[QUOTE="Cataceous, post: 137775, member: 38109"] We did have somebody at the PeakTestosterone forum say he had good agreement between calculated free testosterone and the mass spectrometry-based measurement. But the mass spectrometry tests are complex and easier to mess up, which I've found out the hard way via botched estradiol tests. A more sophisticated free testosterone calculator, such as the spreadsheet you can download [URL='https://anonfile.com/c4C4tco5b8/Free_T_and_E2_calculator_xlsx']here[/URL], takes DHT as an input rather than using a default value. DHT does have the highest binding affinity for SHBG and can displace testosterone as it increases. However, in the usual physiological range the effect isn't so large. But in the DHEA paper DHT increased from 64 ng/dL to 339! [/QUOTE]
