Frequently Asked Questions
Are your products FDA approved?
No. Our products are classified as Research Use Only (RUO) materials and are NOT approved by the FDA for diagnostic, therapeutic, or clinical use.
Do you source products from international manufacturers?
Yes, in some cases. While 90% of our products are sourced from U.S.-based manufacturing partners, certain compounds have limited domestic availability. To ensure these products remain available for our customers, 10% of our catalog is sourced from carefully vetted international manufacturers.
Every product we offer is rigorously tested to verify identity, net content, purity, conformity, sterility, and endotoxins. This expanded testing reflects our ongoing commitment to maintaining the highest possible standards for product quality and research integrity.
How do you test your products and where can I see the results?
Our products are tested using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) via reputable third-party testing companies in the US. Certificates of Analysis (COAs) are provided on our website for complete transparency and can be easily verified through the third-party testing site as well.

Orders placed before 12PM CST Monday – Friday are shipped the same day, excluding holidays, using FedEx Express 2 day delivery. Orders placed after this cutoff time are shipped the next business day.
Do you offer dosing or reconstitution advice?
