WHAT IS MK-677?
MK-677 (also known as Ibutamoren, Nutrobal and Oratrope) is an oral Growth Hormone Secretagogue and an agonist of the Ghrelin Receptor. It was developed by Reverse Pharmacology for the treatment of growth hormone deficiency, muscle wasting conditions, and osteoporosis.
This is an extremely popular compound used as a replacement for regular HGH injections. It is not as powerful as elevated doses of HGH, but it is way cheaper, rarely faked, and orally bioavailable. This is a versatile PED that can be added to pretty much any cycle, whether you are cutting, bulking, maintaining or just trying to recover from an injury.
Often misinterpreted, MK-677 is NOT a SARM but a secretagogue, similar to a Growth Hormone Releasing Peptide (GHRP) like GHRP-2, GHRP-6, Ipamorelin, and Hexarelin. Many just put this chemical under the umbrella class of SARMs as it can be used synergistically with practically any SARM, AAS (Steroid), or other PED (performance enhancing drug) on the market.

MK-677 (IBUTAMOREN) HISTORY
In 2017, Ammonett Pharma LLC receives a US patent to proceed with their brand drug Oratrope, a pill-form MK-677 [R].
In 2018, Lumos Pharma acquired the license for Ibutamoren (MK-677) [R]; they then referred to the compound as LUM-201.
Growth Hormone DeficiencIES
MK-677 is currently under investigation for the treatment of human growth hormone, growth hormone deficiency and deficiency and frailty in the elderly [R].
HOW DOES MK-677 WORK?
Growth Hormone Secretagogue
MK-677 works by activating the ghrelin receptor with IGF-1 feedback preventing excess GH production. Increased levels of GH stimulates protein synthesis to accelerate muscle growth and bone density.
BROSCIENCE TIP
It may be possible to enhance the effects of MK-677 by using Huperzine A. According to some “broscientists”, it can inhibit somatostatin, a hormone that limits both GH levels and growth hormone production, allowing MK-677 to increase GH levels and increase growth hormone levels even more. There is no scientific data to prove that Huperzine A can actually do this, but there are anecdotal reports from people who experienced a noticeable increase in growth hormone levels and the intensity of Ibutamoren’s effects after introducing Huperzine A at 250 micrograms a day (more tips like this can be found in our guide towards the bottom of this page).

MK-677 BENEFITS
While more serious clinical trials and clinical research that is underway with MK-677 benefits and side-effects, we’ve compiled A LOT (thousands) of responses and blood panels from our community to come up with a semi-exhaustive list for you.
MUSCLE GROWTH
STRENGTH AND PERFORMANCE
FAT LOSS
Growth Hormone is known for boosting fat loss through lipolysis (mobilization of fat for energy), so you can expect the same to occur with MK-677 [R]. Unfortunately, it will make you hungry, so you may struggle to remain on a calorie deficit.
If you intend to use MK-677 for fat loss, I would suggest taking it before bed at least 3 hours after your last meal, followed by 3-4 hours of fasting after you wake up the next day.
BONE DENSITY & JOINT STRENGTH
RECOVERY AND HEALING
INCREASED HUNGER
BETTER SLEEP
The sleep improvement caused by Ibutamoren is one of its best properties. You can expect REM sleep to be deeper and last for longer, and you will almost certainly wake up more refreshed and energized the next morning [R].
According to some people, 6 hours of sleep on Ibutamoren are as effective, refreshing and energizing as 8 hours of normal sleep.
This benefit will also contribute to muscle growth, fat loss, muscle building, and injury recovery.
NUTRIENT PARTITIONING
COSMETIC BENEFITS
Unfortunately, MK-677 is not without side-effects and while the list of serious adverse reactions may look as exhaustive as the benefits, most of these side-effects of MK-677 can be mitigated through proper dosing, timing oral administration, food consumption, and supplementation (more on all of this in the On-Cycle Therapy chapter).
INSULIN SENSITIVITY/BLOOD SUGAR LEVELS
WATER RETENTION
INCREASED BLOOD PRESSURE
If you didn’t know, excessive water retention can cause high blood pressure.
LETHARGY
CANCER
MK-677 will NOT cause cancer. However, if a user already has cancer (whether he is aware of it or not), Ibutamoren will speed up the growth and development of his cancer cells [R].
PROLACTIN & OTHER SIDE-EFFECTS
PROLACTIN LEVEL INCREASES

HOW TO AVOID & REVERSE SIDE-EFFECTS
MK-677 DOSAGE FOR BODYBUILDING
Bodybuilders use anywhere from 10mg to 30mg a day of MK-677 but the sweetspot that most male users prefer is 20mg a day.
Female users can get amazing results with as little as 10mg a day, and they should never use more than 20mg a day.
HOW TO CYCLE MK-677
The most common MK-677 dose on a cycle consists of 20mg, split twice a day, taken for a total of 12 weeks or one full dose of MK-677 at 20mg taken at night before bed. The shortest MK-677 cycles are usually around 6 weeks (during a PCT) and the longest ones can last for up to 24 weeks.
MK-677 can be taken anywhere from 6 weeks to 24 weeks at 20mg/day.
We really believe that 20mg a day for 12 weeks is the best approach to using MK-677, since it’s a protocol that allows most people to get amazing results without experiencing seriously nasty side-effects. This allows the user to take it synergistically with a SARM or AAS and finish it with the Post-Cycle Therapy that cycle calls for as well.
MK-677 ON-CYCLE THERAPY
It’s imperative to do your research before administering chemicals like MK-677. While the health benefits outweigh the side-effects in our opinion, there sometimes is a cost to research no matter what you do.
In this section, we’ll discuss many of the side-effects of MK-677 we touched on above and how to mitigate or at least control them.
PREVENTING MK-677 PROLACTIN-INDUCED GYNOCEMASTIA & ERECTILE DYSFUNCTION
As we learned above, increased levels of Prolactin can not only cause gynecomastia but also erectile dysfunction in men [R].
We recommend using Vitamin B6 (P5P form) at 100mg before bed every single day of the cycle. Do this even if you think you are not prone to gyno, as this dose of P5P will not have any negative side-effects and will also have a good impact on overall health and will improve sleep quality too. If B6 does not work, try Cabergoline at 0.25mg every 3 days or Pramipexole at 0.125mg a day.
If sexual dysfunction persists, we recommend having Sildenafil (Viagra) on-hand while your prolactin levels start to decrease from the above supplementation. We’d like to note that vasodilators like Sildenafil or Tadalafil also help reduce blood pressure (effective when water retention is occurring); the very thing Tadalafil was designed for (until doctors realized it greatly improved sexual function).
INCREASING INSULIN SENSITIVTY ON MK-677
No one wants to raise their blood sugar levels and for sure no one wants to acquire Type 2 Diabetes. Typically, at-most, only fasted blood sugar levels will be elevated but in case one was predisposed to Type 2 Diabetes or becoming pre-diabetic, we recommend the following protocol for elevated blood pressure first.
The low insulin sensitivity (aka insulin resistance) and high blood sugar levels caused by MK-677 can be mitigated by taking 2 days off every week. For example, you can take MK-677 from Monday to Friday, stay off it during the weekend, and then resuming its use the next Monday. Alternatively, you can do 4 weeks on 1 week off.
If you do not want to take breaks, you can fight this side-effect by supplementing with Berberine (or a more advanced glucose disposal agent) at 300 to 500mg before a carbohydrate-heavy meal.
Alternatively, you can use Ashwagandha (250-500mg 2-3 times a day), Chromium Picolinate (200 micrograms 3 times a day) or Cinnamon Bark (600mg twice a day). Timing these supplements before carb-loaded meals is key for optimal results.
If you are using Ibutamoren on a calorie deficit for the purpose of losing fat, you can do intermittent fasting and/or decrease your carbohydrate intake to achieve better results while also keeping insulin resistance and high blood sugar in check.
MK-677 TL:DR
In a nutshell, we could say that MK-677 is an incredibly effective research chemical that will not only by itself effectively build up lean body mass and muscle mass and improve recovery but synergistically stack with any SARM or AAS to optimize progress even further.
WHERE TO BUY MK-677
If you’ve decided to research with MK-677 and want to find the best MK677 for sale, choosing a reliable company to buy from is crucial, since buying it from a bad company could result in you getting no results or getting horrible side-effects due to being sold something that’s not actually MK-677.
