I didn't do it right
I bought this highly-reviewed formulation to try and fix a severe proximal-hamstring tendinopathy, but saw no results after one bottle. Probably though because I was continuing to take ibuprofen for migraines--and ibuprofen is suspected to degrade tendons, which I only recently discovered. So I will try this supplement again after about a year off ibuprofen to see if it helps repair the damage I've done. Big respect for Dragon Herbs. I love all their other products.
