I am looking into Gongjindan as a gift for my parents, and the more I search, the more I realize I shouldn't just buy it from anywhere. I am specifically looking into the original formula Gongjindan because I heard it is the best. I am being very careful in my search because I heard that the musk content and whether the musk is genuine are the most important factors. A senior colleague at work once took Gongjindan made directly at a Korean medicine clinic and said that they definitely felt less tired and their body felt different. So this time, I have decided to bite the bullet and get something proper. There are some sold at pharmacies, but I have heard many times that the original formula Gongjindan made directly at a clinic is much better. I would trust a place even more if it contains genuine musk and is prepared exactly according to the original formula. My parents have been feeling very weak lately, have trouble sleeping, and say they are tired, so I plan to give it to them as a gift and try taking it myself. It would be better if it were in the Seoul area. If there are any famous Korean medicine clinics that prepare Gongjindan directly, please recommend them. I would like to hear reviews from people who have actually tried it, not just advertisements. Please recommend a Korean medicine clinic where I can purchase the original formula Gongjindan.
