It seems like you are very experienced at this. 3 days ago i frontloaded 500mg of enanthate in my thigh. Today, the area feels tight and sore too. Its a little annoying to walk cause theres a little pain. When i touch it, its a little warm but not hot but i didnt get any fever i dis feel a short chill then back to normal. Its My first time to inject in that area. I aspirated and small air bubble came back just to make sure i didnt hit any veins or blood vessel. I can still walk, but there's a stinging pain. A also sanitized the syringe and the vial. Is this noarmal?
