I thought this was interesting a number of top athletes have been using American made technology to greatly increase their competitive age. People like Devon Larrett, Dave Chaffee, John Brzenk arm wrestlers have been being treated with various methods including TRT in some cases but more to the point stem cell treatments. I thought that was not very effective but apparently they are not using controversial steam cells but have harvested it from years ago and froze it. Other competitors from Golf, Basketball and other sports have been seeing huge swings in performance. Levan Saginashvili traveled to the US or Canada not sure where he may have received steam cell injections not sure? He has opted out of competition for now and Thor also I believe received them? I am not sure the questions about performance enhancement but Deven looks monstrous compared to other competitions and others like John looks 20 years younger even though he has gray hair they maybe on to something.
