Fat-Burners

The fat burner shelf is the most marketing-heavy corner of this store and the one where the gap between the label and the effect is widest. Almost everything here is a stimulant stack - caffeine, synephrine, yohimbine, green tea extract - dressed up with proprietary blends that hide the doses. That is the first thing to look for, because a blend with the amounts unlisted is a blend that is underdosed by design.

What actually determines results

Deficit, training and sleep decide body composition; a fat burner is at most a nudge on top of that. The compounds with real evidence behind them are the unglamorous ones - caffeine and adequate protein intake. Everything else is a question of tolerance, side effects and whether the manufacturer will tell you what is actually in the bottle.

Buying checks

• Look for a full ingredient list with actual milligram amounts. Proprietary blends are a red flag, not a premium feature.
• Third-party testing, if offered, is worth more than any marketing claim.
• Check the expiry and seal; stimulants degrade.
• Read the ingredient list for anything you are already prescribed or that interacts with medication.

Many of these are restricted in various countries and several will show up in a banned-substance test. If you use them, know what is in them.
