“Now everyone is starting off at a different level so depending on your last cycle adjustments can be made to fit each individual,” according to Piana. “It can be scaled down or up hopefully people can handle this part on their own. For the more advanced that are doing much higher doses of GH my reasoning is anything higher than iu a day will cause the intestines to grow and eventually you will have a growth gut also same goes for using insulin but everyone is free to add on whatever they choose. GH and insulin will put on more size than anything but in my opinion it will ruin the physique!”
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.
