Haha, Yes they do.
When I entered High School we had two separate kids come in from Oklahoma. Both were taking steroids and you could see it. They were 14 years old in the 9th grade and looked like they should have been a Senior. IN FACT...they were bigger than all the seniors. Everyone was coming up to them wanting some gear. The one thing all these guys that juiced early on had in common...THEY WERE SHORT....EXTREMELY SHORT. They all looked like they could have shopped at Oshkosh b'gosh. (Are you getting the picture, Lee Priest short)
Another point is these kids were dumb as a box of rocks too. They were so occupied with lifting they did poorly in their academics. If you give any 12, 13, 14 year old steroids, they're skinny and put them in the gym lifting weights 3 days a week, they're going to grow.
Not Genetics...just better living through chemistry.
STAY POSITIVE!!!!!!!!!!!!!!!!!!!!!
When I was 19, I met with a teenage bbing champ, he was 5' 10" and 220 pounds, nothing too special.
I asked about his weird nipples, he said he had bad gyno and had a correctional operation.
I asked when he started juicing, he said 13...
He was a husky fellow, but nothing special...
He was nowhere benching 4 plates.
So everybody is different I guess.
