Now I've read many articles on how to use hcg. But I wanted to get others opinions. I've never used it with any cycle but plan on it in the future. I know u do 250ius twice a week. What do u perfer, shooting into ur Muscle or the other way between the fat and muscle on ur stomach? Cause id rather pin in my muscle, So does anyone know if it makes a diffrence? Are both ways just as effective? And what size pin do I use? Thanks for ur help!!
