Testosterone Propionate is an oil-based injectable Testosterone compound. The added Propionate ester slows the rate in which the steroid is released from the injection site and it is comparatively much faster acting than other testosterone esters. Testosterone Propionate was the first androgenic steroid to be synthesized and it should be injected more frequently than Cypionate and Enanthate compounds. But the effects are generally the same in all of these forms of Testosterone. However athletes prefer small doses of Testosterone Propionate over large doses because they find it easier to control a series of negative side effects. Many consider Test Propionate to be the mildest Testosterone ester, and the preferred form for the dieting/cutting phases of training.
Bodybuilders and athletes find it to be effective in gaining body mass and maintaining the body muscles during the cutting period. In essence Testosterone expands the nitrogen retentive properties of body tissues and assists to protein synthesis in the body tissues. Testosterone Propionate also increases the effect of IGF 1 on the muscle tissues that results in the creation of new muscle fibbers growth or existent muscle fibbers strengthening. Testosterone Propionate also has the capacity to increase the activity of satellite cells.
The Testosterone Propionate cycles in the body should be carefully planned to avoid the fluctuation of blood pressure. The most common combinations in using Testosterone Propionate are with anti-estrogens Tamoxifen and Proviron, and products like with Methandrostenolone and Nandrolone for achievement of bulking effect. A combination with Halotestin should have more extreme effect on subcutaneous body fat and muscle hardness.
