The esters in the 3 steroids are all very fast to release. At the least, you want to inject them EOD. I prefer to use the ED, but either will work. Dose will depend on experience. If you are newer to gear, having only used for a couple yrs or less, I'm sure you'll do fine on 2CC EOD or 1CC ED. This combo is the holy grail of contest prep. They work great together to get you looking very hard and dry. Even though this cycle will have a lower converstion to estrogen, I would still use an AI to stay as dry as possible, especially if you are doing a contest. .5mg EOD is what I would start with and if you are cutting for a show, I would probably get a little more aggressive in the last 2 wks, IF needed.
I would keep the length at about 8 wks.
