Thank you for clarifying this for me Dr. John. As you may already know, I have started supplementing with DHEA at 25mg/day for now.

Relative to what I see posted on this board, I am taking massive amounts of DHEA.
Any comment, what kind of negative symptoms shoud I watch for.
I also note that at one time LEF was recomending levels of (500-640), and now they are little lower.

Top 10 Most Important Steps For Achieving Ultimate Health
As for DHEA I was mostly taking their 25mg pills, now they have stronger version, 100mg so that is what I take.
Dhea (Dehydroepiandrosterone, Free Base), 25 Mg 100 Capsules
Dhea (Dehydroepiandrosterone) Free Base, 100 Mg 60 Capsules
I will have to check up with them and question quality of their supplies.
From their web site (with their text in bold):
Foundation members are an elite group who are willing to take extraordinary steps to stave off disease,
aging, and death. When members buy products from the Life Extension Buyers Club,
they are assured of pharmaceutical quality and potency.
Pharmaceutical potency means that you are obtaining the actual dose of nutrients used in published studies to demonstrate beneficial results.
Wonder if there may be another reason for my inadequate response to my large DHEA intake?

Do not remember exactly, but I take these high dose of DHEA for at least one whole year. On the day of the test (8AM), I took supplements (including DHEA) after the blood was drawn for the test. The previous day I took most of my DHEA in the morning. So there was about 24 hours between my DHEA intake and blood draw.Originally Posted by Dr. John

To improve absorption DHEA needs to be taken with something oily or fatty. Take DHEA in the morning after breakfast with a tablespoon of olive oil. According to LEF, DHEA labs should be taken 3-4 hours after taking DHEA in the morning.Originally Posted by JanSz

Most supplements I am taking in the morning.
Dhea Complete, 60 Capsules
is taken twice daily and it contain lots of additional supplements that LEF decided are apropriate.
Then is 300mg of DHEA, then also in divided dose I take
Super Omega-3 Epa/Dha With Sesame Lignans & Olive Fruit Extract, 120 Softgels
that may account for the oils and omega-3
I have a problem with taking DHEA and then shortly after get the blood test.
Usually at LabCorp they want me to come early in the morning and no eating or drinking before the blood draw.
Just got monthly LEF magazine for December.
Reading "At home with your hormones" (page 47) got me thinking that I may be low on Pregnenolone.
My Pregnenolone on 10/20/06 was 23 ng/dL (LEF 180)
So I am far from desired level. I started supplementing with 200 mg right after I read my results.
Pregnenolone, 100 Mg 100 Capsules
Pregnenolone converts to DHEA and Progesterone. Both of them can be increased in my case.
Thanks for comments.

I think I remember Dr D posting a study that showed the subsequent conversion to E from DHEA supplementation was fairly low.

We had a little mention on our supplements quality.
Sometimes we have no choice when making purchase.
But if there is a choice we would preffer to go with quality.
I think LEF provides quality products by virtue of their research and advertising.
Once they have shipped to me second batch of supplements requesting that I destroy the one they shipped to me a week before and explaining that their QA discover that the old one were not up to standard.
There is (possibly more formal) way to go about quality.
There is a Good Manufacturing Practices (GMP) certification from the National Nutritional Foods Association (NNFA).
I know that NowFoods have a such certification.

If you know of anybody else, please list it here.

NOW and LEF rank among the best IMO. It's very seldom to hear any complaints about quality about them.
11-07-2006, 07:56 PM
All you need to do is make sure it says "Pharmaceutical Grade" DHEA on the bottle. I use DHEA by "LifeTime", and it is "100% Pharmaceutical Grade" and very cheap and works very well. I only take 25mg per day. I am so surprised you are able to tolerate such a high DHEA dosage. I can only suspect that your absorption is not good.Originally Posted by JanSz

Not really. There can be some significant conversion to 5AD and related metabolites but that is not necessarily estrogenic in the absence of endogenous, pre-existing estrogen. It will actually amplify whatever is already in your system whether it be androgen or estrogen.
I have been criticized before for recommending a 200,100,50 step-down DHEA dose in PCT, but I've done it many a time and it works well to maintain libido and counter elevated cortisol when liver enzymes are still high and adrenal function re-regulates in the weeks post cycle. If you have ever tried it, you know it helps! It is also much more orally active that most people realize too, but 200mg/d or less is OK even for long term use (months). You will generally not encounter suppression or estrogen elevation. I have read studies that the size of the left testicle of rodents can be preferentially stimulated with use of DHEA, still waiting to see that!

Yes, sorry not to clarify 5-androstenediol (5-AD). The majority of endogenous DHEA would normally be biosynthesizes from 17a-OH-preg. DHEA is then mostly converted by 17b-OH-dehydrogenate to 5-AD. Also, trace amounts of androst-4-ene-3,17-dione will be generated from DHEA by the 3b-OH-dehydrogenase and then isomerase pathways, just as trace amounts of 5-AD will be converted to test by those same enzyme systems. Some of these intermediate are prone to aromatize on the 4-ene pathway, but on the 5-ene path (where most of the action is with DHEA) strongly androgenic mixed a/b isomers of the reduced 5a and 5b intermediates will predominate. People say that DHEA is very estrogenic, but that's probably just because that's what they've heard and have never tried it. It is one of the most androgenic hormones I have ever used. I've grown more body hair attributable to DHEA use that anything else over the years. It's an interesting compound and something that I will likely use more and more as I get older. Of course, some may have systems that suppost estrogen formation or expression based of their genes, diet or environement, so this is only my general observation and some may still have probs with DHEA. Very few that I have seen do though even at 250mg/d. Ance is the biggest side at that dose and ~100mg will do for most depending on the specific application.Originally Posted by Dr. John

Wow... If it's that androgenic, I can't help but think that it should have an impact on altering the HPTA. But, if it is estrogenic, I surely do not want to mess with it. It sounds like either way, it's not a good idea to supplement with it.Originally Posted by DR.D
Now; I have mixed feelings on DHEA...
11-11-2006, 12:39 AM
Yeah, you would think so but it's mostly under adrenal control. It is not a testicular hormone. In massive doses, I would think it has to influence HPTA but at the lower doses I mentioned, it must only influence the HPAA if anything because I've never had an issue with it. It's a good supp when applied properly in the right dose.Originally Posted by BigAk

It was studies like that in the mid to late 80's that really got me interested in it too. I read studies that actually demonstrated that fat cells could be converted into muscle cells! That had never been shown to occur before and I forget the mechanism cited but 1600mg/d would make my face break out like a teenager! I can not tolerate over 500mg/d, it's just too androgenic to my skin specifically, but it may be an idiosyncrasy with me alone. If you can tolerate the higher doses, it would be nice for you to share the data.
11-12-2006, 01:05 AM
Isn't DHEA dosing supposed to be spread across the day in 3 or 4 doses? I know I have seen studies that showed that.
What is its half life?
11-12-2006, 02:26 PM
11-12-2006, 03:07 PM
My guess if you take all your DHEA in the morning, that it will have minimum effect on your HPTA because the effects are basically gone before you sleep. I am also guessing that is the least efficient way to take DHEA and that it really needs to be taken 3 or 4 times a day for most effect because of short half-life. I'm just guessing.

As far as testing goes my levels were low noraml taking 25mgs morning and noon my levels are now mid range about 438.Originally Posted by Werewolf

So you are saying taking 25 mgs of DHEA at breakfast and lunch raised your testosterone level by what rough percentage?Originally Posted by pmgamer18
Is there a reason you did not take at Dinner too?
11-12-2006, 04:00 PM
My levels came up over 100% my Dr. told me to take it in the morning and at noon. But there is junk out there I take a good brand.Originally Posted by Werewolf

My wife has been sick for yrs. with Thyroid problems going from Endo to Endo not doing any good. She found a new Dr. that treats with Armour and he did a dam lot of testing on her and found her DHEA was low below normal. She come home with the same brand name her Dr. gave her to take. She was told to take the same dose and now after 2 months she is doing great.

Phil should they test for dhea or dhea-s for accurate readings in serums. MY pregnenolone serum came out to be 10 (0--200). Is it better to use pregnenolone to raise dhea levels or use both at lower dosage. thanks
11-14-2006, 06:29 PM
Test DHEA-S can't say I am just starting on pregnenolone. I am going to do a 10mgs dose starting at once a day after dinner. Then see if my levels come up if not I do 2 a day and so on.

If one has adrenal fatigue (low cortisol) would taking dhea be counter productive since it is antcortical. I am on TRT but dr does not know anything about pregnenolone. At teh health food store there is a transdermal pregnenolone. What is the usualy recommended amount to balance the pathways. I know bioavailabity is the most important thing and orals are 250-30% less bioavialable then creme. I have been takin licorace root for cortisol levels with isocort and I was wondering if this could be cause estrogen levels to rise. Going to get dhea -s, free testosterone, total t, freet t-3, estrodial checked next time to see what is going one. Ever since I stopped the armidex no more morning wood, mental confusion, and decreased exercise tolerance, fat accumulatins an all the fun stuff of estrogen dominace. i need to get this **** balanced. Dr has been very open about things since all others had abandoned me and just prescribed paxil..Go figure
11-14-2006, 10:24 PM
When one has Adrenal Fatigue, usually both cortisol and DHEA are low. DHEA dramatically improved my blood sugar control (hypoglycemia) and energy level after adding it in to my existing regimen of daily hydrocortisone. The synergistic effect of both the hydrocortisone and the DHEA together was much better than the hydrocortisone alone.Originally Posted by hardasnails1973

That was what i was thinking as well, but I never had a dr that was willing to monitor me so unfortunately I never know what dosage to take, plus with having an estrogen problem which is pretty much obvious (lack of morning erection, drop in energy, poor appetite, weight gain, depression) Could taking dhea make it even worse since it converts to estrogen. I found an interesting study where .5 mgs armidex a day for 10 weeks increased testosterone almost 50% after only the second day. Do you think stopping armidex and just taking the testocreme is a good idea just to get a true base line reading. Like I said before my estrodial was 30 with low free and low testosterone so I can only imagine what it is with 10% testosterone. Also found the study show a deficient increase in DHEA with lower estrogen levels.
For pregnenolone 50mgs of transdermal once daily Correct.
What is your opinon of using progesterone if estrogen dominance is indicated or just use the armidex since it is more easily to monitor.

What kind of doses? Like the 1600mg oral doses in that one study? I can't say that I remember ever running across any adverse liver data really. I think 17-ketos are generally very non-toxic due to their ease of metabolism. Sorry it took me so long to get back to you DJ!Originally Posted by Dr. John
11-30-2006, 09:21 AM
Yes. Good point. That is why I have no personal bloodwork to offer in this area! Concurrent use of SERM means you can't get a real estrogen value so who knows. Use of DHEA during PCT is just one of those things you try by chance one time and notice that it worked. Then you try to go back and piece together why it worked. DHEA has good corticometric activity like you say and with or without a suicide AI just works well it seems. I stick to the BID dosing (morning and noon), just because it is a rule not to dose past noon, though only a personal rule and I have no relevant data to validate the significance of early dosing.Originally Posted by Dr. John
