Test Prop 100mg Excel Pharma is the oil-based injectable testosterone steroid. There is less ester per vial, thus there is more actual testosterone per injection which produces better results.

The added propionate ester will slow the rate in which the steroid is released from the injection site, but only for a few days. Therefore comparatively, Testosterone propionate is much faster acting than other testosterone esters such as cypionate or enanthate, and requires a much more frequent dosing schedule. Testosterone propionate is generally administered (at least) every third day, while cypionate and enanthate are injected on a weekly basis.

Those who are not bothered by frequent injections will find that propionate is quite an effective steroid. It is of course a powerful mass drug, capable of producing rapid gains in size and strength.

Testosterone Propionate is the shortest-estered testosterone compound with a slower rate of release than un-esterified Testosterone, but a faster rate of release than all the rest of esterified testosterones.

The Propionate ester expands Testosterone's half-life to about 4 and a half days.
