Ima 12 yrs old boy and my height is 5'0 and i'm aiming for 6'0 my classmate said that masturbating can help me grow up i tried it but i didn't grew up?

Doubt that but...: A common myth is masturbating stunts growth- i've never heard it touted to improve growth! there's no evidence it affects growth either way. Were you expecting overnite results? The average 12 yo who's 5'0" will wind up about 6'0"-see a growth chart.If you want to exceed that see http://www.Thebodywellusa.Com/blog/dr-mike-carraghers-top-10-ways-to-increase-your-human-growth-hormone-hgh-levels.
