The ND-USA Quality Warranty

Our commitment to the scientific community is backed by a comprehensive guarantee of chemical purity, potency, and structural identity.

Purity & Identity Warranty

We warrant that every compound shipped from our facility matches the molecular identity verified by our in-house FTIR and HPLC testing. If a batch does not meet the specified purity threshold on its COA, we will replace the material at zero cost to the researcher.

Standardized Potency

We guarantee that the active bioactives (e.g., Ginsenosides, Salidroside) are present at the exact concentration listed on our labels. We utilize validated assay methods to ensure you receive the clinical strength required for accurate research outcomes.

Shelf-Life Stability

All Nootropics Depot USA products are warrantied to maintain their stated potency until the date of expiration, provided they are stored in accordance with our climate-controlled guidelines (cool, dry, and protected from UV light).

Contaminant-Free Guarantee

We warrant that all products have passed ICP-MS screening for heavy metals and microbiological plating for safety. Our thresholds for Lead, Mercury, and Arsenic are significantly stricter than standard USP requirements.

100% Satisfaction Guarantee

If you are not satisfied with the quality or integrity of your order, contact our support team within 30 days of delivery. As a leader in the research community, our priority is your data's accuracy and your research's success. We stand behind every milligram we distribute.
