I made my own. Was VERY worried about it containing too much bacteria(getting a abscess). But I never did. Made it at 100mg/ml. EOD and worked fantastic. Anytime you make it at home in a non lab(super sterile) enviroment you run a risk of an infection. But then again, many UG labs are no better. My advice is to half a cc to see if you get an infection. If not, your probably good to go. Thats how I rolled the dice. Some pain and that charlie horse feeling was normal for me at Injection site. Til I got used to that feeling I was super nervous I was getting an abscess. For me Tren is phenomenal. Next to Test is by far my favorite.
