I am 17 years old and a boy, i have grown 1 cm this month so far, does this mean i am growth spurt and which stage am i on the tanner gstage?

Growing velocity..: Varies with age. Growth spurt usually occurs at puberty. Increment of 1 cm in a month if accurately measured is quite robust. Tanner staging requires a physical examination. A rate of increase of about 6 - 12 cm /12 months is within normal limits. Eat well, be physically active and maintain regular health check up with your doctor to secure optimal growth and development. Take care!
