Key Factors When Choosing a Nootropic Supplier

1. Purity and Testing

Always look for suppliers that publish third-party lab tests. Contaminants, fillers, or inaccurate dosages can render a nootropic ineffective or even dangerous.

✅ Tip: Avoid vendors that hide their COAs or claim “proprietary blends.”

2. Customer Feedback and Transparency

Vendors with active user communities, strong online reputations, and consistent shipping performance are more likely to provide authentic compounds.

3. Product Range and Accessibility

Top-tier vendors not only offer racetams and cholinergics but also cutting-edge peptides, adaptogens, and dopamine agonists. Diversity ensures you can tailor your nootropic stack effectively.
