I am an old customer of Xianzhilou, and I have been using their products for many years. The main reason is that there are several products that contain a high content of Ganoderma lucidum, especially Ganoderma lucidum spore oil, which contains more than 30% of the total three. This is relatively rare for Ganoderma lucidum products. After taking this product, my resistance has been significantly enhanced, and my sleep has also been significantly improved. The product is genuine. The store has excellent service. Goods are shipped by SF Express very fast. Cargo packaging mE is very strict. Will continue to repurchase this product in the future.
