100 mgs every three days makes up for a total of 200 mgs per week, and 300 mgs on some weeks, depending on how the days fall - that is just a tiny bit over TRT dosage, and it is not enough for any sort of noticeable results. The worst part is that this tiny dosage is enough for suppression. If you want to feel anything, you should be using about 400-500 mgs per week, or 350 mgs if stacked with some other AAS.
