As promised, I have my bloods back from running Astro's Test E at 500mg/wk. I was EXACTLY at 4 weeks and 1 day when I took this blood test. The golden rule for mg:test is around 1:10, so at peak, I should be at 5000ish ng/dl.
Currently that blood test read 1986ng/dl. So, I was at 7 pins in when I had this lab taken, and with Test E having a long half-life, this means about 3 weeks of Test E from pinning was in my blood. I would appreciate a True Vet weighing in here, but I think it's safe to say that my Astro Test E is good to go. If I had taken bloods at around week 6, I would expect a number around 4000-5000ng/dl or I'd be disappointed.
