New GH?

[weakestlink]

The following is an description that I saw on a chem site. Is this the real thing for anybody who has tried it or knows about it.


NEW! Growth Hormone (1-43) for research 1mg $290.00

Growth Hormone (1-43) is a pure growth hormone with a very unique amino acid chain. The product also is showing great promise to be an alternative for GH therapy in the future. This form is for lab / animal/ andin vitro research only. Not for human use. This is a synthetic form of growth hormone.

This one as well

NEW GROWTH HORMONE (6-13) 1mg FOR RESEARCH $85.00

Growth Hormone for research use only. This is real growth hormone for research and laboratory use only. This product must be shipped in a temperature controlled enivironment and be refrigerated for stability. The amino acid chain is six thru thirteen. This product has shown to be very effective in raising Gh plasma levels. It is now available. This product is for in vitro studies. This is a synthetic form of growth hormone.

These are GF fragments as indicated by () which depicts the amino sequence with respect to the whole GH chain (1-191).

These frags have some research and studies behind them if you search pubmend. They do not produce all the effects of the GH sequence but instead exhibit few charateristics. Both are mainly studied for their hypoglycemic effects.
6-13 mainly exhibits some insulin potentiating effects and increased glycogen sysnthesis.

Here is a reply I made on a 6-13 study in another thread which has some info as well as the study link:

I have not seen any evidence of these frags actually increasing actual GH levels, as they are a GH frag, and not a secretagogue/GHRH analog. With what I have seen I do not believe these frags can compete with the full actions of the complete GH peptide.

Basically Bob said it all.

You might find this little snippet from the intro of the study ""Effects of oral administration of a synthetic fragment of human growth hormone on lipid metabolism", M. A. Heffernan, Am J Physiol Endocrinol Metab 279: E501-E507, 2000 to be a handy summary:

...
Advances in peptide synthesis technology have made it possible to produce specific and discrete functional domains of hGH (9), and there is now considerable evidence supporting the concept of discrete structural domains within hGH responsible for the different metabolic functions of the intact hGH (4). For example, Ng et al. (13) have reported that the insulin-like actions of hGH may reside in the amino-terminal region of the molecule [hGH-(6---13)]. This was later confirmed to be within hGH-(1---43), another well-known hypoglycemic fragment that exists in the circulation of humans and results from posttranslational cleavage in vivo (20, 29). On the other hand, the carboxy terminus of the hGH molecule [hGH-(177---191), or AOD-9401] has been identified as the lipid mobilizing domain of the intact hormone. This fragment inhibits the activity of acetyl-CoA carboxylase in adipocytes and hepatocytes, and it acts to reduce glucose incorporation into lipid in both isolated cells and tissues (30). It has been suggested to be the lipolytic domain of the hGH molecule. Previous studies in our laboratory have shown that weight loss can be induced by chronic intraperitoneal treatment of AOD-9401 (12).
