The waivers are a common thing in all sports. Waivers are only granted if it is proven that the athlete has a significant deficit in HGH. The amount they are allowed to take is strictly regulated to bring the levels up to a normal range. Thus if true, which it appears it is not, he would not be gaining any advantage over anyone. So I wouldnt have an issue with it because it would be medically necessary not used for performance gains.
