Looks like dehydroretinol synthesized in a lab is way too fucking expensive.
And the only product so far I've found that has dehydroretinol without contamination from other forms of vitamin A (beta-carotene, Retinyl palmitate, etc) in them is some kind of make-up. And I'm not about to try to eat that.
I did find out that anhydrolutein converts into dehydroretinal in mamals, but searches for that were even more futile.
So, I've followed up every lead, scoured one end of the internet to the other, poured over research documents and this is all I came up with:
>Materials. 3-Dehydroretinal was prepared from the liver oil of the Indian freshwaterfish Wallago attu (Balasundaram, Cama, Sundaresan & Varma, 1956). The livers were homogenized in a Waring Blendor and extracted repeatedly with light petroleum (b.p. 40-60°)-ether mixture. The extract was dried over anhydrous Na2SO4, filtered and reduced in volume. The concentrate was kept at - 300 overnight and the precipitated sterols were removed by filtration at -30°. The filtrate after reduction in volume in vacuo was saponified with ethanolic KOH and oxidized over MnO2 (Camaet al. 1952a). 3-Dehydroretinal was separated by chromatography on a water-deactivated alumina column. The crystalline material obtained after four crystallizations had E1% 1431 at 385m,.u in light petroleum. Oral feeding. The compound was dissolved just before use in refined deodorized groundnut oil containing 50% (w/w) of a-tocopherol.
Tl;dr - It can't be done. At least, not by me.
Sorry /x/, I have failed.

Another update
Might not need dehydroretinol after all, apparently some caroteniods convert to forms of Vitamin A in the intestines.
Seems, in fresh water fish Lutein converts dehydroretinol, but I can't find anything on this in humans.
Needs more research, but at least I have something useful to work with now.

An update.
18 July 2009 - The chemical company I was planning on ordering the Vitamin A2 from still hasn't gotten back to me.
I found a type of baby formula that contains Vitamin A2. But looks like there are some forms of Vitamin A in it as well, Beta Carotene and Vitamin A Palmitate. Not sure if this makes it completely useless to me or not, but it's better than nothing, right?
At least I now have some good leads on where to search in the future.

So, here now that that's all out of the way... Here we go.
13 July, 2009 - Checked local stores and GNC for Vitamin A2 supplements. It seems because it only has 1/3rd the biological activity of Vitamin A, it's not very popular.
14 July, 2009 - Scoured the internet searching a company that offers Vitamin A2, or possibly custom vitamin supplements, found nothing. I received consult from a chemist, and found a website for the purchase of chemicals, unfortunately they might require company backing on orders. I've decided to try, at least.
15 July, 2009 - Still in the process of acquiring Vitamin A2.

Possible perils
Anyway, like any human experimentation, there are things that could go wrong.
If I don't get the dosage of 3,4-dehyroretinol correct, I could suffer from hypervitaminosis. I've looked at this condition... Not appealing, in the least.
Also, the chemical company that is providing it, may not provide it in a form safe for human consumption. I'll be sure to thoroughly check this before doing anything.
Anyway, going to consult a Dietician before proceeding into the experiment. Right now things are just in the planned phase.
Also, disclaimer: Because of possible dangers, I'm withholding where I am buying this chemical. Anyone with half a brain could probably figure it out. However, I am not responsible for the actions of anyone undertaking anything detailed in this blog. If you want to seriously fuck yourself up go right ahead, but don't blame me when your skin starts peeling off. That's your fault for being a fucking idiot.

What I am doing.
Alright, some time ago, it came to my attention that a small quirk in the biochemistry of the eye allowed us to alter our visible spectrum.
"The following story dramatizes how photopigments determine what one can see. During World War II, the United States Navy wanted its sailors to be able to see infrared signal lights that would be invisible to the enemy. Normally, it is impossible to see infrared radiation because, as pointed out earlier, the wavelengths are too long for human photopigments. In order for humans to see infrared, the spectral sensitivity of some human photopigment would have to be changed. Vision scientists knew that retinal, the derivative of vitamin A, was part of every photopigment molecule and that various forms of vitamin A existed. If the retina could be encouraged to use some alternative form of vitamin A in its manufacture of photopigments, the spectral sensitivity of those photopigments would be abnormal, perhaps extending into infrared radiation. Human volunteers were fed diets rich in an alternative form of vitamin A but deficient in the usual form. Over several months, the volunteers' vision changed, giving them greater sensitivity to light of longer wavelengths. Though the experiment seemed to be working, it was aborted. The development of the "snooperscope," an electronic device for seeing infrared radiation, made continuation of the experiment unnecessary (Rubin and Walls, 1969). Still, the experiment demonstrates that photopigments select what one can see; changing those photopigments would change one's vision."

I've got a nice repose of information on this topic, more links and research will be posted later.
So, I've decided that I'm going to try this Vitamin A2 diet, to see how well it works. So... Some relevant information about myself.
