I am really happy with the GlycanAid HA. I used it after right after my dog recovered from her cruciate ligament surgery thanks to a promotional coupon you sent me. After we were done with the bottle I put her on her regular glucosamine supplement pills and my husband and I noticed right away that she was waking up stiff and was stiff after sitting down for a while. We’ve got her back on the GlycanAid HA for a couple of weeks now and the difference is really noticeable. Thanks for checking in.
