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.
40mg’s of pycnogenol was used alongside with 1700mg’s of arginine and aspartic acid in a Bulgarian trial. The study had 40 subjects suffering from clinically evaluated erectile dysfunction, and they took the combination of these supplements for erectile dysfunction, 3 times per day (so 120mg’s of pycnogenol). Three months into the study, 92,5% of the test subjects reported that their ability to regain erections had returned 5 . In 2003, another group of researchers replicated the study with similar results using 120mg’s pycnogenol with 21 subjects 6 .
