I took a frequently prescribed amount of HGH for anti aging (1.5 ius daily) along with testosterone gel for 1 year. My labido was better (quality rather than quantity), my sense of well being improved and my skin seemed softer and tighter. I also made some minor gains in strength and muscle mass which I have held onto. Its quite possible these things may have been the result of a placebo/wishful thinking effect - I did pay better attention to my diet, training and recovery after I started using it.
One thing that was definitely for real was the loss of stored bodyfat.
The combined cost of the doctor, blood work, the HGH itself and other tests made it VERY expensive and the benefit did not justify the cost... IMO.
