Slim Michael “I’m Killin’ It on GLP-1” Shaka Wear Max Heavyweight Halloween Tee

Slim Michael brings classic Halloween energy into the GLP-1 era with a dark, retro-horror graphic built around one line: “I’m Killin’ It on GLP-1.”

The design features a masked slasher-style figure walking through a moonlit neighborhood with pumpkins, autumn leaves, and deep orange-and-purple Halloween tones. The joke lands immediately, but the artwork is detailed enough to feel like a real vintage horror tee rather than a novelty shirt.

It is printed on the Shaka Wear Max Heavyweight Tee, so the garment carries as much presence as the graphic. Made from 100% USA cotton with a substantial 7.5 oz / 245–255 GSM weight, the shirt has the oversized, relaxed 90s streetwear fit that gives large artwork the room it needs.

The heavyweight construction includes a slight drop shoulder, forward-thrust shoulder seams, shoulder-to-shoulder neck tape, a 1" stretch-proof collar, double-needle stitching at the neck, sleeves, and hem, and a quarter-turned body to reduce center creasing. The result is a soft, roomy, structured tee that feels substantial in hand and wears well beyond Halloween.
