Hold on...not so fast! Test is not test.
Milligrams below are the estimated amount of active testosterone per 100mg.
Testosterone Base: 100mg/
0 ester
Testosterone Acetate: 83mg/
17mg ester
Testosterone Propionate : 80mg/
20mg ester
Testosterone Isocaproate: 72mg/
18mg ester
Testosterone Enanthate : 70mg/
30mg ester
Testosterone Cypionate : 69mg/
31mg ester
Testosterone Phenylpropionate: 66mg/
34mg ester
Testosterone Decanoate: 62mg/
38mg ester
Testosterone Undecanoate: 61mg/
39mg ester
Both enanthate and cypionate are long ester and there is a miniscule difference between testosterone E and C.
An example of data above in practical application:
500mg of test prop yields 400mg active testosterone
500mg of test enanthate yields 350mg active testosterone
500mg of test cypionate yields 345mg active testosterone
