I'm interested in trying an prohormone called Invasion(5a-etioallocholan[2,3-c] furazan-17b-tetrahydropyranol). Yes i know it is more of a mild supplement and more for lean muscle gain and to cut body fat. I've got the prohormone and the liver support but not gonna start till i have everything i need. What would be best PTC? also should i take Formastane and some kind of estrogen killer or anything else?
