Frequently Asked Questions

Everything you need to know about your reset journey.

No, there are absolutely zero side effects. Both Spiro and Kosen are formulated with 100% natural, plant-based ingredients. They do not contain any laxatives or harsh chemicals, ensuring a safe, gentle, and natural detox and slimming process.

Yes, it is perfectly safe and highly beneficial. Our formulation is plant-based and non-hormonal, making it fully suitable to support your body and wellness during perimenopause and menopause.

You will start feeling the difference in just 7 to 14 days—experiencing less bloating, feeling significantly lighter, and noticing a reduction in sugar and snack cravings!

For a complete and lasting transformation, we highly recommend our 2-month complete treatment course.

No, you will not easily rebound. Unlike quick-fix products, Spiro and Kosen are designed to reset your system from within and help you build an "easier-to-slim" body type (易瘦体质). Once you achieve your target weight, your results are highly sustainable.

It is very easy to incorporate into your daily routine! Take 2 Spiro before bed, and take 2 sachets of Kosen at your heaviest meal. Spiro is chewable or can swallow with water; kosen need to mix/stir with water and take 15-30min before your heaviest meal.

No strict dieting or intense workouts are required! While Spiro and Kosen do the heavy lifting to reset your metabolism, we will also provide you with our exclusive 3+1 Balance Method & Eating Technique Guide to help you achieve faster results while still enjoying your favorite foods.

Yes, both Spiro and Kosen are natural and safe to consume during your menstrual cycle.
