TH1895B - Mammalian PGRF Preparation Process - Google Patents

Abstract

has shown the synthesis process of PGRF, which is a strong substance To stimulate human release of pituitary GH, the formula is as follows (chemical formula) This peptide or its parts containing Biological activity or its analogues known to Replaces and/or fills well and salts of the aforementioned substances. The above are non-toxic and may be administered to mammals, mammals as well as humans and may be used for the diagnosis of peptides. These are useful in stimulating GH release and stimulating animal growth. warm-blooded non-human including also using To improve aquaculture
