HGH Human Growth Hormone is coming out with a new version of the product. You will only have to take the HGH product once a week or longer opposed to once a day. There are a lot of generic HGH products out there and so Merck-Serono is afraid this will effect there sales. HGH is hoping to get this out before the generic drug comes out with this product as well. Merck-Serono will be working with Ambrx to get this in action and to make this HGH product last longer in your system. Right now it is in the clinical stages and hope it will be out soon.
