well gh is a fat burner and its great for the skin, but while on gh your skin is going to look thick because youll be holding some subQ water. gh makes your skin very shiny and smooth.
steroids that would help to give a hardness and density to the muscles, which is essential for that "paper thin skin" look, would be masteron, halotestin, trenbolone, primobolan...and all steroids to some degree...
but the main thing for4 thin skin is body fat, and then after body fat comes water. to shed body fat combine any steroid for muscle retention and imporved fat burning with thyroid for contolling metabolism and with a low calorie/ sufficient protein diet
