Understand the window first
The seller states a 60-day money-back guarantee with refund requests made after at least 30 days of use. That means your decision point is between day 30 and day 60. Plan for it.
Day one: write three things down
Pick two or three specific, boring things you can notice. Examples: how often you lose your thread on a call, how heavy your head feels at 3 p.m., how quickly a name comes back. Write them down with a 1-to-5 score. Without this, week eight will be a guess.
What people commonly report, week by week
Illustrative only. Not a clinical measurement. Many people notice less or nothing.
Weeks 1–2
Expect little beyond a possible mild warmth from the niacin. Lock in the habit: one capsule, 8 oz of water, 20 to 30 minutes before breakfast.
Weeks 3–4
The most common early comment is a lighter late afternoon. Score your three items again at day 28.
Weeks 5–6
This is where most positive testimonials sit. Word recall and holding a thought are the two things mentioned most. Score again at day 42.
Weeks 7–8
Decision time, still inside the window. Compare day 1, 28, 42 and 56. If nothing has moved, request the refund before day 60.
Do it right
- Buy the 3-bottle bundle so you are not judging on one bottle, and buy on the official site so the guarantee applies.
- Keep the confirmation email and order number.
- Same time every day. Missed days blur the picture.
- Do not change coffee, sleep or exercise habits mid-trial; you will not know what caused what.
- Decide on your notes, not on how you feel the morning you check.
Strengths and weak spots, plainly
Strengths: every amount printed, two forms of each amino acid, no stimulant, one-time purchase, a written refund window. Weak spots: maintenance-level amounts next to trial doses, no clinical study of the finished capsule, slow by design, online only.
Who should not run this trial at all
Anyone hoping it will treat a diagnosed memory condition. Anyone on blood-pressure medicine, nitrates or erectile dysfunction medicine who has not spoken to a doctor. Anyone under 18, pregnant or nursing.
