You are getting some SEVERLY underdosed test my friend.
I just got bloodwork done and I am running 200mg of test-e per week and mine results came back 900 and that was after rumors that the batch of test I had might have been slightly underdosed!
If you are running 500mg of test cyp or e your levels should be anywhere from 2000-3000, there are exceptions body weight and some people might be a little bit below 2000, but def. not 1000, thats cruising levels.
