wow! 5mg drops your levels by half? that's crazy. maybe that's why at at 30 mg i'm feeling pretty amped up. I tend to feel better in the middle of the road. I'm only on my 3rd shot but i definitely feel it. maybe i should back it down to 25mg.A 25mg EOD protocol would put me well over 900 ng/dL and I'm a low SHBG guy (16-18). If I drop the dosage down to 20mg EOD, levels drop by half. It's definitely not linear.
