Riccardo Piana (better known as Rich Piana) was a former bodybuilder and social media star, very well known for his youtube videos often portraying his supermassive supertatooed body. He deceased recently in August 2017. In this video, 2 years ago, he warns kids about the use of growth factors and the damage he suffered.
It is very interesting to listen from a self-experimenter the dranatic deleterious effects of the use of GH, IGF-1 and insulin on organs. Proliferation and growth of muscle tissue and all internal organs, even guts. Everything we already know from teh sceintific literature stands absolutely true in the real world.
