I am just taking a shot here and assuming this is your first cycle.
Where to start?
1) you will need more than 8 amps of test to run a descent cycle.
2) your first test only cycle should be ran at 500mg/week, some will get good results from 250mg/week.
3) Sust is best when shot eod due to the prop, however 2-3 injections per week is also commonly used.
4) You have no mention of PCT. Do you plan on doing a test taper? Probably not since you are already short on test. If not then you better get some nolv or clomid fast.
Usually I would say to not even attempt the previously mentioned cycle however you have already shot 500mg test so you are already on your way. If I were you I would just split the last 6 amps and shoot 125mg 2x a week. This will give you at least 7 weeks on to make some gains. After your last shot of sust you will still have a large amount of test in your system for up to three weeks.
