How do you use Mechano Growth Factor?

Heard about spot injection for muscle gain in that body area.Need some help is it worth buying.Don't want to but bunk because now I'm hearing that nobody sells legit MGF or IGF.

about 200mcg post workout. If it's legit it works pretty well. I prefer to just use GH or CJC and Impa.
