To the OP:
I think your brother is fine competing naturally, and if he found the right show could do very well. I would STRONGLY suggest he try to find a tested show if he wants to compete naturally. It will help level the playing field much more than a non tested show. There are a lot of guys that still juice and come off right before a tested show, but he has a much better chance at competing at that level, and it will help him get a feel for the stage for the future.
I would tell him to stay away from Clen, and look into some natural supplements to help him along the way. If he is open to the idea, SARMS can be a real game changer for him in his prep,as well, and most contest testing methods can't test for them.
