ThermaCore Burn review
by ThermaCore Labs
Hides its doses behind a proprietary blend, promises a specific amount of weight loss in a specific number of days, and delivers a caffeine load equivalent to several cups of coffee. Every warning sign in the category, in one bottle.

What we liked and what we didn’t
Strengths
- You will definitely feel something. That is not the same as it working.
Problems
- Proprietary blend conceals the dose of every active ingredient
- Advertises a specific pound figure in a specific timeframe — the classic FTC red flag
- Stacks caffeine with synephrine and yohimbine, a combination with a genuine cardiovascular caution
- Default auto-ship enrolment disclosed only in checkout small print
- Testimonials carry no visible disclosure of whether they were compensated
- No third-party testing or certificate of analysis available on request
Best for
Nobody.
Not for
Anyone at all, and emphatically anyone with high blood pressure, a heart condition, an anxiety disorder, or who is pregnant.
What the evidence actually shows
No credible evidence supports the claimed outcome. Synephrine combined with caffeine has been associated with elevated blood pressure and heart rate, and yohimbine carries its own cardiovascular and anxiety cautions. The proprietary blend structure makes independent assessment impossible by design, which is the reason such blends exist.
What a proprietary blend actually hides
A proprietary blend lets a manufacturer list a total weight for a group of ingredients without disclosing how much of each is present. Ingredients are listed in descending order by weight, and nothing more.
In practice this means the impressive-sounding ingredient can be present in trace amounts while cheap filler makes up the bulk. There is no legitimate consumer-facing reason for the structure. It exists to prevent you from evaluating the product.
The specific-number promise
Marketing that names a specific weight loss figure over a specific period is the clearest signal in the category. The FTC has repeatedly identified claims of this shape as ones that cannot be substantiated for over-the-counter products.
When you see a number and a deadline on a supplement bottle, you have learned everything you need to know.
What’s in it
