I am on my 4th day using the HGH patch. I wanted to share my initial thoughts on the product. The first thing I noticed was the ease of use. I simply cleaned an area to the right under my navel. The patch went on easy and I wore it overnight for about 8 hours. I took it off in the morning and will use a new patch tomorrow (one patch every 4 days). The first night I did not notice anything but the second night my sleep was better than usual and last night it was even better than the night before. That is the main effect I have noticed thus far but I am pleased for only being a few days in! I will keep everyone posted as I go.
