A person who is already in the 99th percentile athletically and at their peak athletic age (early 20's to early 30's) would be silly to take HGH. To the extent that HGH actually improves the performance of professional baseball players, it is pecking at the margins and carrying a disproportionate set of risks that makes it's use as a PED a game of diminishing returns.
You did more than stop taking HGH. You also stopped doing whatever you were doing to effect the change in body composition.
I became a much, much better baseball player when on HGH, then before, and then got worse afterwards. My swing and bat speed was amazingly quicker after taking it. I actually had to adjust my whole hitting approach because I was now pulling everything. It wasn't about being stronger, it was about being quicker and more athletic.
I agree that for professional baseball players, the difference wouldn't be as big, but baseball is game of inches and milliseconds. Every little bit matters. Like I said, it's not the same as with steroids, but it definitely is a performance enhancer.
