High-Quality Liquid MK-677 for Sale

MK-677 (Ibutamoren) is an investigational compound that acts as a ghrelin receptor (GHSR-1a) agonist and growth hormone secretagogue in research settings. It has been studied for its potential to stimulate the growth hormone/IGF-1 axis. MK-677 is not approved for medical or consumer use.

Unlike ghrelin, MK-677 is not a peptide, which allows it to be orally active and capable of crossing the blood–brain barrier. It acts on ghrelin receptors in the hypothalamus and pituitary gland to stimulate the growth hormone–IGF-1 axis, increasing circulating levels of both hormones.

Although MK-677 is sometimes grouped with selective androgen receptor modulators (SARMs) in non-scientific contexts, this classification is inaccurate, as it does not interact with the androgen receptor. Instead, MK-677 enhances endogenous hormonal secretion through neuroendocrine pathways without the direct suppressive effects typically associated with exogenous GH administration.

MK-677 vs. Other Growth Hormone Secretagogues

MK-677 is a potent ghrelin receptor agonist, not a hormone, that stimulates the body’s natural release of growth hormone (GH) and insulin-like growth factor 1 (IGF-1). While it is often listed alongside selective androgen receptor modulators (SARMs) in research chemical catalogs, this is a marketing grouping rather than a pharmacological classification, as MK-677 does not act on androgen receptors (Source).

Research shows that MK-677 has advantages over injectable growth hormone–releasing peptides (such as GHRP-6 and GHRP-2). A single oral dose of MK-677 produces a sustained elevation of IGF-1 for approximately 24 hours without disrupting the body’s natural pulsatile GH secretion. Its oral bioavailability makes it more convenient to administer in research compared to injectable peptides (Source).

Proper dosing is critical in research settings to maintain consistent hormonal elevations and reduce the risk of side effects. Clinical studies have demonstrated dose-dependent effects on GH and IGF-1, with excessive dosing potentially increasing the incidence of fluid retention, joint discomfort, and insulin resistance (Source).

In limited clinical studies, MK-677 increased GH and IGF-1 levels, which may influence body composition parameters under controlled research conditions. Data are insufficient to determine effects on endogenous androgen or testosterone regulation in humans. Some experimental data suggest potential additive effects when MK-677 is co-investigated with other growth hormone-releasing peptides like, Tesamorelin or Ipamorelin, in controlled research settings. These findings remain preliminary and unverified in large-scale clinical trials.

MK-677 FAQs

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

Research in older adults and specific patient populations shows that MK-677 can elevate endogenous GH and IGF-1 levels from baseline. However, the magnitude and clinical significance of these increases differ from exogenous growth hormone therapy, and MK-677 is not approved or validated as a substitute for HGH treatment.

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

Available studies up to two years indicate that MK-677 did not fully suppress endogenous GH pulsatility, but long-term effects on natural GH regulation beyond that period remain unknown and require further investigation.

Can MK-677 trigger gynecomastia?

A two-year human study on MK-677 found that subjects experienced a significant decrease in the risk of developing gynecomastia compared to injectable growth hormone. In this study, the incidence of gynecomastia in the MK-677 group was also compared to a placebo group to assess the safety profile of the compound.Data on MK-677 and gynecomastia risk are limited. Some clinical trials have not reported increased incidence compared to placebo, but these studies were short-term and conducted under medical supervision. Further research is needed to confirm long-term endocrine safety.

Does MK-677 suppress testosterone?

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

Can MK-677 raise blood sugar?

Data suggests that growth hormone secretagogues, like MK-677, may harm glucose tolerance and increase blood sugar levels with continuous testing.

Is MK-677 Safe to Use?

MK-677 (Ibutamoren) is an investigational compound that has not been approved by the FDA or any other regulatory agency for human consumption. While early research explores potential effects on GH and IGF-1 levels, long-term safety data in healthy populations are lacking. Reported side effects in clinical contexts include fatigue, water retention, and changes in glucose tolerance.Despite decades of research into its effects on growth hormone (GH), IGF‑1, body composition, and bone health, there is insufficient data on its long-term safety in healthy individuals. Long-term use of MK-677 is still being evaluated in clinical trial settings. Some side effects, such as fatigue, have been reported during prolonged oral treatment with MK-677 (Source).

Why choose Sports Technology Labs as the best place to buy MK-677?

The main reasons customers choose Sports Technology Labs for MK-677 include our commitment to product quality, safety, and reliable service. Independent research has shown that quality control in the broader SARM and research compound industry is highly inconsistent.

In a 2017 JAMA study analyzing 44 products sold online as SARMs, only 52% contained the advertised compound, 59% differed in quantity from what was on the label, 39% contained unapproved drugs, 25% included unlabeled substances, and 9% contained no active ingredient at all.

These findings underscore the critical importance of sourcing research compounds from reputable companies that provide third-party analytical testing to verify purity and identity.
