Trêu chọc cơ bắp & chiều cao

I've just got the results back from a test I sent off for, and it's showing how my body has an ability to gain muscle with barely any effort. That would explain how I gain muscle faster than you, even though you spend hours and hours working out in the gym. I begin teasing you about my muscles compared to yours, I flex and start lifting some weights and within seconds you can see the results. Even with some stretching I gain height too.
