GH lasts for hours because GH isn't the hormone with intrinsic activity...it induces IGF-1 release which has a halflife that is much much longer.
Androgens don't share this characteristic. But I do think there are some "lasting" changes that can occur from strong AR stimulation.
Halflife is important in this case because it's the terminal halflife. This means this is the halflife once the ARs have already been bound and equilibrium is achieved. So I don't think that second part about AR affinity holds true.
Very interesting, I knew that the GH caused muscular IGF-1 production, among other hormonal responses in the body.
After responding earlier I took the time to research it a little bit since I knew there was a cascading effect but not the technical term for it or how exactly it worked but I knew there was a process kicked off protein synthesis at a supernatural level.
As far as the affinity not being a factor, I am not so sure that isn't the case. I am sure you know this info but the action of a steroid binding to the AR is to cross the cell barrier, bind to the AR receptor, once bound move into the nucleus of the cell and signal for (mRNA) production, the mRNA calls for extra proteins to be created IE... extra muscle. That process is called Translation, and it is this process that I
assume continues well after the steroid has bound to the AR. (That is my simplified version of the stuff I was reading)
That is why I was speaking to the affinity for the AR and faster binding is very important considering the half life of TR3ST is very short. If the binding affinity is high then more of the androgen will bind during the short halflife. Once bound the growth is already set in place for however long the Translation process takes. For the product to have such great results for people even with a 40 minute half life they must be getting a lot of binding at the AR.
So what i meant to say originally is not that affinity is more important than halflife, but that the short halflife dictates that maintaining constant levels of TR3ST via oral administration without an ester is impossible without taking a dose ever 20-30 minutes... However the affinity is high enough in this case and the steroid strong enough that it works quite well even though it is only available in the blood stream for a very short period.
That being said with it having short half life I would take it surrounding any anabolic activity and at times when you are fed well. You definitely want fuel for the building. As far as avoiding TR3ST in the evening with a 40 minute halflife there is not really any reason to do that. Just take it maybe an hour or so before bed or whatever. Should be basically out of your system when you go to sleep. At night your body checks the negative feedback loop to see how many androgens you have running around to see if it should make more or not. Since this is so short half life i wouldn't see any reason why it couldn't be dosed in the evening without any negative affects. However bottom line is the TR3ST is gonna shut you down anyway, and you do a lot of your growth while sleeping so why not dose close to bed and have heightened protein synthesis while you sleep.
