"Andy I know tren clears very quickly compared to eq, but I don't know that that is the only factor to consider. As you hang here listening to hundreds of guys complaining that they are crashing harder when they used tren you will see a pattern. Those that use tren along with eq, and most do, have a harder time recovering than those who use eq with test. I don't know why for sure, I only know that tren is 3 times as anabolic and twice as androgenic as test, so maybe it's just that the harder you get kicked in the testicals the longer it takes to recover."
ULTER, my guess is that it is not the relative androgenicity of trenbolone that is causing the "crash", but the speed by which it is excreted from the system. As ANDY stated, suppression is a given on any cycle of this sort, but with longer acting agents such as boldenone enanthate, the androgen is still in present for a period of time, whereas with tren acetate, you are flying high, then BOOM!!!, rock bottom.
Another consideration is the relative androgenicity on the CNS. Since we know that tren is a potent AR agonist and has considerable effects on the nervous system, we may want to think about psychoactive agents as bridging drugs. People have only been looking at anabolic agents to counter the loss of muscle tissue during a bridge, but maybe also adding something like l-dopa, bromocryptine, adderall, ritalin, etc., may counter the psychological crash, which may hinder any depression that may occur.
