I currently have 3 bottles of test cyp, 10 ml and 200mg/ml. I am not going to use all of this becasue i am only doing a 12 week cycle so there will be test left over. My question is, can i sell the remaining to a friend so he can increase his cycle to 12 weeks also or should i not because he could catch something. He is using the same exact stuff, so it should be alright, right? I guess since i used a sterile needle everytime i withdrew test, it shouldnt matter, but just in case... am i right?
