my partner is having bad injection pains from his prop/tren cycle and wants to stop after only having done 2 shots, shots consist of 150 prop/150tren eod. I know you can mix b-12 but its already a 2.5 cc shot sho at that point probably better to seperate into two shots right? also any good places to get injectable b-12? i searched and found lots of vet places are those as clean as human grade? and if he chooses to stop will he need to do post after the two or three shots that he has done. thanks.
