The “fat burner” that promised quick results hid a lethal industrial chemical and a prescription drug inside, federal tests found.
Story Snapshot
- Food and Drug Administration testing found undeclared 2,4-dinitrophenol and fluoxetine in a weight-loss supplement.
- The company issued a nationwide recall of Lipofit Extreme Fat Burner 2.0, lot 25M12F, expiring 09/2027.
- 2,4-dinitrophenol is linked to fatal overheating and has no antidote; it is not legal for human use.
- Weight-loss supplements are frequent targets for hidden drugs and dangerous chemicals.
FDA flags hidden hazards in a popular fat burner
The Food and Drug Administration said Lipofit Extreme Fat Burner 2.0 contained two undeclared ingredients: fluoxetine, a prescription antidepressant, and 2,4-dinitrophenol, an industrial chemical known to cause deadly overheating.
The agency’s lab analysis triggered a nationwide recall by the seller, Ana Salazar Modela Tu Cuerpo Inc., for one lot labeled 25M12F with a September 2027 expiration date. The FDA recall databases list the product and the reason for the recall in matching entries.

The recall notice directs consumers to stop using the product and to dispose of it. It also warns that people with certain conditions, or those taking interacting medicines, face added risk from hidden fluoxetine.
The agency emphasized that 2,4-dinitrophenol is not an approved ingredient in any supplement. The presence of a prescription drug and a toxic chemical without labels removes a shopper’s choice and bypasses medical oversight.
What 2,4-dinitrophenol does to the body
Doctors have documented that 2,4-dinitrophenol drives body temperature up, stresses the heart, and can kill even at small dosing errors. Medical literature reports cases of death tied to this chemical, and experts note there is no known antidote.
Care teams can only support the patient and try to manage the heat and organ damage. Researchers state the substance has been banned for weight loss for decades in the United States and deemed hazardous abroad.
These facts align with the basic duty of care. Selling a product that can overheat a person from the inside is not a gray area. It is reckless. Hidden 2,4-dinitrophenol removes informed consent. The market works only when labels tell the truth and sellers play by the rules that keep people alive.
Why weight-loss pills keep getting caught
The weight-loss aisle is a hotbed for fraud because fast results sell. Studies show hundreds of supplements have contained unapproved drugs over the years, often in products pitched for slimming, sex, or muscle building.
Some brands spike pills with real pharmaceuticals or chemicals to give a strong effect. That shortcut cheats honest firms and puts buyers at risk. The Food and Drug Administration keeps a standing initiative to test and warn about these products.
Recall: Lipofit Extreme 2.0 Fat Burner, lot 25M12F, exp. 09/2027. FDA testing found undeclared fluoxetine in AM tablets and DNP in PM tablets. DNP is not FDA-approved for any use.

Enforcement has teeth when backed by the Department of Justice or when people get hurt, but the smarter path is prevention. Consumers should favor brands that submit to independent testing and share lot numbers, test results, and clear contact details.
Doctors, pharmacists, and coaches should ask patients about supplement use the same way they ask about prescriptions. A simple question can catch a risky bottle before it causes harm.
How to check your cabinet today
Look for Lipofit Extreme Fat Burner 2.0 with lot number 25M12F and an expiration of 09/2027. If you find it, stop using it and follow the recall instructions in the Food and Drug Administration notice. Report side effects or quality issues to the Food and Drug Administration’s MedWatch.
Then scan other weight-loss products you own. If a label makes big promises, hides the full ingredient list, or lacks a real company address, treat it as a red flag.
Policy should back this vigilance with simple, firm steps. First, raise penalties for spiking products with hidden drugs. Second, require clearer lot tracking and make third-party testing visible on labels. Third, speed public alerts through pharmacies, not just agency websites.
