To semi-support my claim (admitting I'm reaching a bit):
http://press.endocrine.org/doi/full/10.1210/jc.2003-031354
"In conclusion, we have shown that a single administration of 1000 mg TU in
healthy young men, raising circulating T levels into the supraphysiological range, produces detectable but
relatively minor mood changes...Our results suggest that TU, administered in a dose within the range required for male contraception, has only
very limited psychological effects, restricted to short-lived mood changes."
Therefore, if taking my test levels to a supraphysiological range has limited psychological effects, I'd assume doubling my test in the physiological range would have even less of an effect.
