Well i have always done qv products and have been happy.I lost my old hookup which was through a workout partner.I have been introduced to a new one that only carries ug labs stuff and i am scared of that stuff for some reason.I am not worried about the potency as much as i am about it not being sterile?I worry about infection,hiv,hep,stuff like this.Maybe stupid but i worry.Any help or advice would be great.my email.
