Who We Are

Quantum Four Labs is a Contract Development and Manufacturing Organization (CDMO) specializing in the production of Active Pharmaceutical Ingredients (APIs).
Our current focus is on small molecule APIs, but we can manufacture to specifications a significant amount of product at large or small scale.
A CDMO manufactures APIs to order when needed on a per purchase or on a contract basis. Our company maintains a full US FDA Pharmaceutical Manufacturing License (3017-1035-87).
We ensure all the materials you desire are manufactured to the highest standards of GMP production in accordance with all FDA rules and regulations.

Key Features

Made in the USA. No really, we are based in Los Angeles, CA.
It’s not that there are not great manufacturers all over the world, but we adhere to the highest standards of the FDA and pride ourselves on our holistic processing methods. We are also based in an area where shipping to a US Company means no logistical challenges and shipping to anywhere in the world is just a flight away. We then adhere to Good Distribution Practices (GDP) for the movement of all our products to our clients.
Not just small. Though we have specialized in small molecule APIs please don’t hesitate to reach out.
We have specialties in making multiple types of products including biologics, peptides and more. It’s part of our mission to be able to serve as much of the pharmaceutical community as possible.


Manufacturer not broker.
We are the manufacturer of the products that are requested by you. We do not trade APIs.
Support
We offer end-to-end support from order to delivery. Each customer is able to stay apprised of the production progress, shipping and delivery status, in order to plan their own production properly.
