Hello, my name is Alex. I am just about to turn 18 years old, 5'6", and 140 lbs. I am wondering if you believe I have the potential to grow at least 2 inches. I have grown about an inch in the last 2 years and never had a big growth spurt. I recently went to the doctor, and having examined that my teticles aren't fully developed and I have little, slow growing facial hair, said that I will most likely grow 2 inches and possibly even enough to reach 5'10". He also said that my penis would grow more aswell (5.5 inches erect). I have full pubic hair, armpit hair, happy trail, and an adult masculine body (broad chest since about 15 and no hair on it). I do five 100 meter sprints 3 times a week, take 500mg niacin (to boost hgh) before bed and 3mg melatonin (better sleep and reduce estrogen) before bed, and do felxible spinal and leg stretches twice a day. I also hang from a bar for 2 minutes before i go to bed for at least 8 hours. I thank you for your response if this isn't a fake
