MK677 also known as Ibutamoren or Nutrabol is a very unique growth hormone secretagogue. MK677 (Ibutamoren/Nutrabol) is not a peptide, is orally active, and has a long half-life (unlike most growth hormone secretagogues.  MK677 (Ibutamoren/Nutrabol) studies have shown it to be very effective in elevating growth hormone and IGF – 1 level for up to 24 hours after administration, and it requires no injection. This investigational compound first entered into development more than 15 years ago in an effort to find an orally administered alternative for growth hormone replacement in adults and children with deficiencies. MK677 (Ibutamoren/Nutrabol) does not elevate cortisol levels, which most currently available growth hormone secretagogues do.

MK677 (Ibutamoren/Nutrabol) is a selective agonist of the ghrelin receptor (GHSR) and mimics the growth hormone stimulating the action of Ghrelin. MK677 (Ibutamoren/Nutrabol) clinical studies have shown the compound to be effective in increasing lean body mass and bone mineral density.

People frequently mistake MK-677 (Ibutamoren/Nutrobal) for a steroid or SARM (selective androgen receptor modulator, which it is not. MK677 (Ibutamoren/Nutrobal) is available from ELV Bioscience for research or laboratory use.
