You say Joey Mantia doesn't look juiced but Zac Effron does, lol. You could fit two of Zac's legs in the place of one of Joey's, and the definition is astounding on Mantia.
Is Zac Effron that insecure or needs to get beefy for women? Really? I find that hard to believe. He had a drug and alcohol abuse problem and he went into treatment for it, saying it was destructive and he wanted out. But now he's on PED's to get a great physique?
There are many reasons to juice. Not every kid looks this ripped so it improves his branding or whatever.
Again, it's not just about size. I did a quick google.
Compare. Do you see the difference? Who has more muscle but who looks like he has more androgens in his system?
It is SO obvious, the diffence in the
look.
Joey obviously trains much much harder. Why is he holding considerably more fat? Yes, maybe he simply eats more, but there's more going on here.
