Thesis
Thesis is worth a look.
4 personalised formula blends per month -- rotate until you find what works. Best for people who want to experiment. US only.
What it does
Thesis is a personalised nootropic subscription service that sends you four different formula blends each month -- Energy, Clarity, Logic, and Motivation -- along with access to a nootropics coaching service. Rather than a single fixed formula, Thesis lets you rotate blends on different days to find which works best for your specific cognitive profile.
How it works
Each Thesis blend targets a different cognitive mode. Energy blend: stimulating compounds (Zynamite, Dynamine, Ashwagandha) for high-output days. Clarity blend: cholinergics and focus ingredients for clear thinking. Logic blend: memory and processing speed ingredients. Motivation blend: dopaminergic support. Each blend has a caffeine-free and caffeinated option. The personalisation model allows you to match your cognitive demand of the day with the appropriate formula.
What to expect
First month: expect an experimentation period. You'll rotate through 4 blends, 7 days each, to assess which has the most noticeable effect for you. Energy blend effects are immediate (stimulating compounds work within 30-60 minutes). Clarity and Logic blend effects build over 2-4 weeks. Coaching service adds value for users who want guidance on optimising their protocol. Not suitable for EU buyers (US only storefront).

Ingredient quality
Number and quality of evidence-graded ingredients. Trademarked extracts and standardized actives raise this score.
Dosing vs. clinical evidence
How many ingredients meet their clinical-trial dose. Underdosing flagship actives is the biggest score deduction.
Formula transparency
Full disclosure of every ingredient at its exact dose. Proprietary blends are scored as opaque.
Value for money
Cost per month relative to per-serving clinical doses delivered. Cheaper products with underdoses score lower.
Brand trust
Brand reputation, third-party testing, refund track record, and Trustpilot signal across multiple years.
