What's going on when we come off a cycle:
Ok, so while we're on the cycle, are natural test production is going down to compensate for the exogeneous test intake, and our production of other steroid hormones (i.e. Estrogen, Cortisol, etc.) is going up to compensate for the heightened test levels. When we come off a cycle, we cease intake of exogeneous testosterone. In other words, we have very low test levels, and very high cortisol and estrogen levels: it's the EXACT OPPOSITE of what we had while starting our cycle.
REMEMBER Le Chatelier's Principle because this is where it gets really important. When we have an excess of one hormone, the others will start shifting around, to attain a certain equilibrium. Ok, I'm gonna say it (and bold it) again because it's just that important. When we have an excess of one hormone, the others will start shifting around, to attain a certain equilibrium.
