The short answer
Propionate and enanthate sit at opposite ends of the common ester range. Propionate clears in under a day and carries the most testosterone per milligram of any common ester. Enanthate runs for around four and a half days and carries less. This is the comparison where the choice of ester genuinely changes the shape of the result rather than trimming it at the margin.
