GTIN: 90190876298765 SKU: 5-1 Categories: ,


MK-677, also known as Ibutamoren, is a growth hormone secretagogue that is sometimes incorrectly classified as a selective androgen receptor modulator (SARM). When administered orally, MK-677 mimics the action of the hunger hormone ghrelin and, by doing so, increases growth hormones (GHs) in the body. It is powerfully effective in boosting levels of insulin-like growth factor 1 (IGF-1). Unlike growth hormone and most growth hormone secretagogues, MK677 is orally bioavailable so it does not require injection for proper absorption. Sports Technology Labs is the best place to buy MK-677 for sale on the internet.

MK-677 has displayed multiple effects in vitro, including:

  • Increased GH levels
  • Increased muscle mass
  • Increased bone density
  • Faster muscle growth
  • Improved immune function
  • Better sleep
  • Increased appetite
  • Reversal of growth hormone deficiency


However, it must be emphasized that MK-677 has not been approved by the Food and Drug Administration (FDA) for human consumption. It should be used for research purposes only.

Nonetheless, several studies have been conducted that suggest MK-677 holds enormous promise as a drug that could enhance human health:

  • One study found that MK-677 increased insulin-like growth factor I (IGF-I) and IGF-binding protein-3 (IGFBP-3) levels, and potentially could be used to counter somatotropic deficiency [1]
  • Another study found that MK-677 increases bone turnover and osteoblast activity in older adults [2]


Further important research into MK-677 will be performed in the years to come.

MK-677 FAQs

Can MK-677 raise growth hormone and IGF-1 to the same extent as therapeutic treatment with HGH?

Studies have demonstrated the ability of MK677 to raise endogenous levels of HGH and IGF-1 [3].

Can MK-677 suppress your body’s natural GH production?

There is presently no evidence that MK677 compromises the body’s natural production of GH long term. More information may be available in the future

Does MK-677 suppress testosterone?

MK-677 does not act on the feedback loop for testosterone in the human body and is not expected to suppress natural testosterone levels.
