Ok i have done injections before by myself and recently i have been on deca i haev the done the first two shots myself but now im finding the deca wont just wont exert and come thru the tube. I point the needle up to maybe 20 or 30 ml and then enter the needle thru the rubber stopper, put it the bottle upside down , tighten the grip of the deca and the needle the tightest so there is no space and the squeeze as hard as possible, and then pull back to the 20 or 30 ml line but only a little liquid will come out.. Is there something wrong with my bottle? its really getting frustrating and i think it may be leaking too. Im gonna show it to some of my buddies who have more experience with this shit tonight..
