My brother just go an unexpected oppertunity to get a realty good job after being unemployed and or working low paying part time jobs for the last year. He is 34 and about 270 lbs I would guess he is 35% or more body fat right now. The thing he is looking for help with is that he needs to be able to run a mile and half in 15min within the next 4 weeks. He does not do any cardio before this and is generally completely out of shape. I have him running as much as his body will alow him to right now but he is running out of wind, getting cramps, and shin splints. He really needs this job. He's got 4 kids and his wife works part time. I want to know if there is anything compounds that he could be taking right now to help him to archive his goal in just 4 short weeks? And is there any substances that he could take the day of the run to help him through it? He has expressed to me that he feels the reward outweighs the risk on using something to help him get this job within reason. So don't suggest cocaine for him.thanks
