Hi ScrapperTL and PhDre,
great posts! I just finished a book written by a retiring German endocrinologist who has been scientifically pushing proper DHEA replacement therapy. He basically confirms what you post.
- DHEA has much more benefits than just conversion into
T (mostly for women, what a pity IMHO) and estradiol (mostly for men).
- Also it seems rather safe if you stay within the physiological norm. Decide yourself if you believe age corrected norm values should be applied or not.
Actually the author of the book I read is focusing more on oral application.
So I wonder if there is any research showing that transdermal DHEA really increases T?
Even the paper that ScrapperTL quoted seems to show the opposite:
"...whereas serum testosterone and dihydrotestosterone (DHT) remained unchanged".
Also I kind of miss some basic statistics, not even the number of patients treated is mentioned.
Myself I see DHT increased a lot (high normal) and estrogen raised (back to normal, so no big issue) and estradiol still within normal range, T low normal (age corrected). 25mg/d.
I enjoyed reading this, keep posting!
P.S. nice avatar pic PhDre ;-)

Here is a copy of one the studies I was reading -
Physiological changes in dehydroepiandrosterone are not reflected by serum levels of active androgens and estrogens but of their metabolites: intracrinology.
Labrie F, Belanger A, Cusan L, Candas B.
Medical Research Council Group in Molecular Endocrinology, Centre Hospitalier de l'Universite Laval Research Center, Le Centre Hospitalier Universitaire de Quebec, Canada.
... Serum androstenedione increased by approximately 80%, whereas serum testosterone and dihydrotestosterone (DHT) remained unchanged. In parallel with the changes in serum DHEA, the concentrations of the conjugated metabolites of DHT, namely androsterone glucuronide, androstane-3 alpha,17 beta-diol-G, and ...
ChokingHazard, interestingly enough, I have seen studies that show Androstenedione to have Anabolic properties at the Androgen Receptor level alone,
prior to conversion to the more dominant/target sex hormones.
Also, the study quoted above is a bit mind-bending that androstenedione increased by damn near 80% yet serum testosterone and DHT went relatively unchanged.
Shit like this blows me away and as
Patrick Arnold has stated many times - he has personally seen that a lot of male sex hormone precursors are under constant conversions, going back & forth in a chaotic plus/minus swing of a dance, until they finally meet their final conversion end.
This oddly enough (random) reminds of Bruce Banner battling his anger before eventually becoming the Incredible Hulk.
Want another brain-exploder?
Look up the research on Pregnenalone keeping DHT in-check (preventing it from skyrocketing) while also simultaneously and indirectly increasing Testosterone levels.
At first this seems beneficial, especially since Pregnenalone is a neuro-transmitter booster and great for well being/brain health/productivity, until you realize that the end result of all this is a more feminine physique because of rate limiting DHT.
The body is fucking nuts, I am amazed by guys like Dr. Crisler that can manipulate it like a puppet master.
