N2guard was developed to be a complete liver and organ aid for people running harsh oral steroids. If aren't using any liver toxic oral steroids and are just running a TRT dosage of testosterone, you don't need to take the full recommended dosage.
If you are using liver toxic oral steroids - run the recommended dosage of 7 capsules/day
If you are not using liver toxic oral steroids - use 3-4 capsules/day
If you are not using orals, then you can get away with 4 caps per day.
N2Guard is a nice supplement to have year round, doesnt matter whether you run orals or not. It keeps liver healthy, as well as cholesterol levels in check as well.
