Let's be realistic, if he cycles Clen properly and responsibly I can't see why he'd be damaged unless genetically predisposed to issues. At least 3 people I know who have used albuterol didn't yield the same effects as Clen for pre contest preparation.. typically swapping over to the stronger supp. (I haven't tried it so I'm not saying it sucks)
If he's not competing and using it just for cosmetic purposes I say go with albuterol. Mild.
