First of all congrats for him starting it! I started with the other form of T but I'm on Nebido too now. It took me 9-10 months to see fat redistribution around the hip/stomach area. Maybe if he goes to the gym it might speed up things. My voice started to change in the first month and body hair started to grow. My facial hair still isn't as visible as I'd like to, being blonde doesn't helps at all. Anyway I've heard there are binders that bind the hips too.
