MK 677 (Ibutamoren) by Dragon Pharma
What Is MK 677 (Ibutamoren)?
MK 677, or Ibutamoren, is an orally active growth hormone secretagogue that mimics the action of ghrelin. By stimulating the ghrelin receptor it raises the amplitude of natural growth hormone pulses, which in turn supports higher IGF-1 output. Dragon Pharma supplies it as a convenient 25 mg tablet.
In bodybuilding and longevity research MK 677 is referenced less as a fast anabolic and more as a long-term recovery and recomp tool. Research logs commonly describe deeper sleep, better recovery between sessions, a fuller look to trained muscle and a steadier appetite, which makes it useful in high-volume training blocks and even off-cycle periods.
Each pack contains 100 tablets of MK 677 (Ibutamoren) by Dragon Pharma. It is a research compound, not an approved medicine, and is intended for laboratory research only.
MK 677 Research Use
MK 677 is taken orally, usually once per day, and research references most often describe amounts in the 10-25 mg range. Because of its effect on sleep, many protocols place the dose in the evening, and windows of 8-12 weeks are typical for recomp-focused work.
| Protocol reference | Amount | Note |
|---|---|---|
| Starting reference | 10 mg once daily | Evening dose, useful for appetite and sleep assessment |
| Common reference | 25 mg once daily | The most frequently cited full protocol dose |
| Duration reference | 8-12 weeks | Longer blocks are common for recomp and recovery |
- Frequency: 1 tablet per day, ideally in the evening
- Monitoring: fasting glucose and HbA1c are the key safety markers
- Storage: cool, dry place away from direct light
Practical Notes
MK 677 effects on GH output build gradually, so short trials rarely show the full picture. It is a research compound and is not intended for human consumption.
MK 677 Stacks
MK 677 is paired with compounds that reinforce muscle fullness, metabolic support and long-term training sustainability. The rows below link to same-brand Dragon Pharma products.
| Combination | Why it is combined |
|---|---|
| LGD 4033 | Lean mass progression with enhanced recovery depth |
| EQ 300 | Appetite support and endurance-driven growth on long cycles |
| L-Carnitine 500 | Recomposition phases balancing conditioning and recovery |
| HCG 2500IU | Bridge phases that emphasize hormonal signaling and stability |
MK 677 Side Effects
MK 677 has a distinctive side effect profile driven by its ghrelin-mimicking action. The most common reports are increased appetite, water retention and a rise in fasting blood sugar, which is why glucose monitoring is a standard part of any protocol.
- Increased appetite and possible weight gain from extra intake
- Water retention and mild swelling, mainly in the hands and feet
- Rise in fasting glucose and HbA1c with longer use
- Carpal tunnel-like numbness or tingling and lethargy
- Reports of gynecomastia exist, though the mechanism is debated
MK 677 (Ibutamoren) is a research compound. It is not approved for human or veterinary use. Keep it away from food, drink and skin contact, and store it out of reach of children.
For research use only. Nothing on this page is medical advice; glucose and hormone monitoring belong in a responsible laboratory protocol.

First package never showed up but the guys handled it fast and sent a reship with no problems. Really appreciated that. MK-677 has been great so far too, sleep and recovery feel way better.

“MK-677 is legit. Sleep crazy good, always hungry lol. Package came way faster than I expected too. Definitely ordering again.”
What is MK 677 (Ibutamoren)?
MK 677, or Ibutamoren, is an orally active growth hormone secretagogue that mimics ghrelin and raises natural GH pulse amplitude. Dragon Pharma produces it in 25 mg tablet form for research.
Is MK 677 a SARM or a peptide?
Neither in the strict sense. MK 677 is a small-molecule ghrelin mimetic that is often grouped with research peptides because of its GH-IGF-1 pathway, but it is taken orally and is not a peptide chain.
What does MK 677 do?
Research use centers on the GH-IGF-1 axis: deeper sleep, improved recovery between sessions, a fuller muscle look and appetite regulation. Effects build gradually over weeks rather than days.
How much MK 677 should I take per day?
The most cited research references are 10-25 mg once daily, usually in the evening. Beginners commonly start near 10-15 mg to assess appetite and glucose response before increasing.
How long does MK 677 take to work?
Sleep and appetite changes are often noticed within the first week, while visible body composition changes are more commonly reported after 6-8 weeks of consistent use with proper training and nutrition.
Does MK 677 raise blood sugar?
Yes, increased fasting glucose and HbA1c are the most important safety markers for MK 677. Individuals with diabetes or insulin resistance, and anyone combining it with other glucose-raising agents, should monitor carefully.
Does MK 677 cause water retention and weight gain?
Mild water retention and swelling, especially in the hands and feet, are common, and appetite increase can cause real weight gain if intake is not controlled. Both usually reverse after stopping.
What are the side effects of MK 677?
The most reported effects are increased appetite, water retention, elevated blood sugar, carpal tunnel-like tingling and lethargy. Long-term safety data remain incomplete, and the effects fade when use stops.
Do MK 677 results last after stopping?
Because MK 677 works by amplifying natural GH signaling rather than adding exogenous hormone, its effects wear off after discontinuation. Maintaining the gains depends on training, diet and recovery habits.
Can MK 677 cause gynecomastia?
There are reports of breast tissue tenderness or growth with MK 677, but the mechanism is debated and it does not aromatize to estrogen. Anyone who notices such changes should stop and investigate other causes.
