pac @ 17.... pics.

[Slim the BoxingManiac]

And Mayweather has the disrespect to claim that Pac is a definite roider.

Are you saying these pictures prove anything?

I'd have to guess that your knowledge of PEDs is nonexistant if you are.

The pictures don't prove anything, but they show how thin Manny was and how much he was underfed, which explains how he weighed so little.

It's much more just a jab at Mayweather for being ignorant and making judgements without knowing the facts.

Mayweather claims:

-Manny started his professional boxing career so little and is now much bigger.

Reality is:

-Manny started boxing when he was 16. When Mayweather was 16 years old, he weighed the same as Manny did, and Manny was little and underfed, and Floyd wasn't.
-Floyd has gained more weight and muscle mass than Manny. So it would suggest that Mayweather would have a greater chance of having to take steroids than Manny.

Floyd makes a lot of uneducated statements.

Is there any sort of research that ties head growth with steroid usage at all?

No, not steroids, Growth Hormone like I said if it is abused. Which is the same thing Roach keeps banging on about being undectable so tests are "pointless" - Coincidence?

Has Pac's head really grown all that much? His head probably continued growing a bit since he was 17.
