Bad Gh testing

[Realpha]

Hey guys, so I bought some generic china hgh. 24iu blue caps. Myself and 2 others had local reactions to the subq injections. Red hot bumps that show up after 24 hours and last 3-4 days. I wanted to know what testing should be done in order to see what’s wrong with this gh? I’ve never tested anything before through Jano so not exactly sure. Ordered through vendor plenty of times before and never had this problem.
