It depends on how long you plan to run your fina. Assuming you are doing an 8 weeker and your already in the middle of week four, I would run what would amount to 330mg/ starting week 5. this would mean you would inject on weeks 5 6 7 and because of the time the cyp w/ stays in your system(approx 12 days) it should carry you through and taper off right at the end of week 8, so you can start your post cycle thearpy and have everything out of your system.That's how I would do it
