Dissapointed
I've been using Glucosamine Sulfate, for my joints,  for years with good results and assume this BS supplement will continue to do the job. I use a lot of BS supplements, and up until now, have been satisfied with the quality of all of them. The 500 gram bag I received was full of hard lumps. So much so that it was impossible to take a accurate 1/4 tsp measure from the bag. I had to empty the bag into a large bowl and go through the tedious process of crushing the lumps to make this glucosamine sulfate usable. Not an impossible task, but tedious at best, and not something a customer should have to deal with. I expected better better quality from Bulk Supplements.<br /><br />11/24/2016- After using this for a 7-10days I am extremely annoyed with having to deal with the lumps, but worse than that, my knees are aching constantly.  Can't recommend this stuff. It seems that I must have received a defective (maybe old) bag of glucosamine sulfate powder. If you can't depend on consistant product quality it is not worth buying no matter how low the price.  Crossing it off my list and going back to Source Naturals Glucosamine Sulfate Powder.
