Opinions are different from person to person, but IMO you should start with a low dose to see how your body deals with the gear. Either you choose sus250, test enan ot other test ester, start with 250mg or up the dose to 500mg, but remember that gear is not the only thing (you need to eat, eat, eat, and sleep at least 8h a night for your body to recover). If you decide to go with 500mg a week it´s better to use Liquidex along with it...... since it´s your first cycle you don´t know how prone you are to get gyno.
