Local (regional) lipolysis (in other words, localized site shredding) with GH sq is proven. [Am J Physiol Endocrinol Metab. 2004 Mar;286(3):E488-94. Epub 2003 Nov 04. Additive effects of cortisol and growth hormone on regional and systemic lipolysis in humans.]
Therefore, many people administer GH in the abs or butt for localized fat burning. Scientifically, there is significant fat burning with GH locally. And, anecdotally, bodybuilders report visually significant local fat loss to correspond to the laboratory data on the same subject. I personally, however, have not done this with GH, so I cannot say. I plan to try this in the next 8 weeks on my abs though. So I will let you know.
