, an independent ISO-accredited analytical testing laboratory. They are separate legal entities with separate teams, all owned and overseen by the founder, so quality, cGMP compliance, and the independence the certifications require are held in one place.
Both companies also manufacture and run lab work for other brands. Nootropics Depot is the retail side of a larger operation.
We take these products ourselves, and we give them to our friends and families.
That is the standard behind every decision on this page. By owning and managing each step, our founder can stand behind what you are putting into your body, because it is the same thing he and his family take.
Lab testing is the reason Nootropics Depot started. Pushing those standards forward has been the job every day since.
From a bioassay in our lab to a certificate on your product page, in four steps.
Formulation and bioassayNootropics Depot
Every product begins with careful thought and bioassaying by our team, including our product specialist Emiel and our CEO Paul. A formula has to make mechanistic sense and show activity in the lab before it goes any further.
ManufacturingSupplement Logistics
The formulation team at Supplement Logistics takes over: ingredient sourcing, capsule and tablet manufacturing, bulk powders, bottling, and labeling under one roof in a cGMP, FDA-registered facility in Tempe.
TestingOmnient Labs
The analytical chemists at Omnient Labs put each batch through identity, potency, heavy metal, residual solvent, microbiological, and disintegration testing, on UPLC instrumentation built for pharmaceutical work, so the label matches what is inside.
The certificate of analysis goes on the pageBefore you buy
The batch results are published on the product page, alongside a research snapshot of the studies behind the formula, reviewed by our independent Scientific Advisory Board. None of it is held back until someone asks.

Formulation, manufacturing, and testing sit next to each other in the Valley of the Sun, which turns out to be a fine place for a supplement company as long as the air conditioning holds. And yes, it is a dry heat.
Four things you get without asking, because a company that makes you ask has already answered.
Many companies use the word "transparency" in their marketing. We would rather show you the documents.
Our commitment goes beyond the label. It is built into how the products are made: clear, detailed ingredient lists, published batch testing, and accessible research snapshots on the science behind each formula. Everything we tell you is meant to be checkable.
If a question about one of our products is not answered on its page, ask us. That is the standard we would hold any brand to, so it is the one we hold ourselves to.
