Hello guys,
I want to make a thread to clear everything about all the myths on Dutasteride, so no one is asking the same questions over and over again.
Im not gonna mention basic things like what is Dutasteride, side effects, etc because thats basic knowledge you can get from chatgpt.
Here specifically, i want to talk about 2,5mg Dutasteride and how you should ideally take it.
People mention taking the raw powder, 5x 0,5mg Avodart capsules or Dutasteride tablets (hard capsules).
Personally, i used 20mg of Dutasteride powder combined with MCT Oil for a few months to get to 96% of Scalp DHT suppression.
Now im back taking 5x 0,5mg Avodart capsules and getting around 80% real scalp DHT suppression.
A lot of other people take the powder as well, to safe money and to get up to higher dosages (5mg+).
Taking Dutasteride powder is not an option, i explain why:
Those who take raw Dutasteride powder ingest it with MCT Oil because according to research it should be the same as the Avodart and with that be almost identical.
Hear me out:
MCT oil is NOT the same as the oil that avodart uses and will not even come close to it.
Avodart uses a mono- and diglycerides of caprilic/capric.
„Our“ MCT is made of triglycerides so it has to be broken down by your own body to make mono- and diglycerides.
The mono and diglycerides of caprilic/capric used in Avodart are emulsifiers that help increase bioavailability of dutasteride and also serve as solvent.
MCT oil won’t emulsify and has very low solubility in dutasteride, so you won’t form nano droplets that are needed for dutasteride absorption since dutasteride is very high lipohilic drug Log P(=6.8).
The pill is fast dissolved in the stomach and the lecithin on the pill + the mono and diglycerides start to emulsify the dutasteride in presence of the stomach acid which is mostly made of water.
When emulsifiers/surfactants get in contact with water, they make micelles which traps the lipophilic drugs, that in other cases it would be non bioavailable to be used by the body
(the body cant metabolize dutasteride if it is not encapsulated with micelles, that is basically why taking the raw powder with water wont work and that is also why taking only oil with it wont work because it will separate from the oil in the stomach in the absence of an emulsifier)
Avodart also uses a co emulsifier that is Lecithin (which is in the capsule that is fast dissolved by GI fluids).
With this combination, Avodart achieves a good emulsification that makes the drug bioavailable.
Avodart doesn’t even have an optimised formulation, so it could definitively be improved.
To resume, if you want to make dutasteride bioavailable, you will need surfactants and cosurfactants that will make dutasteride bioavailable.
Mct will serve as the carrier oil and you will need it in order to the surfactants to form micelles but it wont dissolve the drug properly and wont do much for drug delivery without surtactants.
You can try to buy and use Lecithin like avodart but also a strong synthetic surfactant which is for example tween 80 because dutasteride has trash solubility in mct oil and getting mono and diglycerides is basically impossible to get if your not a chemist or pharmacist, or it is too expensive, so we have to rely on very potent synthetic surfactant such as tween 80 to solubilize most of the dutasteride with the help on lecithin ofc.
And this my friends is most likely impossible or not worth it.
I know people probably won’t read this shit but i also want to explain on my statements.
So please don’t use the raw powder and skip doing your own capsules.
What to do instead?
My recommendations:
0,5mg Avodart (~50% Scalp DHT suppression) + RU58841
2,5mg Avodart(~79% Scalp DHT suppression) + optional RU58841
Dutasteride Tablets from China/India (3,3mg) + RU58841
Obv 5x 0,5 Avodart can be pricey. But if you can afford it and have a source, go for it!
General advice: Combine x dosage of Dutasteride with RU58841 to never worry about hair loss again.
Few words to these „Dutasteride tablets“:
The normal soft-gel capsule Avodart has higher (obv) and more reliable systemic exposure than standard tablets or hard capsules. Tablets had ~ 70–80% of soft-gel bioavailability in the study below
https://pubmed.ncbi.nlm.nih.gov/27356530/
So it would be the best to take the equivalent of this tablets (around 3,3mg) and i would say optimally with a fatty meal.
And just to quote my last comment to finish the whole Dutasteride tablet topic
„These called „Dutasteride Tablets“ are not just pressed raw powder. They don’t have that Oil inside like Avodart, but contain certain lipohilic carriers and binding agents which help the absorption process. They are not optimal, like the things inside Avodart, but still are important for the absorption process“
Thanks for reading, it took me quite a bit of time to write everything down. Also i read about all of this in german so the translation might not be 1to1 but i gave my best.
And of course im always open for discussions on that topic!
