Cortisol is not all bad. It's all so complicated

I have a feeling extra synthetic cortisol might be a good idea sometimes on cycle. But too
lazy to hunt down some hydrocortisone tabs.
Tren can fuck up mood, making you very depressed and "dark". Tren can antagonize cortisol
real well and I've wondered if this is part of why. Tren can also make you crave carbs like crazy.
Steroids can first increase cortisol and then lower it (studies on pubmed on Dianabol doing this). The Russians had a test for showing if athletes were abusing too many steroids and/or not being receptive (time for a break). They gave a dose of Dianabol and then looked at cortisol. No increase in cort = time for a break.
