Real Sermorelin, originally called Geref, encourages an increase in natural HGH production.
It is an advantageous method of boosting Human Growth Hormone levels without having to inject HGH subcutaneously.
The Sermorelin molecule is a pituitary gland secretagogue for Growth Hormone (GH) of the GH releasing hormone class of molecules (GHRH).
A secretagogue is a molecule messenger that acts like a stimulant telling another organ to make more of something. It's a kind of request signal that says, "Hey, I need more of something specific!" and "I need this amount of specific."
The amount of what it requests is dependent upon how much of the molecule messenger is released, and it gets more complicated because somatostatins can also tell the pituitary gland to stop production of GH. So there are on and off switches in the body that are made up of molecules.
The problem with HGH is that if you inject it in doses higher than low optimal amounts, somatostatins can't have an effect on bringing the HGH levels down and some people have an immune reaction, getting flu-like symptoms.
Hypothalamus and GHRH versus man-made Geref (Sermorelin).
Growth hormone-releasing hormone is released by the arcuate nucleus (or infundibular nucleus) which is an aggregation of neurons in the mediobasal part of the hypothalamus, in its endogenous forms and as somatorelin in its pharmaceutical form.
It is the specific secretagogue message guy that informs the pituitary gland that it needs to start putting together more HGH molecules and releasing them into the body.
Sermorelin is essentially the same thing as growth hormone releasing hormone (but molecularly shorter 44 polypeptides versus 29) because it has the same job, it tells the anterior lateral wings of the pituitary gland that it needs to make HGH (as already stated) and then pump that HGH into the bloodstream.
So basically you have two choices to increase your HGH levels, you can either inject HGH or inject the hormone that tells your body to make more HGH.
