Arnolds looking big and lean, who gives a shit if he dyes his hair, he has for decades. People slagged him off for not doing enough in bodybuilding, now he's creating more contests and dipping into supplements and he still gets cussed, some people are never happy. He's fucked up along the way but he's also made a life most can only dream about. He just keeps on going, keeping busy and living the dream.
The supplements may fail, may not. One thing though, I think he should have current images used to advertise them, he's in shape and it would be more authentic
