With all due respect, just because something can be done doesn't make it right. One could inject themselves through their pants and get the injection, but that will not save them from issues arriving. Mixing HCG and Tren would not be a good idea, I highly suggest that you do not do this. Take your HCG sub-q by injecting into your fatty layer in your abdomen area, and go intramuscular for your tren.
