fluctuating as all esters are for stable hormone levels go by the half-life of the hormone your injecting ,Half-life of cyp is about 12 days, So considering the half-life For more stable blood levels and to keep blood levels high inject at or around half of the half-life of the hormone. With cyp about every 4-5 days, Injecting right at the half-life would let blood levels drop to low. Like everyone stated 2 injects every week will work with cypioante for most and BB purposes.
I'll agree on that, if your using 1000mg or more of test EW smaller injects Eod or ED will be alot easier on inject sights than taking that much in two shots, especialy with some of the high mg mixes. I've done that and it keeps inject sights from getting eartated and keeps scartissue down imo.
