Save money on MSM / Glucosamine with this simple trick...

So I was looking around for a glucosamine and msm supplement and stumbled upon these guys below... theyre MUCH cheaper than the "human" alternatives but they seem just as pure and they're distilled.. so I bought them and have been using them with great results so far. anyone else do the same?

edit: just realized I cant post the link but the theyre on amazon theyre an equine MSM and glucosamine by "AniMed" a quick search will bring them up
