"It's a multi-ingredient herbal powder in capsule form containing black currant extract, lemon powder, and other plant ingredients at unknown individual doses."
Bottom line: This is an overhyped fat-burner supplement with aggressive marketing claims unsupported by clinical evidence, a proprietary blend that hides ingredient doses, and premium pricing for commodity ingredients.
Consumer advice
If you're interested in fat loss, focus on diet and exercise first—they're proven to work. If you want to try a supplement, look for products with transparent ingredient doses and clinical evidence (e.g., caffeine at 100-200mg, green tea extract at 500mg+). This product's proprietary blend and lack of evidence make it a poor choice. The 30-day return policy means you can try it risk-free, but don't expect dramatic results—any weight loss is more likely from the placebo effect or behavioral changes (drinking more water, increased awareness) than the supplement itself."
