I read his book, which wasn't bad in describing andropause (I imagine most on this board have)... he definitely understands how testosterone deficiency can affect people. But am I remembering correctly that toward the end he started talking about how he likes to administer testosterone if needed - he primarily likes pellets and, (I think) gels/creams are a close second? He has sworn off injectable testosterone and more or less said he won't use it. That's a non-starter for me since I've done the gels/creams. Personally, I have zero interest experimenting with pellets since I know what works now -- I think they start with n-pellets to see how you do, then every 3-4 months adjust number of pellets. I'm done experiementing and honestly it'd be too hard for me to make sure I get back in right on time to get my next set of pellets.
On the Maximus protocol injecting just ahead of half life, I have no issues with ups/downs, which I think is the only medical argument against injection (ignoring people not wanting to do injections, etc).
Not sure I'd pay $600 to have someone tell me to take Human Chorionic Gonadotropin (HCG) and DIM. I tried DIM (the more expensive patented delivery form) for 6-months and saw zero from it.
I know this doesn't really answer your question, but personally I'd save the $600 since it'd cover 3-months of Hormone Replacement Therapy (HRT) for most people.
