The difference between testosterone products

The difference between testosterone products

Some friends often ask what is the difference between three different forms of testosterone, and how should we choose?

Arvin explains the differences between the three types of testosterone

1. Test-C (testosterone cyclopropionate) half-life is 12 days

2. The half-life of TEST-E is 10.5 days

 3.SUST (mixed testosterone) has a half-life of 15-18 days

What is the half-life of a drug?

The half-life of a drug is the time it takes to reduce the maximum plasma concentration of the drug by half. For example, testosterone cyclopropionate has a half-life of 12 days, after which its blood concentration is half of its maximum; Another 12 days and another half; Another 12 days and another half, the blood concentration is only a quarter of the peak. The half-life of a drug reflects how quickly it reaches its peak after being injected into the body. If the interval between medications is too long, blood levels can drop and endocrine disorders can occur. If the drug is administered too frequently, it can put stress on the liver, which metabolizes both the injection and the oral dose.

For example, today I got a 100 mg injection of testosterone propionate, in 12 days I will get 50 mg testosterone, another 12 days half-life is divided by two equals 25 milligrams of testosterone, usually in order to make the blood drug concentration rising steadily so will choose a half-life divided by two time is injected at the time, of course this is not the use of the absolute. A lot of people make CYCLE with two or four injections at the same time . if you give a large dose in a single injection it can cause local swelling, so it’s better to give it twice a week.

Finally, mixed testosterone, which many people don’t use well, is made up of a mixture of four or five different lipids with different half-lives. The most important thing to know about testosterone propionate is because testosterone propionate is the shortest acting testosterone in the mix, and if you don’t have the right time to release testosterone you can easily have low levels of testosterone in your blood. Testosterone propionate is different from testosterone in other lipid chains and has a half-life of three days. You can’t use mixed testosterone if you inject it half the time of the half-life. The timing of the injection needs to be combined with the half-life of each testosterone to achieve the desired effect.
