It will get bigger or smaller with drug use and/or how much you eat. But it's not something like skin that stretches out and when you lose weight it's still there hanging over your belt like a chuck of clay.
Find a pic where a BBer does NOT have that split....including naturals. Look at Shawn Phillips on the cover of Body Of Work, he's got a split that is similar to Dexter Jackson. Mike O'Hearn has than split, Skip LaCour has it. Every single person on earth has that split- again some more than others or some less than others. Drugs only affect the size
to an extent, not whether it's there or not.
