Tab. In GTA5, players can get medical packages by giving gifts to NPC, or they can get medical packages after receiving tasks from Dr. Taylor Crawford in the Car King Change in Los Angeles. There will be some medical kits suspended in the air during the mission. Go to the side of the medical bag and you can recover your blood volume immediately.
