About Thesis

Thesis is a nootropics brand founded in 2021, making it a relatively new entrant to the market with 5 years in business. Thesis operates as an independent company based in the US. They focus on providing supplements designed to enhance cognitive function.

Product Specialization

Thesis specializes in nootropics. These supplements are designed to improve focus, memory, and overall cognitive performance. Thesis offers a range of formulations targeting different cognitive goals.

Testing & Certifications Explained

Thesis is GMP Certified, which means their manufacturing processes meet certain quality standards. However, Thesis does not appear to be third-party tested. Third-party testing provides an extra layer of assurance that the product contains what the label claims and is free from contaminants. The absence of third-party testing means consumers must rely solely on the brand's own quality control measures, making it harder to verify the product's contents.

How Thesis Compares

Compared to competitors in the nootropics space, Thesis's Trust Score of 65/100 places it in the middle range. For example, a brand like Onnit (Trust Score 78) may have higher trust marks due to more transparent testing. Other brands like Nootropics Depot (Trust Score 70) also demonstrate a commitment to testing that Thesis currently lacks. Consumers often look for third-party tested supplements to ensure quality and safety.

Buying Guidance

Given that Thesis does not appear to be third-party tested, consumers should exercise caution. Purchase directly from Thesis or authorized retailers to ensure product authenticity. Always carefully review the ingredient list and consult with a healthcare professional before starting any new supplement regimen. Consumers should also monitor for any adverse reactions after taking Thesis products.
