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.
It's not difficult, hard, or complicated...it's actually really, really easy to do!
But strangely enough, some guys just don't get it.
Which brings me directly to disclaimer number 2 (sorry folks, but this has to be done).
If for some reason you do not understand the concept above, or are not willing to do it, please leave this page now.
The LAST thing I want is for you to order one supplement, take it 36 days in a row, then email me, complaining that it doesn't work.
I'm tired of getting emails like this!
If you can't or will not cycle, move on please, there's nothing to see here.
One of the most common questions asked about HGH is whether it can make users grow taller. Between the ages of about 12 and 18, your body is still growing. During this time, the administration of HGH can help you add inches to your height. As such, HGH is an essential part of therapy for children who have growth disorders such as dwarfism. However, between 18 and 21 years old, growth plates on your bones fuse together and essentially “lock” your height. Administering HGH may cause individual bones in your body to thicken, but it will not lengthen them.
