Thank you for viewing! This is a KIRIN imuse supplement for immune care and muscle support. My family has been using the "immune care" product for 3 years, and I received this newly released sample. However, since they are already taking the "immune care" product daily, I'm offering this to someone who would like to try it. Although it's a sample, it contains 90 tablets, a 15-day supply, just like the regular product, which retails for 3,980 yen. I'm not sure about this particular item, but my family has been taking the "immune care" product for 3 years and feels it's effective. This is just my personal opinion, but they have a designated intractable disease that weakens the immune system, and with no specific cure or treatment established, they started taking this "immune care" supplement, grasping at straws. To be honest, they haven't felt immediate effects, but they haven't caught a cold at all. They used to get sick easily due to their weakened immune system, so they believe it's working. (This is about the immune care supplement, not the item being sold.) For your reference. Expiration date: August 2025 Shipping will be via Yu-Packet Post. I aim to ship on the same day as purchase. Please feel free to ask any questions in the comments. (﹡´◡`﹡ )
