The future of oral testosterone

So, simply taking testosterone undecanoate in a carrier oil, and swallowing it will at best give you a decent result if using hundreds of miligrams of TU AND the required 30 grams of fat (which is insanely expensive and hard to source, assuming bought on the black market)
You don't need 30 grams of fat. This study used 100mgs of testosterone undecanoate, in 5ml of arachis oil
https://link.springer.com/article/10.1007/BF00605634#citeas
Sure bioavailability is more than doubled when given with a fatty meal: but oral testosterone undecanoate in arachis oil has a 40% bioavailability.
Tesosterone undecanoate is not hard to source at all - it's a mildy popular and an extremely useful ester as it has a half life of almost a month, allowing for very infrequent injections, which is useful if you are going on holiday etc.
Not in the US, but a simple 5 minute search on a big domestic site revealed dozens of test undecanoate products:

Please post any evidence, either in the form of bloodwork or a scientific study, showing that testosterone dissolved in tocopherols indeed has good oral bioavailability.
It is known that dissolving progesterone in tocopherols does lead to a substantial increase in its bioavailability, but that is likely due to progesterone have a higher logP value than testosterone, thus increasing its affinity for chylomicron uptake, and with differences with how the liver handles the two hormones.

@eduardo-crispino Sushi chill brother

I think the study you linked is the one that @haidut used on the old forum to poo poo over TU.
As you can see, the TU in arachis oil only spiked Testosterone in the blood highly when it was given with a fatty breakfast. Otherwise (in the fasting participants) it did not perform better than base testosterone.
I actually think that using testosterone as "free crystals" should also work well if you want to do an oral protocol that is devoid of liver tox. As you can see, only 100 mg of free testosterone elevated even fasting levels by about 350 ng/dL. So, using 300 mg twice a day (maybe once in morning once per workout) should also be performance enhancing.
To be clear, using 600 mg free test base per day is dirty cheap. It is about 50 cents per day!
How much would TU be per day?

@alfredoolivas That is NOT 4-androstenediol. That is 4-DHEA, which is a prohormone to 4-androstenediol. No one dares sell 4-androstenediol on the open market in the U.S after what happened in the early 00's. But my point is that UGLs don't give a damn about the law anyway, so if enough people ask for it, they should be able to sell the real thing (not the B.S 2 step precursor)

Testosterone Undecanoate in Arachis Oil has a 40% bioavailability, and it increased tesostereone by 10 n/mol.
It does spike testosterone. However, when you compare it to the levels when eaten with a fatty meal? Sure it spikes it less.
But it does spike testosterone effectively... as shown with the 40% bioavailability.
Furthermore, a large proportion of people eat a fatty breakfast. So if you eat a fatty breakfast? You can expect 100% bioavailability. So testosterone undecanoate seems like an excellent option, especially for those that eat a high fat diet, which many Americans do.

If you buy 100g of TU from Purple Panda Labs, each gram costs 1.14 dollars.
600mg each day would cost 68 cents a day.
TU has a much longer half life than Test base, so thats why I reccomend it
-
@alfredoolivas Fair point on the TU. I concede that it should work too.
But, the long half life is a double edged sword. What if I specifically want a big peak in the morning and pre workout so that overnight I can recover from any suppression?
For me, though, I would want to just go with the base hormone (testosterone) due to weird interactions that may happen with the esterified hormone not being recognized by the body and because if I want to dose it multiple times per day, I may not do it with a fatty meal (like pre-workout)
What I really want, however, is for 1-A-DIOL (1-AD) to come back to the market.
In time there is life but no knowledge; outside time there is knowledge but no life
-
@jamezb46 Does 1-AD turn into 1-testosterone and does it turn into to 1-dihydrotestosterone (dihydroboldenoe)? Any reason why the double bond on carbon 1 is better than carbon 4?
Glucocorticoids thhat have the added unsaturation between carbon 1 and 2, bind to higher affinities to the GR, but androstane steroids have a very low affinity for the GR, regardless of their unsaturation; they exert their anti-catabolic effects via genomic changes from activating the AR. So I assume thats not why you want the unsaturation of carbon 1.
-
@jamezb46 btw, I finished by bottle of tren. I don't see anything very special about it, after running 100mg a week subcutaneously for a month. I don't think I will be buying it again. Apart from turinabol, are there any other (available) AAS I should look into or perhaps you are interested in?
-
It turns into 1-testosterone, which is DHB. The androgen with the normal 4,5 delta bond AND the 1,2 delta bond is boldenone.
Steroids with the 1-2 double bond are thought to be more anabolic than steroids without the 1-2 double bond. I don't know if that is because they bind better to the AR or if they are more anti-catabolic by stopping glucocorticoid induced catabolism or if they work through some other means.
-
@jamezb46 very interesting - it can turn into dihydroboldenone without being 5 alpha reduced ?
-
1-AD is saturated at the 4-5 position so it is already "5 alpha reduced". All that it needs to turn into DHB is for the alcohol on position 3 beta to be oxidized to a ketone.
1-AD
DHB
-
@jamezb46 Very interesting, thank you! I am learning a lot; 5 alpha reduction is the simple removal of the carbon 4 double bond; the addition of the extra hydrogen that is bonded to the carbon, simply occurs because the carbon isn't sharing 2 electrons to the other carbon atom anymore, so a hydrogen shares its electrons to give the carbon a full valence shell.
So a dihydro-steroid is simply a steroid that is missing it's double bond on carbon 4 and therefore has an extra hydrogen. I guess the conversion of 1-AD to 1-testosterone is exactly the same as the conversion 3alpha androstanediol into dihydrotestosterone.
-
Almost the same. Technically 3 alpha androstanediol (if it ever is converted back to DHT) would have to do so through 3 alpha HSD. But 3 alpha HSD is not very active as an oxidant, it usually only reduces DHT to 3 alpha androstanediol.
Since 1-androstenediol has the hydroxyl on 3 at the beta position, 3 beta-HSD coverts it to DHB, and that happens much more readily.
BTW: Since you asked about compounds to try, I think 11-keto testosterone should be interesting. It cannot aromatize, is equipotent to testosterone as an androgen, and has anti-cortisol effects due to the ketone on 11. Sounds like winstrol w/o the liver tox
-
In this video, Haidut claims (in technical details) that mixing androgens with saturated fats like ghee or egg yolks helps a lot with effective absorption https://youtu.be/lfdNtcc0P4I
-
Thanks for the link. Egg yolks may have a unique mechanism because of their phospholipids. So, perhaps mixing micronized testosterone with egg yolks would help with absorption.
However, in the study @alfredoolivas posted, it seemed that blood levels of testosterone after oral administration of free crystals at 100mg were largely unaffected by a high-fat breakfast.
That is to say, blood levels of testosterone following a 100 mg oral dose of testosterone as free crystals rose just as high when fasting as they did after a high fat meal.

Sounds like any amount raising your total Testosterone to more than 4 milligrams a day is likely to turn into estrogen:

… A healthy young man produces about 4 mg of testosterone and 12 to 15 mg of DHEA per day, so 80 mg per week [of testosterone] seems hugely excessive. An excess of either is likely to be turned into estrogen. Pure pregnenolone would be better, but I don’t know of a current product that I would trust to be free of estrogens. HCG isn’t safe." -
@jamezb46 said in The future of oral testosterone:
Why not just create your own cortinon-like product? 3:1:.5 Progesterone:DHEA:Testosterone raws dissolved in ethanol is extremely easy to do, shutdown never occurs due to the progesterone and the androgens are able to be used way more effectively due to less circulating estrogens
