n2guard doesn't have joints covered.. i recommend krill oil and drastically increasing your omega's from foods. if you are not sure what foods have it i have listed it many times you can google.. some off the top of my head are cage free eggs, olive oil, flax oil, salmon oil, oily fish, avocado's. when you eat mexican food always make sure you get tons of guac with it!!
and as has been said lower your dose!! i ran half that dose and my gains were tremendous, you don't need to run crazy dosages and get sides like that because now you are gonna cause a counter productive situation and injure yourself
