The Neuro-Peak formula in this site’s earlier review differs substantially from Zhou’s current product description. Those versions must not be merged into one ingredient list.
This review examines the formula recorded in our earlier coverage. The archived amounts below are not confirmation of the label, stock, price or purchase terms available today. This editorial revision does not report a new personal trial or laboratory test.

Why the version distinction matters
The historical table below lists St John’s wort, DMAE, carnitine, glutamine, a phosphatidylserine complex, ginkgo, vinpocetine, bacopa and huperzine A. Zhou’s current product description instead highlights 240 mg ginkgo with vitamin B12, bacopa, rhodiola and other ingredients. Its own Q&A also discusses a new formula.
The archive does not establish the exact date or batch of every change. This page therefore preserves the earlier table as historical context and points to the manufacturer for the current pack, rather than presenting the old St John’s wort blend as today’s product.
Formula recorded in the earlier review
The table preserves the earlier ingredient record for comparison, with obsolete Daily Value percentages omitted. Use the current pack label for a purchase decision. These are recorded label amounts, not dosing instructions.
Neuro-Peak Ingredients | |
| Ingredients | Amount Per Serving |
| St. John’s Wort (as 3% extract) (flower heads) | 250 mg |
| Dimethylaminoethanol Bitartrate (DMAE) | 50 mg |
| N-Acetyl-L Carnitine HCl | 50 mg |
| L-Glutamine | 150 mg |
| Phosphatidylserine 4% Complex (consisting of Lecithin and Phosphatidylserine) | 125 mg |
| Ginkgo Biloba (as 24% extract) (leaf) | 50 mg |
| Vinpocetine (seeds) | 2 mg |
| Bacopa Monniera leaf extract (20% bacosides) | 100 mg |
| Huperzine-A (aerial plant) | 10 mcg |
The phosphatidylserine complex is not all active PS
The older entry says 125 mg of a 4% phosphatidylserine complex. If that percentage refers to PS content, the calculated PS amount would be 5 mg, not 125 mg. This is an interpretation of the archived specification, not independent verification of a capsule.
That distinction illustrates why ingredient-material weight and active-component weight must remain separate. The original review’s dose judgments and suggestion to increase servings were not a reliable response to this uncertainty.
The historical St John’s wort warning
If a pack contains St John’s wort, its interaction risks matter. NCCIH warns that it can interact with many medicines, reducing some drugs’ effects or causing serious adverse effects. That is more important than describing the old formula as a gentle mood booster.
This warning applies to the ingredient-containing version; it should not be attributed to a newer formula merely because the brand name is unchanged. Always use the actual ingredient panel when checking interactions.
What “physician formulated” does not establish
A formulation claim is not proof of a clinical trial, safe use for every age group or prevention of cognitive decline. The earlier promises to restore cognition and the advice to double servings have been removed. This review does not report medical review or a personal product test.
Editorial assessment
For Neuro-Peak, identifying the exact formula is the first task. The old nine-ingredient record has historical value, but current product assessment should use Zhou’s current pack and evidence matched to that version.
