growth is more or less genetically-determined so properly done weight-lifting should not have any adverse effect on linear growth after a young man (? ) has reached puberty. protein powder will not stunt growth but it will also not build muscles or "bulk you up". if not taken properly excess protein can harm your kidneys so be careful. don't believe everything you read on those protein supplement claims.
can lifting weights/weight traning at ages 13-14 stunt growth? . also can taking protein powder also stunt growth? urgent help!
