The above photo indicates the injection locations for the pectorals.
You have to inject in 9 locations (3 rows of 3 injections) as indicated in the photo, daily. The idea is to make the muscle ‘lift’ at once. If the entire pectoral muscle is not covered with the injections the pectoral can end up with a lumpy appearance.
25gauge to 30gauge half inch (13mm) to 1 inch (25mm) long needles are adequate.
