was looking for an ideal combination of enhancers. Liked the keto-dhea, slowly ramped up to 25 mg., the full capsule, testing blood pressure along the way. No adverse reactions, and a definite improvement in overall physical tone (strength, weight management, mental state, resistance to cold, free floating lust) so I went in search of a tweak. Found a product sold OTC known as ENADA, a bioactive form of vitamin b-3 known as NADH. Suggested dose 1 tab on empty stomach with water. Took 6. Got a noticable slightly edgy dopaminic buzz, but nothing serious or debilitating. Seems to mesh exceedingly well with the keto-dhea. Curious nuances like vision getting sharper, could read the teeny tiny type on labels and maps. Mind "felt" significantly younger, everything around was sharper, more alive, like I had been transported back to my self when I was 25. Nothing weird, distorted, no paranoia or overstimulation, just kind of a richness and clarity and sense of well being.
  Okey dokey, time for the Researh Department to put it to the test. First thing upon awakening, 20 mg. ENADA (four very small tabs) and 5 mg. of keto-dhea and set up a two hour date with Miss Hurricane.
  Took another 20 mg. of keto as I headed out the door. All these small pockets of depression that hang out in various corners of my mind were gone. Not like being medicated at all. Like the whole brain is one unified, coordinated whole, smoothly processing experience.
  After an hour or so of physical intimacy, we just sort of spontaneously concluded to blow off our business relationship and go do our thing off the clock in the future. Did an existential double take, WTF ?, o.k. why not ? Let's see where this goes.....
  Was it the full moon ? Some perfect synergy of nutrients and circumstances ? Not the foggiest idea, but if this keeps up, its time to chill out with the hobby.....

we were discussing the available ways to have better sex with nutritional or chemical boosters...

candidtates included Viagra... effective for maintaing an erexction but doesn't get to core hormonal or brain parts of a great sex experience...

i.e. having a stiff erection is one thing, feeling the whole sex experience on multiple levels of your being is another thing...

So... another reader suggested Uprima, sold in Europe but not USA... Uprima does for the mesolimibic part of the brain (that controls sexual arousal) what Viagra does for the penis.

your humble correspondent, I, the Research Department, questioned whether one could use a legal and geneally available pro-hormone (doesn't act like a steroid that a bodybuilder would be interested in) could act as a general physical toner for the aging body, and assist in better sexual responses as a side effect.

Keto-dhea is a legal, and from my experience, effective supplemement that helps bring males (women may react differently) back around to how one felt when ones hormones were in abundance, the grass was high, and passionate sex was the order of the day.... how little we appreciated what we had, or youth is wasted on the young...

At his point, 25 mg. of keto-dhea seems a bit on the strongish side, but I'm not sure if I'm adapting to it or should cut back to about 18 mg.

Then I found ENADA, a vitamin based metabolic energiser that is also legal, non-toxic, and generally available. Somewhere between 5 mg. and 20 mg. of ENADA plust the keto-dhea seemed to put me square on the sweet spot of mental and physical functioning.

I suspect this has a lot to do with dopamine and dopaminergic neurons, these contol fine motor coordination, sex drive , motivation, a whole lot of the "get up and go", proactive, take contol of your life type brain functions.

 No matter how stiff your penis is, if your dopaminergic brain cells aren't producing enough or if too many of them have died off, you aren't going to feel sex in any profound way, you probably won't have too much spark to try new things or change your habits, and if you lose enough of them, you start to get all trembly, and if you lose way to many of them, you get Parkinson's disease.

 Stats I read suggest that we lose approximately 13% of our dopaminergic neurons after age 40 (or was it 30 ?) PER DECADE...
which would explain a lot of things. The major problem with dopamine neurons, especially those in the sustantia nigra, is that you don't have too many of them to begin with.... like 30,000 or something...

 I'm guessing that the keto-dhea and the ENADA enriched my dopamine system, which then led to interesting personal outcomes.....

"As far as human beings are concerned, the most important point to clarify is that during the different episodes of sexual life the main gland at work is the brain. In modern biological sciences the brain is primarily a gland-releasing hormones. But only the primitive brain structures which arc around the hypothalamus and which we share with the most primitive mammals, are active. What is particular to human beings is that these brain structures are covered by a highly developed new brain, a neocortex which supports the intellect. When this rational brain is overactive, it tends to inhibit the primitive brain. During the birth process there is a time when the mother behaves as though she is on another planet. She has to change her conscious level and reduce the activity of the neocortex. Inversely during the birth process and any kind of sexual experience, any stimulation of the neocortex tends to have an inhibitory effect: logical words, feeling observed, bright lights, etc. Few couples can make love if they feel observed, or if their neocortex is stimulated by bright lights or logical words."
