Its enanthate. Shot it once! The ester wont let your blood levels move that much. Obviously shooting EOD or twice a week will keep them a little more constant, but its not anything that will be noticable.
Personally the way I would use 750 mg of the ICN's would be 1.5 ml's twice a week. Monday and Thursday. Thats how I have used those in the past and I have liked the results. Of course, as long as you stay within the drugs parameters, its more or less just personal preference with an ester like that.
Normal price internationally is about 7$ an amp. Domestically I have seen people pay gym prices of 15+ an amp. I think it is worth it at either price though. It is a superior product that is overfilled and underpriced.
