Grenade recently released a tee colorfully supporting their muscle builder, the red themed Grenade AT4. Since it’s unveiling the top has started showing up in retailers, individually or free with the supplement it’s been designed to support. The brand have now revealed another shirt featuring the exact same graphic and text, but in very different colors. Instead of the tee itself being red, the new one is black, with the grenade picture colored green instead of black. If it wasn’t made obvious in the picture or by the description, the top has been put together to support Grenade’s identically colored product, the energizing fat burner Black Ops. Like the AT4 shirt, the follow up is also limited edition, and said to be available free with any purchase of Black Ops. While the tee was only just unveiled, it has actually already gone on sale at the place we last directed you to Tropicana. They haven’t got the deal Grenade are promoting, regardless you can now purchase the Black Ops tee individually, for cheaper than the AT4 original at £17.95.
