HIV unlikely: It is highly unlikely that you will get HIV from what you described. If you must, you may get a HIV nucleic acid test in 6 months. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. 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.

No risk: It is exceedingly unlikely that it was used before it was sold, but you could ask the shop if you remain concerned. Even if it was, there is no realistic chance of HIV. Don't worry about it.
