I would like to see your research. Cypionate and enanthate are almost identical esters. Acually test E and cyp BOTH have a MW of 412.6112. Test E has an ester of only 7 instead of 8 carbons in length as Cyp does. So, when taking an amount of an esterified steroid, that amount in terms of weight is a combination of both the ester and the steroid. So, the longer the ester is, the more of the weight it takes up. This in fact would make Test E a slight bit more test for the money. In the end, if doing weekly or bi weekly injections, you will notice very little difference.
