This is one of the longest ester used in any steroid. It has a very long half-life, over 2 weeks (around 15 days), which means the active life of the ester is almost a month. In simple terms, from the time you inject decanoate, it takes roughly 30 days to leave your system. Though, you can expect the peak of this ester to be around 11-12 days not 15.
Interestingly, the decanoate ester is the main reason sustanon is considered a "once a month" drug. Users tend to think you can inject one injection of sustanon per month based on this ester alone. This is true for testosterone replacement therapy (TRT), but it's a complete fallacy for bodybuilding. Think of it this way, by the time you get to day 11-15 (~2 weeks in), you peaked and you used up most of the steroid. Therefore, you need another injection to keep blood levels steady.buy Testosterone Decanoate powder
For the low testosterone patient, if you supplement with Testosterone Propionate you will suffer no more. This is the primary effect of Testosterone in this regard. Levels were low and now they're not. Then we have the performance enhancing athlete, and as a versatile anabolic steroid the effects of Testosterone Propionate will cover a wide breadth in this category.
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.
Then we have the cutting phase, and Testosterone Propionate can be invaluable here. In order to lose body fat we must burn more calories than we consume. You can follow the healthiest diet in the world and exercise yourself into the ground but if you are not in a caloric deficit you will not lose body fat. Unfortunately, this necessary caloric deficit puts our lean muscle tissue at risk, especially as we become leaner. The human body does not want to lose body fat due to its survival instinct. As energy demands increase during dieting the body will take what it needs from wherever it wants, and this is often from your muscle tissue. The key to successful dieting is not only losing fat but minimizing muscle tissue low. High testosterone levels will enable you to achieve this efficiently. Without an anabolic protectant like Testosterone Propionate, some lean muscle tissue loss will occur, this is a given. Due to the metabolic enhancement provided by high testosterone levels, the individual will also burn fat at a more efficient rate.
