So I tried to find out just how tall Kristine Stavås Skistad is, and my google fu turned up articles back to February 2019 talking about her and Fossesholm being given HGH in childhood. However, these look to be poorly google-translated articles so I'm not sure as to how much there is to them in terms of genuinely significant information; the article focuses more on Fossesholm who apparently was treated with HGH for the purposes of addressing abnormalities of height, in the same manner as Lionel Messi, as at 13 years of age she was just 137,5cm tall - and even today she's pretty small.
However, given Skistad is so tall and rangy and still as powerful as she is, she towers over the opposition, so she would not seem like a candidate for somebody where there is reasonable justification. Skistad's treatments do not include anything outside the WADA code apparently, but it does of course raise that additional question following the fuss about the Norwegian anti-doping federation's rules being non-compliant with WADA because of their rules about testing minors.
