As I've said many times before, kimi does do SOMETHING. When you walk around with it enough...you get intense dreams, your legs feel like they are going through 'growth pains' and you get acne. It's like going through puberty...with the added bonus of feeling like walking on jagged rocks. I do believe that it can help produce GH though. Has anyone ever claim to have grown? Yup....but too few.
I tried it...for months on end and I didn't grow at all. Maybe if you were like a kid it puberty it MIGHT do something, but I'd NEVER recommend it to anyone.
