Official website only, with ClickBank running the checkout. That's where the current price, the three bonus guides and the 180-day refund live. It isn't on Amazon or Walmart under either spelling; anything there is a reseller or a fake with no guarantee.
Buy From the Official Website
The manufacturer sells through its own site with ClickBank as the payment processor. That's a good thing for you: ClickBank has been handling refunds for supplements for twenty years and its process doesn't depend on a small company's goodwill. The charge is one-off. We looked for a subscription box at checkout and there isn't one.
Current Pricing & Packages
The 2-pack adds shipping on top of the $158, which pushes the real per-bottle cost above $80. The 3-pack and 6-pack ship free and include the bonuses. If you're planning to follow the manufacturer's three-to-six-month suggestion, the 6-pack is the only one where the arithmetic works. If you're testing the water, the 3-pack is the honest starting point.
Free bonuses with 3 & 6 bottles
Three PDFs come with the 3- and 6-bottle orders: Clear Mind Reset, Focus Rewired and a VIP Wellness Guide. They're habit guides, mostly about sleep, focus routines and general health. Slightly awkwardly for the product, several buyers told us the guides were the most useful part of the order. They're not a reason to buy, but they're not nothing.
There's No Harm in Starting Small
Given how uncertain the benefit is, there's a good argument for not buying six bottles of anything on day one. The 2-pack costs more per bottle and you'll pay shipping, but it's $158 rather than $294, and the refund is the same 180 days. Start small, set a two-month checkpoint, and scale up only if something's actually changed.
Why Not Amazon, Walmart or Stores?
It isn't stocked anywhere else. Any Amazon, Walmart or eBay listing, whether it says Neuro Serge or Neuro Surge, is someone reselling bottles or selling something that looks like them. You lose the refund, you lose the bonuses, and with a product that doesn't print its doses, you'd have no way of telling a counterfeit from the real thing. A price well under the official one isn't a bargain; it's a warning.
Using the 180-Day Guarantee
Every pack gets 180 days. If it hasn't done anything for you, contact the seller's support (the details are in your ClickBank order email) before the window closes, return any unused bottles, and ClickBank processes the refund. Keep the confirmation email; it has the order number you'll need.
Before you order: if you take blood thinners, blood-pressure or diabetes medication, or anything else regularly, ask a pharmacist first. Green tea, grape seed, cinnamon and licorice all have known interactions, and the doses are hidden. If caffeine is a concern, email the seller about the green tea extract before buying.
Bottom Line
Official site, ClickBank checkout, one payment, 180 days to change your mind. Pick the pack that matches how sure you are, which for most people means not the 6-pack on the first order. The full review is where we make the case for and against buying it at all.
