i know this is an old forum but just for people searching it up like i did. i have been running sustanon 500mg a week split dosage for 5 weeks now and did my last shot 2 days ago. i went under anesthesia today for surgery and had no complications whatsoever, told my anesthesiest (which i was very nervous about having surgery delayed) and he said it would be fine. just wanted to post it so people in same situation would have piece of mind
