My 47 yr old husband is 6'4", wt 325 lbs. His Dr. has gradually increased his dosage to 7 pumps. The 1st two weeks @ 7 pumps there was improvement, but now it's back to decrease in sex drive, size etc... Due to his overall size, could 7 pumps not be enough, would 8-10 be considered an overdose? His last T count was 240 after the 7 pump increase. He was an incredible lover & I want that part of our life back.
