The short answer
The difference between testosterone enanthate and testosterone cypionate is roughly half a day of half-life and about one percentage point of testosterone by weight. Both are long esters supplied in oil at similar concentrations. Neither difference is large enough to be the deciding factor between two products; concentration, price, stock and batch verification all vary more.
