My friend is 20 and still has not hit Puberty that bad?

It is not uncommon for some individuals to experience delayed puberty. While the average age for boys to begin puberty is between 11 and 14, some may not show signs until their late teens or even early twenties. This can be due to a variety of factors, including genetics, health conditions, and nutrition.

If your friend is concerned about their delayed puberty, it is important to discuss this with a healthcare professional, such as a pediatrician or endocrinologist. They can assess your friend's situation and determine if there are any underlying factors that may be causing the delay. If necessary, they can also recommend treatment options to help stimulate puberty and ensure proper development. It's important to be patient and understand that everyone's body develops at its own pace.
