this can and will happen, every cycle will have different outcomes regardless if say user repeats a previous cycle/dosages. For example, a person can run a 12 week cycle and use 500mg test week and have 4000 TT, that does not mean the next cycle will have the exact same outcome he can run 500mg and be at 3200 or 4200 TT as there are several thousand factors that can effect end results everything from stress to diet etc.. thats just how it is biological factors. Heres another example, one person can go to a bar and drink 3 shots and be buzzed. That same person can go to the bar the following week and drink only 2 and be faded or have 5 drinks and feel nothing, the human body and its hormones changes on an hourly basis and keeping everything aligned exactly at all times is literally impossible. This would actually be considered normal
Good point, there's a lot of factors that come into play and no cycle will work out the same. Still however such a big difference in TT with no difference in estradiol is strange imo.
