Let me clarify. Obviuosly I know test levels fluctuate up and down based on injection dose and timing. What I'm wondering is if test levels still fluctuate from day to day based on lifestyle as it does with natural test production. With exogenous test, do test levels still spike in the morning/evening, rise and fall based on workouts, fall due to lack of sleep, poor diet, alcohol, etc...? My assumption would be that it doesn't since the exogenous test is there no matter what, but I'm curious if anyone has first hand experience or studies to reference regarding this. Btw, this is just a random curiosity question, not based on anything I plan to do....
