Thirty days is roughly the minimum over which a formula like this can be assessed at all, and it is still short of what the Bacopa research used.
What to compare
If you recorded a baseline, compare the last two weeks of the bottle against your pre-supplement fortnight on whatever you measured - afternoon clarity rating, hours slept, task completion, or a simple timed recall task. If you did not record a baseline, be honest that you are comparing against a remembered impression, which is reconstructive, biased toward confirming what you already believe, and not reliable enough to justify a bulk purchase.
Reading the difference honestly
Look for a change larger than your normal variability. If your daily clarity ratings ranged from four to eight before you started, a six now means nothing. Consider what else changed across the month - season, workload, sleep, stress, illness, a holiday. Any of these can produce more variance than a supplement. And note that thirty days is short for this formula: the Bacopa trials that produced the memory findings ran to roughly twelve weeks, so a null result at thirty days is genuinely ambiguous rather than conclusive.
Looking at the Cognizil official website? Pricing starts at $49 per bottle on the 6-bottle tier.
See Cognizil PricingThe decision, and the deadline
This is where the refund window bites. The stated guarantee is 60 days from purchase, so at day 30 you have roughly a month to decide and act - less if shipping took a week. Do not drift past it while waiting for the twelve-week ingredient timeline to play out, because that timeline runs past the deadline. If the assessment is positive and you intend to continue, the bundle tiers become worth considering. If it is genuinely neutral, stopping is reasonable and the sunk cost of one bottle should not commit you to five more.
Pros and cons
Pros
- Thirty days is a reasonable minimum for tolerance and adherence assessment
- One bottle sits comfortably within the 60-day guarantee
- A recorded baseline makes the assessment genuinely informative
Cons
- Thirty days is short relative to Bacopa's twelve-week research timeline
- Most people have no baseline and compare against memory
- Confounding from season, workload and sleep is common over a month
- The refund deadline arrives before a full evaluation is possible

Verdict
Compare against a recorded baseline, look for a change larger than your normal variability, and make the continue-or-refund decision inside the window - the fair evaluation period for this formula is longer than the guarantee covers.
