Introduced test Sustanon (sust) into a virgn muscle on Monday (quad) and my knee and quad have been so swollen since that I can't even walk. Extremely painful. Just a tad bit feverish but not red in any area. This is now Thursday and of course I start to think the worst. Had kinda the same effect before going in the glute but used a smaller dose that time and never had those effects again. Any one ever experience this and what was the outcome
