Usage:

Testosterone propionate is therefore much faster acting than other testosterone esters such as cypionate or enanthate, and requires a much more frequent dosing schedule, in order to maintain stable blood levels. Can be used as pharmaceutical material. Its main function is to Promote metabolism. Anabolic effects include growth of muscle mass and strength, increased bone density and strength, and stimulation of linear growth and bone maturation.

The Propionate ester is much faster acting (2-3 days) than Enathate or Cypionate, and thus requires a more frequent injection schedule such as every day or every other day in order to keep blood levels as stable as possible. The benefit to this however, is that the steroid can be cleared from the body much more quickly after use is discontinued, thus making it a more preferable choice for tested athletes. Some bodybuilders also claim that Propionate tends to induce far fewer estrogen related side effects such as bloat than do the other esters of this powerful steroid.

Testosterone aromatizes very easily and therefore estrogen buildup and side effects can become an issue for users sensitive to these problems or those choosing to use a high dose of this compound. Therefore, bodybuilders often choose in incorporate an anti-estrogen such as Proviron, to help keep estrogen related side effects to a minimum. Extremely sensitive users, or users using very high doses (800-1200mgs) might find that stronger anti-estrogens. Androgenic side effects such as oily skin are also possible.

Details
 
Nandrolone undecylate is an effective compound that produces quality, long-lasting muscle gains. This is because of the relatively long half-life of the drug (around 8 days). Users  report mild side effects, with the biggest side effect being water retention.
 
 
Nandrolone is most commonly found with a cypionate, laurate, decanoate or plenylpropionate ester. Briefly explained, the ester determines how much of the given hormone is released over a period of time. Longer esters such as decanoate peak slowly and can keep stable blood plasma levels up to ten days, shorter esters such as the phenylpropionate peak more rapidly but the half-live is shorter.  Shorter esters usually release much more active hormone per mg than longer esters, and of course, allow thedrugs effects to leave your system more quickly.
