Test E 300mg/ml. I've been doing 1.5 ml in my left ventroglute. Had one shot in the left delt (1 ml.) also result in swelling. Antibiotic ends up reducing the swelling. It doesn't happen every single shot which is interesting.If you could provide further information regarding the product(s) used, injection volume, injection site etc. one could make a more educated guess. Both allergic reactions to a carrier oil as well as abscesses are rare occurences yet make up the vast majority of self-diagnoses.
