Chestbrah (I lol every time I read that name btw) looks bigger/better than zyzz in many of his solo pics, but when they are standing together Zyzz usually looks bigger - although i've only seen a few of them standing together.
He got bigger after his bro died.
Said always had a great chest, hence the name. He said they were using insulin too. They always stay lean and use relatively low doses of everything. And when they bulk, they never get past 10% bf or compromise their aesthetics.
This is how gym rats need to use PEDs. Small, consistent doses, not getting fat or delusional (see: permabulkers). If you're not competing for anything other than primo vaginas then there's no need to do it any other way. People laughed at these kids because they were faggy twinks, but now they're fuarkin' juicy faggy twinks that pull in mad pussy and even make money. I'd say the last laugh is theirs (minus Zyzz. RIP).
