Testosterone
"I have used the 1-ml once a month for several years and if I don't get it on time I start to feel tired and my anxiety increases.  Usually after the dose I start to feel better in a couple days.  After about 2-3 weeks I start to feel tired again.  The doctor won't increase the dosage though and I don't understand why.  Also, PLEASE don't inject in your arm!  There are several very good u-tube videos out there on how to inject in the leg.  Take your time it is very thick and oily, don't rush it.  Make sure it makes it into the leg muscle not just the skin."
