Test prop works by making the muscles hold onto nitrogen, which means the muscles hold onto more protein. Holding onto proteins means better usage of energy, which subsequently means increase in muscle size and strength. Test prop has the ability to stop muscle wasting so you keep all of the muscle mass you worked hard at getting. There is no muscle wasting from the glucocorticoid hormones and red blood cell production is increased, which subsequently allows more oxygen to come in the body. Higher oxygen level in blood cells mean that you will not tire as fast and as much, what will than aid in recovery times as well.
For the off-season athlete there is no anabolic steroid more important or beneficial than testosterone. High levels of testosterone will promote significant increases in lean muscle mass and strength. This is assuming that the individual is consuming adequate calories. Compounds like Testosterone Propionate are not magical, you will still need to feed your body enough calories. During an off-season period of growth, this means total caloric intake will need to be slightly above maintenance. This will, unfortunately, promote body fat gain. However, the key to a successful off-season is gaining lean tissue while minimizing body fat gain to the fullest extent possible. By supplementing with Testosterone Propionate you will be able to achieve this more efficiently. High testosterone levels will promote a stronger metabolic rate. This is not a license to eat like there’s no end in sight, but you should be able to make better use of your calories.
Males with Delayed Puberty: Various dosage regimens have been used; some call for lower dosages initially with gradual increases as puberty progresses, with or without a change in maintenance levels. Other regimens call for higher dosages to induce pubertal changes and lower dosages for maintenance after puberty. The chronological and skeletal ages must be taken into consideration, both in determining the initial dose and in adjusting the dose. Dosage is generally within the lower ranges and only for a limited duration, for example, 4 to 6 months. X-rays should be taken at appropriate intervals to determine the amount of bone maturation and skeletal development (see INDICATIONS and WARNINGS).
