Been using axiron for 6 months with 25mg of viagra. 2 pumps total of the solution and my sex drive was reborn. Just recently it feels like my erections are weak (trying to get away from using V pills) and past few times i had success without using the pills. Today wifey wanted a quicky and my penis was not cooperative. Very frustrating to say the least! My diet was poor these past 2 weeks (gained 6lbs) and i was towards the bottom of the barrel of the axiron container. Possible that the past few pumps contained less amount of testosterone? Help!!
