Honestly, how much of a difference did 20-30 iu's make compared to 10 for example.In my 50's I plan to be pure maintenance and longevity, I'd be somewhere between 2 and 5iu's
Under 50, as much as I can afford/tolerate. I'm new to high dose but I ran 20 to 30iu for 5 months recently, also had a previous five week 15iu a day bout with opti's that was probly the most miserable time of my life. It's amazing how much more I can tolerate when I don't have to work and use my hands all day, oh, also when tapering up the dose as sides dissipate.
