According to this landmark study these are the mean averages of testosterone in healthy men (check out table 2)
The mean avg for 125 mg/wk was 570 ± 75
The mean avg for 300 mg/wk1,345 ± 139
The mean avg for 600 mg/wk 2,370 ± 150
Where you guys are coming up with 2,300ng/dl with only 100mg/wk or even 200mg/wk I don't have a clue.
Also the chart above clearly demonstrates how important the timing is, look at the level at 3 days and then 6 days. It is HALF.
So I'm going against the grain here, and if the OP confirms he waited 6 days after a 425mg injection (250 x 1.7 =425) then I'm going say this gear is no where near as underdosed as everyone is thinking. btw, the true protocol is to do 1 weekly injection, then have blood drawn exactly 7 days later. But, if you inject twice weekly (half the amount of course) then have blood drawn 3.5 days later the result will be very close to the same.
Just so you know both Watson and AY test-e get me right in the 950-1,000ng/dl range with a weekly 200mg injection. A gram of test puts me at slightly over 5,000ng/dl, which falls right in the range this study came up with (interpole 125 and 300 = 213). If 600mg gets one to 2,370, no way 400 more is going to get you to 8,000ng/dl.
I think OP should have this test redone after running a once weekly injection of 600mg/wk for at least 3 weeks.
