100 mcg is the saturation dose for ghrp-6. If you need help with how to mix it to get a certain concentration when your ghrp arrives let us know.
Also, there's decreasing returns in growth hormone release when dosing over 100 mcg. You're better off doing two 100 mcg shots separated by 3 hours or so rather than 200 mcg all at once for greater growth hormone total release. Plus this helps to mimic the way GH pulses naturally.
