We have all experienced sore muscles or pains at one time or another in our daily lives. This Blue Goo Pain relief gel contains emu oil, aloe vera, and MSM. The gel is blue in color and is thick like pudding. I also has a very pleasant odor to it, not offensive like other pain gels. After applying the gel to your ache, you feel a warm, tingling sensation. The product isn't greasy at all and it soaks into your skin quickly. It takes a few minutes before working nut it lasts for at lest an half an hour or more in some instances. My two teen sons use d it for their aches during football season and they ahd super results. I highly recommend this product to anyone who experiences pains and muscle aches. It does a great job of providing relief. You can even use it for those terrible headaches and for arthristis pain relief. The price cannot be beat for such an amazing product!
