i never had, only because i feel i can fuck it up or contaminate it if its legit shit. Pinning for 2 years now and only issue I had was getting some shit in a vain (at least I think thats the only thing that could have happened) because I got sicker then shit and thought I was going to die for three days. The gear was clean because I pinned the same shit after I was sick with no issues. I did not think about it until later, but dr's thought I had ecolli or some major bacteria infection, but every thing was clean in every test and they summed it up to the flu. But I have had the flu before and this shit was not the flu. Go figure it was tren too..
