What is Pumping Iron MK-677?
Pumping Iron MK-677 (Ibutamoren Mesylate) is a growth hormone secretagogue best known for its abilities to support muscle gain and fat loss. This makes it popular for dieting, bulking, or body recomposition.
Research shows Ibutamoren has a list of benefits (aside from muscle gain and fat loss), all associated with its ability to increase HGH and IGF-1 levels. It increases growth hormone levels with no increase in cortisol, which will be of major interest to anyone with serious physique goals.
We recommend running Pumping Iron MK-677 on a long-term basis to support best results (for 3-6 months as a staple in your supplement regime).
How MK-677 Works
Pumping Iron MK677 increases growth hormone levels by mimicking the action of the hormone ghrelin and binding to one of the ghrelin receptors (GHSR) in the brain.
Ibutamoren has a long list of benefits which will interest anyone who trains – from building muscle and helping with fat loss to increasing your training performance so you can see better results. It increases your body’s IGF-1 and HGH levels so you can reach long term goals.
For muscle gain, fat loss, training endurance, joint and soft tissue repair.
Combined with the appropriate diet and exercise regimen, Pumping Iron MK-677 will effectively increase muscle protein synthesis alongside much improved fat loss, as well as rapid recovery.
Why Use Pumping Iron MK677?
Pumping Iron MK677 is great for supporting a lean bulk, or for a cutting diet or body recomposition. It helps with muscle gain, enhances fat loss, and speeds up healing and injury repair, plus boosts your training endurance. It is also a good choice as a bridge between prohormone cycles.
MK-677 is Not a SARM
MK-677 is not a SARM (selective androgen receptor modulator). It is a compound that encourages secretion of HGH and IGF-1, by imitating ghrelin and binding to ghrelin receptors (GHSR) in the brain. So it can boost the important anabolic hormones IGF-1 and HGH, without disturbing other hormones (like testosterone or cortisol).
These results have been noted at doses from just 5mg up to 30mg per day.
One human study on males showed significant increases in muscle mass and IGF-1 increases (of around 40%) in just two months on MK-677 treatment.
Results to Expect From Pumping Iron MK-677
MK-677 was developed with the aim of combating such conditions as muscle wasting, obesity and osteoporosis. This makes it an ideal candidate compound for researchers working on the effects of Grown Hormone levels and associated changes in physiology, muscle mass and changes to body mass index.
The administration of MK-677 within test subjects can stimulate significant changes in Muscle Mass and density. MK-677 will also greatly increase the appetite of any test subject. As MK-677 acts as a GHS, it is non-suppressive. This means that suitable research projects can extend from a period of 30 days to 1 year. One added benefit is MK-677’s ability to greatly improve sleep quality, which ultimately boosts recovery.
One human study shows impressive results in a group of males given MK-677, showing a significant increase in lean muscle mass in just two months. That same study showed that serum IGF-I increased by approximately 40% with Ibutamoren MK-677 treatment.
10 Benefits of Pumping Iron MK-677
- Increases your levels of IGF-1 and HGH serum
- Boosts lean muscle mass growth
- Supports better fat oxidation
- Promotes faster recovery from training
- Supports good joint health and the healing of skeletal and connective tissue
- Increases bone density
- Tightens skin for more aesthetic skin texture
- Improves sleep quality and sleep depth
- Ideally used long term (minimum 3-6 months) for best results
- Stacks well with any other supplements including SARMs and prohormones
MK-677 is Safe for Women
Ibutamoren doesn’t affect the amount of testosterone or oestrogen the body produces, so it is safe for women and men. There is no risk of specific hormonal imbalances and unwanted side-effects like hair loss, gynecomastia or aggression.
How to Use Pumping Iron MK677
The half-life of Pumping Iron MK-677 is 24 hours so you can take your daily dose once per day.
Ibutamoren is usually taken at 25mg per day but it works well at lower doses. Even 5-10mg is enough to produce numerous GH pulses over the day. Remember, a higher dose comes with more of those side-effects mentioned above.
Some users have reported more pronounced effects at higher doses of around the 25mg range but there is significant anecdotal evidence to suggest a higher dose comes with more side-effects such as lethargy and increase in appetite.
Whether you take MK-677 in the morning or before bed is down to personal preference. Some people prefer pre-bed to avoid some of the side effects such as lethargy but may disrupt sleep if the user experiences hunger pangs.
Some people find that taken first thing in the morning will improve sleep quality but may experience more lethargy during the day. These side effects are dose-dependent. Ultimately you can experiment and find what works best for you.
MK-677 is safe to use for both men and women as it doesn’t affect the amount of testosterone or estrogen the body produces. This means that there is zero-risk of specific hormonal imbalances and unwanted side-effects like puffy nipples, heightened aggression or hair loss.

Pumping Iron MK677 stacks well with anything and is a popular compound to stack with SARMS and prohormones. MK-677 enhances the effects of the SARMs you stack with it. It is commonly stacked with Cardarine, SR-9009 and a Glucose Disposal Agent for rapid fat loss.
Pumping Iron MK677 Side Effects
The most common side-effects with Ibutamoren are slight lethargy and increased appetite, although this isn’t always bad! If you take your dose at night, the lethargy won’t be a problem (and could even help you sleep). And if you are a hard-gainer, you might welcome the appetite boost.
