a dark and ominous 3D logo for a pharmacy, diabetes, health, and fitness channel. Design the central symbol as a sinister-looking syringe, with sharp, menacing needles and a foreboding presence. Surround the syringe with twisted vines and thorny branches, symbolizing the potential dangers and risks associated with medications. Use a color scheme dominated by deep reds, purples, and blacks, enhancing the sinister vibe. Employ dramatic lighting techniques, casting eerie shadows and creating a sense of mystery. Render the logo with a gritty and weathered texture, giving it an aged and worn-out appearance.
