It definitely brings test levels up, you just need to dose it quite often.. I think 12 pills at 40mg each per day does very good.. Every 4 hours or so, though.. Still, it's probably a lesser evil for those who don't want to inject...
I was prescribed it in the UK under the name Restandol.
The maximum dose was 6 40mg tablets not 12.
After a week on it my testosterone level from a morning test was 250ng/dl as opposed to 830ng/dl on Androgel.
I felt awful on it.
I have seen the graphs which show its typical effect in patients. Basically it has a very short half life, a sharp upward surge to its peak within three to four hours and then an equally steep drop off. Basically testosterone levels are never stable with it.
One top TRT doc I saw said it was more appropriate in old men with mild hypogonadism.
As for it being ok on the liver...I have liver problems and I had pain in my liver on them, so I don't personally buy into it not having to go via the liver one way or another even if it is supposed to pass through the lymph drainage system.
I think its problems stem from the fact it is oral. Testosterone undecanoate is used in a drug called Nebido which whilst not exactly great seems to work better..
Someone mentiioned dosing problems, this is true. I was told and read info regarding the need to digest some fat along with Restandol in order for it to be absobed properly. Studies have shown that there were substantial differences in absobtion based on taking on an empty stomach as opposed to being taken with food.
Just my experience...other people may think differently.
