MK-677 (Ibutamoren)- Summary
- Pancragen is a tripeptide bioregulator (Lys-Glu-Asp) developed by Professor Vladimir Khavinson, tissue-specific for the pancreas. It supports the function of both exocrine and endocrine pancreatic cells, promotes normalization of insulin secretion from beta cells, and may offer protective effects against pancreatic aging and diabetic progression.
- MK-677 (Ibutamoren) is an orally active, non-peptide ghrelin receptor agonist that increases growth hormone and IGF-1 levels. Unlike injectable GHRPs, it can be taken orally and has a 24-hour half-life, making it convenient for sustained GH optimization.
