Here's exactly how we work so you can trust what you read.
Scientific Foundation
We read the clinical trials. 140+ studies reviewed for each major ingredient before we recommend anything.
Real Products, Real Money
We buy every product at full retail price. No free samples. No brand gifts. What you see is what we paid for.
Long-Term Testing
We test over 90 days minimum. Acute effects don't impress us — we want sustained, measurable improvement.
Our testing process in brief
Every candidate supplement goes through three stages: (1) Literature review — we check PubMed for human RCTs on the active ingredients. (2) Product vetting — we verify label accuracy against lab reports where available, and rule out underdosed or proprietary blend products. (3) Self-testing — we take the product for a minimum of 30 days at the recommended dose before forming a view.
