Geesh.....I know whatcha mean bro. Myself, I found that sucking up a little
B-12 into the syringe helps A LOT ! I would throw in (1/2 - 1 cc), B-12 for every (1) cc of Susp. Try that; and another thing that seemed to help was administration into the delts / Tri's! For some reason it wasn't quite as painful as glute or thigh Imjections! Hope this helps some.
