For me, 130mg testosterone cypionate weekly citrulline and arginine with 5 mg cialis daily and 20mg before sex. Also workout daily doing cardio on an airdyne and bands for upper body. All workouts are under 45 minutes and I try to be as non stop as possible, never more than 20 seconds between sets( one of the advantages of band training) And, sex every other day rather than everyday seems to heighten the whole experience. Oh, and don't forget the choice of partner helps...
