When an ester is attached to a compound the ester makes up a percentage of the total weight of the compound - for example, testosterone cypionate contains 69.9% testosterone per mg, whereas the cypionate ester makes up 30.1% of the total weight. However, testosterone propionate contains 83.7 mg of testosterone, per mg and its ester weight is 16.3% of the compound. Additionally, since shorter esters release the parent compound into the human bloodstream at a faster rate, gains are recognised at an increased speed.

Below is a list of the more commonly used esters, which have been grouped together according to the percentage of testosterone they contain per mg - additionally, i have added breakdown of how much money is spent on the product and how much is spent on the ester (based up on RRP in USD ($) of a 10ml vial using common dosages - Rested Retail Price (term used loosely LMAO).

Percentage of Testosterone per mg - RRP ($) - Value of test - Value of ester

No Ester: 100mg---------------------$45--------$45-------------$0
Propionate: 83.72mg-----------------$35--------$29.3-----------$5.7
Enanthate: 71.99mg------------------$45--------$25.2-----------$19.8
Cypionate: 69.90mg------------------$45--------$24.47----------$20.53
