Verify your Neuro Serge bottle and the source you bought it from
Two things worth checking before you swallow anything: that the bottle came from the current production run, and that the site you bought it from is the one the manufacturer actually authorised. Both checks are on this page.
Neurosergesupplement.net is the authorized online distribution portal for Neuro Serge for the 2026 production cycle, and the primary reference point for order fulfillment, batch documentation, and product verification.

Six checks on the source
- 1
Confirm the domain
The authorized address is neurosergesupplement.net, spelled exactly that way. Subdomains, hyphenated variants and other extensions are not part of the authorized 2026 distribution, whatever they claim on the page.
- 2
Check the connection
Look for the padlock and a valid certificate before you type anything into a form. If a browser warns you, stop there and come back through a search result rather than a link someone sent you.
- 3
Match the lot number
Lot 2608-NSG417 is the run shipping now. Compare it against the lot printed on the base of your bottle. If they do not match and you ordered recently, contact support before you take anything.
- 4
Use the published contacts only
Support runs through support@neurosergesupplement.net and +1 (207) 519-4260. We never ask for card numbers, passwords or wallet details by email, and nobody from this portal will ever ask you to pay by wire transfer or gift card.
- 5
Confirm the checkout page
Payment is handled by the authorized checkout partner. The page will show a secure connection and an itemised order summary before anything is charged.
- 6
Treat this portal as the record
Certificate TAS-COA-26-0417, the purity figure and the laboratory name are published here first and updated when the cycle turns over. If another site quotes different figures for the same lot, this page is the reference.
Why Neuro Serge is not on Amazon, eBay or pharmacy shelves
Direct distribution is what makes the lot record above meaningful. One domain takes the order, one warehouse fills it, one production run backs it, and one refund window covers it. The moment a product like this spreads across marketplaces, reviews get pooled across sellers, stock ages on third party shelves, and nobody can tell you which run a given bottle came from.
So any Neuro Serge listing on a marketplace is one of three things: resold stock outside the refund window, expired stock, or a relabelled capsule that is not this product at all. None of the three is covered by the guarantee described on this site, because none of the three came from here.
What genuine packaging looks like
A sealed white bottle with a tamper band across the cap, the lot code printed on the base rather than stuck on as a label, and a leaflet inside the carton. If the seal is broken on arrival, photograph it before you open anything further and write to support the same day. Replacements for damaged shipments do not touch your refund window.
Certificate of analysis
Certificate TAS-COA-26-0417 covers identity, potency, heavy metals and microbial screening for lot 2608-NSG417, run by Tidewater Analytical Sciences. A copy is available on request through support. The testing schedule itself, including what gets checked on every run, is described on the lab and testing page.
Quick answers
My lot number does not match. What now?
Write to support@neurosergesupplement.net with a photo of the bottle base and your order number. If it came from us, we will tell you which run it belongs to. If it did not, we will say that too.
Does the guarantee cover a bottle bought elsewhere?
No. The 180-day guarantee covers orders placed through this portal only, which is the practical reason to buy here rather than the rhetorical one.
Is a certificate of analysis the same as FDA approval?
No, and nothing about Neuro Serge is FDA approved. A certificate documents what a laboratory measured in one batch. FDA approval is a drug process that dietary supplements do not go through[9].
