MK-677: My 3-Month Journey to Bigger Gains and Better Sleep
Written by: Leo Martin
Last Updated: October 27, 2025
If you're curious about MK-677 (Ibutamoren), you're not alone.
Like many, I was intrigued by the promise of increased growth hormone levels, better recovery, and enhanced muscle growth.
After using it consistently for three months, I want to share my honest experience, including the benefits, side effects, and everything in between.
MK-677 from here was my go-to source.
Here’s how it played out for me..
What is MK677?
MK-677, also known as Ibutamoren, is a growth hormone secretagogue. It stimulates the release of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) by mimicking the action of the hormone ghrelin.
Unlike synthetic GH injections, MK-677 does this naturally by increasing your body’s production of GH, which is why many bodybuilders and athletes consider it a valuable tool for gaining muscle, improving recovery, and even enhancing sleep quality.
My MK-677 Experiecne
Weeks 1-4: Noticeable Hunger and Early Gains
I started with a moderate dose of 10 mg per day. The first thing I noticed was a significant increase in hunger. It was almost insatiable, making it challenging to stick to my usual diet. However, this also meant that I could increase my caloric intake, which contributed to some early strength and size gains. My sleep improved noticeably; I slept deeper and woke up more refreshed.
· Dosage: 10 mg daily
· Effects: Increased muscle fullness, water retention, continued strength gains
· Weight Gain: 2 kilograms (mostly lean mass)
Weeks 5-8: Strength and Muscle Gains with Some Bloat
By the second month, the effects became more pronounced. My strength in compound lifts, like bench press and deadlifts, saw a steady increase. My muscles felt fuller, likely due to the enhanced glycogen storage, but I also started noticing some water retention. This made me look a bit bloated, especially around the midsection. Despite the bloat, my overall physique was improving.
· Dosage: 10 mg daily
· Effects: Increased muscle fullness, water retention, continued strength gains
· Weight Gain: 3 kilograms (with some water retention)
Weeks 9-12: Plateau in Gains and Managing Side Effects
In the final month, the rate of muscle and strength gains started to plateau. I was still gaining, but at a slower pace. The bloating continued, which was a bit frustrating as it masked some of the muscle definition I was working towards. I also experienced some lethargy during the day, which I managed by adjusting my dosing time to the evening. This helped improve sleep even further but didn't completely eliminate the daytime sluggishness.
· Dosage: 10 mg daily (shifted to evening)
· Effects: Plateaued gains, persistent bloating, lethargy
· Weight Gain: 1.5 kilograms (mostly muscle with some water)
Side Effects
· Increased Appetite: The hunger was intense, especially in the first few weeks. It’s manageable if you plan your meals, but be prepared for the cravings.
· Water Retention: This was the most noticeable side effect, making it harder to see muscle definition. Keeping sodium intake in check and drinking plenty of water helped but didn’t eliminate it.
· Lethargy: I felt more tired during the day, particularly in the later weeks. Taking MK-677 before bed helped to mitigate this but didn’t eliminate it entirely.
FAQs About MK-677
1. Is MK 677 Safe for Long-Term Use?
MK-677 is generally considered safe when used in moderation, but long-term use can lead to increased insulin resistance and elevated blood sugar levels. Regular blood work is recommended to monitor these factors, especially if you plan on extended cycles.
2. What’s the Best Time to Take MK-677?
I found that taking MK-677 in the evening worked best for me, as it minimized daytime lethargy and improved sleep quality. However, some prefer to take it in the morning to align with their workout schedules. It’s a matter of personal preference and how your body reacts.
3. Can You Stack MK-677 with Other Supplements?
Yes, MK-677 can be stacked with other supplements like SARMs or even traditional anabolic steroids. However, be mindful of the increased appetite and water retention when stacking, as these can exacerbate side effects.
4. How Does MK-677 Compare to HGH?
MK-677 mimics the effects of HGH but does so by stimulating your body’s own GH production rather than introducing synthetic HGH. This makes it a more natural and less invasive option, though it’s not as potent as HGH injections.
5. Is MK-677 Worth It?
If you’re looking for moderate muscle gains, better sleep, and improved recovery without the need for injections, MK-677 is a solid choice. However, it’s not without its downsides, like increased appetite and water retention. Weigh the pros and cons based on your specific goals.
Final Thoughts
MK677 worked well for me, especially in the early stages where I saw quick gains in strength and muscle size. The side effects, while present, were manageable but highlight the importance of dosing carefully and monitoring your body's response.
If you're considering MK-677, here’s where I got mine.
As always, everyone’s experience is different, so start slow and see how your body reacts before committing to a full cycle.
Be safe!
