I'm 2 weeks into a Sustanon cycle right now and drawing with an 18g needle and it seems like every time I draw I always end up leaving some oil in the amp... I can never get it all out... and if I do try to get it all out.. the syringe is filled with air and I can't even pull the plunger up any farther.. and I'm left with less than 1 cc... like 0.75 cc... It makes me wonder if I'm doing something wrong here?
