MK-677 (Ibutamoren)
researchOral growth hormone secretagogue — no injections needed, taken as a daily capsule
Availability in Thailand
MK-677 is available from Thai peptide vendors as oral capsules or tablets. It is one of the few growth hormone-boosting compounds that does not require injections, making it the most convenient option in this category. Several Thai vendors stock it.
Prescription: Not required from vendors. Available as a research compound.
Legal status: Not a controlled substance in Thailand. Available as a research compound. Not approved for therapeutic use in any country.

Overview
MK-677 (ibutamoren) is a non-peptide ghrelin receptor agonist that stimulates growth hormone and IGF-1 release — taken orally as a daily capsule or tablet. It is technically not a peptide but is universally discussed alongside peptides because it targets the same GH pathways. Its key advantage is convenience: no injections, no reconstitution, no refrigeration. Just take a capsule once a day.
In Thailand, MK-677 is available from several peptide and research compound vendors. It is particularly popular among bodybuilders and fitness enthusiasts who want GH benefits without the complexity of injectable peptide protocols. A two-year human clinical trial demonstrated that daily MK-677 significantly increased GH and IGF-1 levels to those of younger adults and increased fat-free mass.
How It Works
Ghrelin receptor activation
MK-677 mimics the hunger hormone ghrelin by binding to the growth hormone secretagogue receptor (GHS-R1a) in the brain and pituitary. This stimulates pulsatile GH release, similar to how ipamorelin works but through oral administration rather than injection.
Sustained GH and IGF-1 elevation
A single daily dose elevates GH and IGF-1 levels for up to 24 hours. In a two-year trial with older adults, daily dosing raised GH and IGF-1 to levels typical of younger adults. Unlike injectable GH secretagogues that produce short pulses, MK-677 creates a more sustained elevation.
Does not suppress natural hormones
MK-677 does not suppress the body's natural production of testosterone, cortisol, or other hormones (unlike anabolic steroids). GH elevation is achieved through stimulation of the body's own pathways, not exogenous hormone introduction.
Protocol Quick Reference
Benefits & Uses
- No injections required: The only oral growth hormone secretagogue — taken as a simple daily capsule or tablet
- Increased muscle mass: A two-year human trial showed significant increase in fat-free mass compared to placebo in older adults
- Improved sleep: GH release during sleep is enhanced, and users consistently report deeper, more restorative sleep — often the first noticed benefit
- Convenient protocol: One capsule daily, no reconstitution, no refrigeration, no syringes — the simplest GH protocol available
- Anti-aging effects: Restores GH and IGF-1 to youthful levels, supporting skin quality, recovery, and cellular repair
- Appetite stimulation: Increases appetite through ghrelin receptor activation — beneficial for bulking, potentially unwanted for cutting
Side Effects
Common
- Increased appetite — significant in most users, especially in the first few weeks
- Water retention and bloating — typically temporary, resolves within 1-2 weeks
- Mild lethargy or drowsiness — especially if taken before bed
- Numbness or tingling in hands — related to GH elevation, usually mild and transient
Less Common
- Mild joint stiffness — from water retention
- Vivid dreams
- Mild headaches during initial use
Serious
- Elevated fasting blood sugar and reduced insulin sensitivity — MK-677 can raise blood glucose levels. Monitor if you have diabetes, pre-diabetes, or insulin resistance. This is the most clinically significant concern
- Elevated prolactin — some users report mild prolactin elevation, though this is not consistently observed
- Not recommended for individuals with active cancer — GH and IGF-1 elevation can promote tumour growth
- Not recommended for uncontrolled diabetes
- Banned by WADA — athletes subject to anti-doping testing must avoid

FAQ
Is MK-677 a peptide?▼
Technically no — it is a non-peptide compound (a peptidomimetic) that mimics ghrelin's action on the GH secretagogue receptor. However, it is universally discussed alongside peptides because it targets the same growth hormone pathways and is sold by peptide vendors. Its key advantage over actual peptides is oral bioavailability — no injections needed.
Does MK-677 require injections?▼
No — this is its biggest advantage. MK-677 is taken orally as a daily capsule or tablet. No reconstitution, no syringes, no refrigeration. It is the simplest growth hormone protocol available.
Will MK-677 make me hungry?▼
Very likely yes. Appetite stimulation is one of the most consistent effects, especially in the first few weeks. This is beneficial for bulking but undesirable during cutting. Taking it before bed can reduce the impact during waking hours.
Is MK-677 safe for long-term use?▼
A two-year human clinical trial showed it was generally well tolerated, with the main concern being elevated fasting blood sugar and reduced insulin sensitivity. Long-term use requires monitoring blood glucose levels. It is one of the few GH-related compounds with multi-year human trial data.
Is MK-677 available in Thailand?▼
Yes — available from Thai peptide and research compound vendors as oral capsules. No prescription needed. Check our vendor directory for current options.
