Ibutamoren is a substance that is associated with more discussions on online forums than actual clinical research. However, the research so far does support several benefits of ibutamoren, associated with its ability to increase growth hormone and IGF-1 levels. Read on to find out what these benefits are, whether ibutamoren can help you, and how to deal with potential side effects.

Ibutamoren is frequently discussed on online forums for its anabolic muscle-building properties. It is available over the counter and used by those wishing to increase their growth hormone levels.
However, clinical studies of this compound are relatively few. In the text below, we will highlight what is known about ibutamoren so far.
Ibutamoren increases growth hormone levels, by mimicking the action of the hormone ghrelin (R), and binding to one of the ghrelin receptors (GHSR) in the brain (R). Activated GHSR stimulates growth hormone release from the brain.
GHSR is found in brain regions that control appetite, pleasure, mood, biological rhythms, memory, and cognition (R). Therefore, we can expect that ibutamoren may also affect these functions. However, so far, clinical studies describe only the effects ibutamoren has on appetite – and as expected, like ghrelin, ibutamoren increases it.
A great thing about ibutamoren is that it increases growth hormone levels with little or no increase in other hormones, such as cortisol (R, R). Cortisol suppresses the immune system, reduces wound healing, and impairs learning and memory, and it’s usually not good to have this hormone elevated.
Benefits of Ibutamoren
1) Ibutamoren Helps Build Muscles
Ibutamoren is frequently used as an anabolic substance, to increase lean body mass i.e. create bigger muscles. It is orally active and can be taken once a day. These are all benefits compared with other growth hormone stimulators.
2) Ibutamoren Reduce Muscle Wasting
In food-deprived healthy volunteers, ibutamoren reversed diet-induced protein loss (R), that could cause muscle wasting.
In elderly patients with hip fracture, ibutamoren improved gait speed, muscle strength and reduced the number of falls (R).
3) Ibutamoren Increases Bone Density
Growth hormone (GH) increases bone turnover and eventually bone density (R). However, because of the increased turnover in subjects treated with growth hormone, bone density can initially decrease before increasing (R). Basically, it takes time (> 1 year) to see the bone density increase.
4) Ibutamoren Improves Sleep
Apart from scientific studies, there have been many reports of subjective improvements in sleep quality, across various online forums.
5) Ibutamoren Combats Aging and May Increase Longevity
Growth Hormone (GH) secretion and muscle mass both decline from mid-puberty throughout life (R).
In a study in the elderly, daily ibutamoren increased GH and IGF-1 levels to those of healthy young adults without serious adverse effects (R). IGF-1 is known to have beneficial effects on longevity (R, R).
6) Ibutamoren May Have Nootropic Effects
Some people use ibutamoren as a nootropic because it acts on the ghrelin receptor, which has nootropic effects. You can read more about these effects in the post on ghrelin. Science is, however, yet to study if and how ibutamoren affects cognitive performance.
Two indirect mechanisms by which ibutamoren can improve brain function:
- Ibutamoren increases IGF-1, which is known to improve memory and learning (R, R, R).
- Ibutamoren also increases REM sleep duration and sleep quality (R). And we know that sleep is essential for good cognitive function (R).
A study questioned the association of low IGF-1 and Alzheimer’s disease, and whether ibutamoren could be of help. However, in this study, ibutamoren was ineffective at slowing the progression of Alzheimer’s in humans (R).
7) Ibutamoren is Beneficial in Treating Growth Hormone Deficiency
Ibutamoren can increase growth hormone, IGF-1, and IGFBP-3 levels in children with growth hormone deficiency (R). Furthermore, these effects are achieved without changing the concentrations of prolactin, glucose, triiodothyronine (T3), thyroxine (T4), thyrotropin, cortisol or insulin (R).
8) Ibutamoren May Help with Wound Healing and Tissue Regeneration
There are individual reports of ibutamoren being helpful, but scientific studies are lacking.
9) Ibutamoren May Help with Hangovers
This one is anecdotal, but people report curing hangovers with ibutamoren.
Although most studies report little or no side effects, one study was terminated because of serious adverse events. In elderly patients with hip fracture, ibutamoren elevated blood pressure, blood glucose and HbA1c, and there were cases of congestive heart failure (R). The patients experiencing congestive heart failure were over 80 and had a history of prior heart failure.
It would be prudent to watch your carbohydrate intake and regularly check blood sugar and insulin levels while taking ibutamoren.
As an anabolic, ibutamoren should be avoided if you have cancer. Both growth hormone and IGF-1 may promote cancer growth.
I would not take Ibutamoren if you are Th1 dominant, since growth hormone has immune stimulatory properties.
Genetics Affecting Responses to Ibutamoren
SelfDecode is the best and most powerful genetic application, which will help you interpret your genes. Sign up and upload your raw data to see what versions of these genes (alleles) you have. Sign up for 23andme for only $99 and put your raw data into SelfDecode.
GHSR is the gene that codes for the ghrelin receptor. When this receptor is activated by ghrelin or ibutamoren, the pituitary gland is given the signal to start releasing growth hormone. It’s better to have this gene increased most of the time.
