I have 20 servings of creatine that expires in april -2016 still sealed ana non opened will it be okey to postpone the usage to the month of july ??

May be: It is not likely to do any harm if you use it in July, however, it will not do any good either. Such supplements are good for lightening your wallet, but have no influence on your health. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
