MK 677 (Ibutamoren) - Dragon Pharma

Buy MK 677 25 mg tablets by Dragon Pharma at XSteroids. MK 677 is ibutamoren, an oral ghrelin receptor agonist that raises growth hormone and IGF-1 - and despite being sold next to the SARMs, it is not one. Dragon Pharma supplies it as 25 mg tablets, 100 per pack. This guide covers what it actually does, mk 677 dosage practice and what the research does and does not show.

Ibutamoren is an Investigational New Drug and is not approved for human consumption, so the information below is educational only.

About MK 677 (Ibutamoren) by Dragon Pharma

Ibutamoren, also coded MK-0677 and LUM-201, is a potent, long-acting, orally active and selective non-peptide agonist of the ghrelin receptor. It is a growth hormone secretagogue: it mimics the GH-stimulating action of ghrelin, the hormone the stomach releases before meals.

That mechanism is why it is grouped with peptides rather than with SARMs. A SARM acts on the androgen receptor; ibutamoren acts on the ghrelin receptor. Calling it a SARM is a marketing convenience, not pharmacology.

How MK 677 Works

Raising GH and IGF-1

Ibutamoren sustains activation of the GH-IGF-1 axis, and research describes increases in growth hormone secretion of up to 97%. In humans, IGF-1 levels stay elevated for up to 24 hours after a single oral dose, even though the drug's own half-life is only four to six hours - the hormonal effect outlasts the compound itself. It also raises cortisol levels, which is part of its endocrine signature.

What It Does to Body Composition

Its effect on lean mass is the headline finding: increases in lean body mass with no change in total fat mass or visceral fat. That is a meaningful distinction from most physique compounds, and it also explains why the research focuses on people with low GH levels.

MK 677 Dosage and Cycle Practice

Dosing

The 25 mg tablet matches the dose used in the small sleep study, where participants took it at bedtime. Because GH is released mainly during sleep, evening dosing is the convention. As with any secretagogue, the response is dose-dependent and blood work - IGF-1 and glucose in particular - is how you see whether it is working.

What Users Report

The subjective effects people mention most often - increased appetite, water retention and a heavier, rounder look in the first weeks - are user reports rather than findings from controlled trials. None of that appears in the clinical literature as an established effect, and readers should treat it accordingly rather than as documented pharmacology.

MK 677 Side Effects and Research Status

What the literature does document is a rise in cortisol alongside the GH and IGF-1 increase, and the fact that the compound remains an Investigational New Drug - never approved for human use. Development continues for growth hormone deficiency, where phase 2 work (OraGrowtH210 and 212) reported that primary and secondary endpoints were met in paediatric GHD, but that is development, not approval. Anyone considering it should know that it is not a SARM, so SARM-specific expectations and warnings do not transfer directly.

MK 677 vs SARMs and Peptides

Because it is sold alongside Ostarine and LGD 4033, people often assume it belongs to the same family - it does not. Those compounds act on the androgen receptor, while MK 677 works through the ghrelin receptor and the GH-IGF-1 axis, closer in spirit to the injectable secretagogues and repair peptides such as BPC 157 and TB 500. It is frequently stacked with GW 501516 or S 23 in research logs, but the mechanism remains separate.

Storage Instructions
