Zooka, to reach Life Extensions Free T range, your Total T needs to be between 1,000 and 1,250. (2% of Total) Your Free T at 15 with Total T of 700, calculates Free T at 2.15% of total which indicates that your SHBG is in range. Only thing you have to do is to up your dosage of T (assuming you are currently on therapy) and you should have no problem reaching the 20-25 level. Supplements will never get your Total and Free T where it needs to be that I'm aware of. I felt my best when my Free was at 22 and Total T at 1122 or, dead on 2% of Total. I am a high SHBG guy so, I need higher ranges.
