While the human body manufactures an endogenous Testosterone level in the range of 70mg/week, the Testosterone dosage required for physique and performance enhancement must sit well above that, with a minimum being in the range of 300 – 500mg per week for beginners, for example. Intermediate and/or experienced anabolic steroid users can venture even higher than that. In addition to the higher bodybuilding dosage, the injections must be administered much more frequently. While TRT patients can ‘get by’ with a single 250mg injection of Testosterone Enanthate once per week (or even once every two weeks as is commonly applied clinically), an athlete or bodybuilder would have to administer 250mg of Testosterone Enanthate twice per week (for a total of 500mg) in order to experience a steady onset of performance and physique enhancing benefits. This is very necessary due to a constant steady peak blood plasma level of the anabolic steroid that is necessary for constant biological action within muscle tissue in the body. Testosterone Enanthate, as mentioned earlier in this article, exhibits a half-life of 7 – 10 days, but although its half-life is 7 – 10 days, sharp declines in blood plasma levels begin to occur several days before the end of the half-life period. When performance and physique enhancement is desired, the administration of doses must occur more frequently in order to keep blood plasma levels elevated as best as possible. For medical purposes such as TRT, sharp spikes and peaks and valleys in blood plasma levels can be afforded (although it is still not optimal), as the patient is simply utilizing Testosterone to obtain normal physiological levels, and is therefore not particularly concerned with dramatic performance or physique changes on a weekly basis.
Testosterone can be administered parenterally , but it has more irregular prolonged absorption time and greater activity in muscle in enanthate , undecanoate , or cypionate ester form. These derivatives are hydrolyzed to release free testosterone at the site of injection; absorption rate (and thus injection schedule) varies among different esters, but medical injections are normally done anywhere between semi-weekly to once every 12 weeks. A more frequent schedule may be desirable in order to maintain a more constant level of hormone in the system.  Injectable steroids are typically administered into the muscle, not into the vein, to avoid sudden changes in the amount of the drug in the bloodstream. In addition, because estered testosterone is dissolved in oil, intravenous injection has the potential to cause a dangerous embolism (clot) in the bloodstream.
Sometimes you’re a moron. First, how do you know that his routine is Youtube is the real, year long routine, second machines with a lot of load may create the tension for muscle growth, of course for natty guys machines are not very effective, for the chemical guys who are much more stronger it can actually work. How do you know he is a synthol user? his muscle are pretty in shape, synthol always look weird, you’re making up stuff, he truly look like a guy with real dense muscle. I believe his muscle development is because of 2 genetics factors, bone structure and a highly efective response to the abuse of steroids, HGH and insulin, because not everybody respond the same to steroid abuse. How do you know he can track his training, this dude dedicate his entire life to this, he doesn’t go out of oxygen gym and have people to track his training, in addition there are rumors that his sponsor have access to very high quality chemicals.
