never mind...
so, an anti-wasting drug basically stops the body from dismantling muscle when we stop using it (yes, i'm more or less quoting from the article atm)
the aim of the drug is to tackle weakness in the sick and elderly, and to help astronauts during their time in outer-space.
so, the 'disadvantage' would be that athletes could pick these up and use them to prevent any muscle atrophy, maybe in between competitions and tournaments, maybe to compete better.
the advantage that i can see is that people who really suffer from either atrophy or dystrophy will benefit from this drug. they will be able to retain their muscles, or at least some of their muscles, say, after breaking a leg, or in the midst of a disease that causes dystrophy, etc.
i'll leave the answer like this, okay? frankly, i'm not too confident about the question, so i don't want to think too much on it. hope nobody minds...i've been hoping a lot lately, eh?
and i'm talking to myself right now :p
