any frequency less then a week is acceptable, in fact when I take test only I inject 1000 mg in one day, once every week, makes no difference. When I take others stuff like tren or EQ or even both then I take test with every shot of tren or eq so that it adds up to the desired mg/week
I concur.
I usually shoot Test twice a week but due to it's half life once a week is adequate.
