As a result of having an ester attached to the hormone used, mg value of the Active hormone is less than the dose by the weight of the esters attached.
Although the table below shows the relative content for testosterone, it is in fact the same with any hormone. This multiplying the value in the table with the dose administered gives you the exact active hormone without ester administered.
example:
Administered; 1mL of 250mg/mL Testosterone Enanthate
Actual Hormone administered; 0.72 x 250 mg =180 mg 180 mg of Testosterone once the ester is cleaved off in the body.
| Testosterone Ester | Relative Testosterone content |
| Testosterone | 1.00 |
| Testosterone propionate | 0.84 |
| Testosterone isobutyrate | 0.80 |
| Testosterone isocaproate | 0.75 |
| Testosterone caproate | 0.75 |
| Testosterone phenylpropionate | 0.69 |
| Testosterone cypionate | 0.70 |
| Testosterone enanthate | 0.72 |
| Testosterone decanoate | 0.65 |
| Testosterone undecanoate | 0.63 |
| Testosterone buciclated | 0.63 |
