Three "burn" products on BuyGoods look remarkably alike once you read past the branding. Thermo Burn Pro, Evo Slim and RetraBurn are sold by the same storefront, at the same prices, under the same refund policy. This page lays out what each official page says so you can decide whether the differences are real.

Are Thermo Burn Pro, Evo Slim and RetraBurn made by the same company?

The contact, terms and refund pages for all three name North Supplements as the seller, and the refund policies mention the same return-shipping arrangement. Evo Slim's policy lists a fulfillment warehouse in Ogden, Utah. Checkout for all three runs through BuyGoods. We could not find a manufacturer name for any of them in text.

Shared storefronts are common in online supplements. It does not prove the products are identical inside, but it explains why the sales pages read almost word for word alike.

Side-by-side: what each official page states

Prices were taken from the text of each official page in October 2026.

What is the difference between Thermo Burn Pro and Evo Slim?

From the official pages, we could not find one. Both list the same three beta-hydroxybutyrate salts, and both describe BHB as helping the body burn fat instead of carbs. Unless the Supplement Facts panels (shown only as images) differ in amounts, choosing between them comes down to which brand name you prefer or which offer page you landed on.

Our full write-up is in the Thermo Burn Pro review, and it applies equally to the ingredients in Evo Slim.

What is in RetraBurn?

We could not tell. The RetraBurn page calls the product a formula that supports metabolism and appetite but never names its ingredients in text. The FAQ refers to it as "Retra Burn Pro" and recommends using it for at least three months, while the disclaimer mentions following the suggested use for 180 to 210 days. Without an ingredient list you cannot check it against your medications, so we suggest asking the seller for the Supplement Facts before buying.

Do these products contain stimulants?

Thermo Burn Pro and Evo Slim list no caffeine source; BHB salts are not stimulants. RetraBurn's contents are unknown, so its stimulant status is unknown too. Learn how to spot hidden caffeine in our caffeine guide.

Do BHB salts help with weight loss?

Evidence is limited. BHB salts raise blood ketones for a short time, but that is different from ketosis produced by diet. The NIH Office of Dietary Supplements concludes that little is known about whether weight-loss supplements work and that lifestyle change is the foundation (ODS). Our BHB guide explains more.

Is the "thermo" in Thermo Burn Pro misleading?

Thermogenic usually means caffeine, green tea, capsaicin or similar ingredients that briefly raise energy use. None of these appears in Thermo Burn Pro's text. The name is better read as branding than a description of the formula. That is not a safety concern, but it matters if you expected a stimulant effect.

Who should avoid all three?

The mineral salts in BHB products add sodium, calcium and magnesium. People with kidney disease, heart failure, high blood pressure or a sodium-restricted diet should review the label with a doctor. The usual cautions also apply: pregnancy, breastfeeding, under 18, diabetes medicines and other daily prescriptions.

Which one should you choose?

Why do identical products get different names?

Online supplement sellers sometimes run several brand names on the same storefront so each can have its own sales video, ad campaigns and affiliate offers. For buyers, the practical consequence is simple: switching from one of these names to another is unlikely to change your results if the formula is the same. If one did not suit you, look for a product with a genuinely different ingredient list rather than a new label.

How do you claim a refund on these products?

All three refund policies say to contact the seller within 60 days of the shipment date. Since shipping and processing can take more than a week, effectively you have closer to seven weeks of use before the deadline. Keep the bottles and your order number.

Bottom line

Thermo Burn Pro and Evo Slim appear to be the same offer under two names, and RetraBurn shares the storefront and pricing but not a public ingredient list. Pick based on transparency, and do not buy more than one of them expecting different results.
