ive shot pecs a few times with no problems... what i usually do is .5 cc of prop in each pec so it doesnt immobilize, that happened my first time around... well the last shot in the pecs was 5 days ago and my left pec is fine as usual.. but my right pec is sore as hell and has a lump in it... its no abcess, cause its not hot or nething like that no fever nothing... its from the injection.. i dont think i went in deep enough could that cause the lump to stay for an extended period of time?
