I have been on TRT for 6 months through a clinic. I decided to escape the clinic for a cheaper alternative. My SubQ injections have never bothered me until switching to a reliable Grey Market source. I have a golf ball or larger lump that is hard and irritated even 5 days post injection. It is 250mg/ml MCT Test Cyp. Am I allergic to MCT? I inject EOD at .2ml.

What are some signs of infection?

If photos are allowed I will follow up with those in the comments. Thanks for the help.
