Is your body unable to produce its own HGH?

If you consume exogenous HGH, it may signal to your body that it is producing too much HGH, and once you stop consuming exogenous HGH, you might see some adverse effect.

You can stimulate HGH through HIIT, resistance training, fasting, reducing stress or getting sufficient sleep. Eat lots of animal products that has good amount of fat, because you need fat in order to make hormones. These are methods you can try out before choosing to go with external interventions.
