Part of our Gluco Extend overview. Last checked October 20, 2026.
Gluco Extend at Walmart or Amazon is something we could not confirm: the vendor sells it through ClickBank from its own sales page, and its 180-day refund process asks for a ClickBank Order ID[2]. A bottle bought from a marketplace seller has no such ID, so the vendor's guarantee would not clearly cover it.
Where should you buy Gluco Extend?
Buy Gluco Extend from the vendor's sales page, where ClickBank processes the order. As checked October 20, 2026, the packages are 2 bottles for $158 plus $9.95 shipping, 3 bottles for $207, and 6 bottles for $294, with free US shipping on the larger two[1].
That route gives you three things a third-party listing may not: the 180-day return window ClickBank shows at checkout, order support at 1-800-390-6035[3], and a card charge you can trace, shown as CLKBANK*gluco2bottle, gluco3bottle or gluco6bottle.

Can you buy Gluco Extend on Amazon or Walmart?
We do not know, and we will not guess. In this check we read the vendor's pages and ran the ClickBank checkout. We did not search Amazon, Walmart, eBay or other marketplaces for Gluco Extend listings, so their status is NOT checked.
Here is what the vendor's own pages say about where it sells. The sales page, support page and shipping page all route orders through ClickBank, and the refund steps refer only to ClickBank orders[1][2]. None of those pages names Amazon, Walmart or a retail store as a seller.
The vendor also publishes no manufacturer name, only a footer that reads "Revaslim" and a returns address in Aurora, Colorado[2]. That leaves no brand owner you could ask to confirm whether a store listing is genuine.
If you do find a listing, treat it as an unknown seller until it proves otherwise. Several sites also copy the Gluco Extend sales page with a different ingredient list, which makes it harder to tell which product a listing is for.
Why does the seller matter?
The seller decides whether you get the current product, stored properly, with a refund you can claim. With a supplement that has no published label, those points matter more than usual.
Authenticity
The vendor publishes no Supplement Facts panel[1]. Without one, you cannot compare a marketplace bottle against a known label, so you cannot tell a reseller's bottle from a lookalike.
Storage
Capsules kept in a hot warehouse or a car can degrade, and you cannot see how a reseller stored them. A direct order ships from the vendor's fulfillment network.
Refund eligibility
The 180-day refund asks for a ClickBank Order ID and the return of all bottles to Aurora, Colorado[2]. A marketplace order would fall under that store's own policy instead.
Current formula
Copycat pages list ingredients such as bitter melon, cinnamon and banaba that the vendor does not name. A reseller may be selling a different product under a similar name. Our Gluco Extend ingredients page lists what the vendor names.
How do you verify a seller before paying?
Four checks take a few minutes and catch most problems.
1. Check the checkout
The vendor's order form is run by ClickBank. If the payment page is a different processor, you are not on the vendor's checkout.
2. Check the price
Vendor prices are $158, $207 and $294 for 2, 3 and 6 bottles, checked October 20, 2026. A single bottle, which the vendor does not sell, or a far lower price is a sign of a different seller.
3. Check the refund terms
The vendor gives 180 days. If the terms differ, the guarantee is not the vendor's.
4. Check the contact details
ClickBank support is 1-800-390-6035. The returns address is 19655 E 35th Dr #100, Aurora, CO 80011[2].
Red flags with unknown sellers
Walk away from a Gluco Extend listing that shows any of these:
- Single bottles, when the vendor sells only 2, 3 or 6
- A price far below $49 a bottle, the vendor's lowest
- An ingredient list that differs from the vendor's 6 named ingredients
- A broken seal, missing lot number or no expiry date
- No return address or refund window stated
- Payment by gift card, wire or a payment app
- Promises that it replaces diabetes medicine
Any supplement that names berberine and gymnema can add to the effect of diabetes drugs[4], so talk to your doctor before you start, wherever you buy it.
What should you save after ordering?
Keep these until your 180 days have passed. They are what a refund or a dispute will need, and the refund note must list your Order ID, name, address, email and phone[2].
- The ClickBank receipt email with your Order ID
- The card statement line, CLKBANK*gluco plus the package name
- The shipping tracking number and delivery date
- A photo of the bottle label, lot number and expiry date
- Proof of postage and tracking for any return, since the parcel must arrive within 180 days
Buyer takeaway
We could not confirm Gluco Extend on Amazon or Walmart, and the vendor names neither. Buying through the vendor's ClickBank checkout is the only route where the 180-day refund terms clearly apply. Before you order, ask for the Supplement Facts label, and read our Gluco Extend legitimacy check.

Frequently asked questions
Is Gluco Extend sold in stores like Walgreens or CVS?
The vendor names no retail store. Its pages route every order through ClickBank, and we did not check pharmacy shelves or websites. If you see it in a store, compare the label and price with the vendor page first.
Can I buy one bottle of Gluco Extend?
Not from the vendor. As checked October 20, 2026, the smallest package is 2 bottles for $158 plus $9.95 shipping. A single-bottle listing elsewhere comes from a different seller and may not carry the 180-day refund.
Does Gluco Extend ship outside the US?
Yes, according to the shipping page, at $30 per product for international orders. That shipping charge is never refunded, and you also pay return postage if you send the bottles back.
How long does Gluco Extend take to arrive?
The vendor gives two answers: 7 to 10 days in the FAQ and 5 to 7 days on the shipping page. Keep your tracking number, since the refund clock starts at purchase, not delivery.
Where is Gluco Extend made?
The vendor says it is manufactured in the USA from foreign and domestic ingredients but names no manufacturer. Returns go to a fulfillment center in Aurora, Colorado, and the footer names Revaslim, with no other company details.
