Nutrobal (MK677)

Also known as Ibutamoren and MK-677, nutrobal is a selective agonist of the ghrelin receptors (SAGR), which is classified as a growth hormone secretagogue (HGH-S). In spite of being associated with SARMS, Nutrobal is actually not a SARM (selective androgen receptor modulator). Yet, it is popularly used in stacks with other SARMS.

Advantages over peptides and exogenous growth hormone

Nutrobal is still in the development stages for treating reduced levels of growth hormone and IGF-1 (insulin-like growth factor 1), especially in children and the elderly.

Overall, the idea is similar to the way GHRP's (growth hormone releasing peptides) work, but without the risk of buying fake or bunk peptides, since it is estimated that over 95% of the peptide market is selling dishonest products. This happens because the peptide market is unregulated, so anyone can sell fake products and easily get away with it.

In addition, human growth hormone (HGH) is extremely expensive to produce, making it very expensive to purchase even with health insurance. As a matter of fact, due to the high cost of HGH many people with legitimate health issues will choose to buy generic growth hormone from China, which is usually underdosed or fake, but considerably cheaper. In many cases HGH from China contains HCG, IGF-1 or in the worst cases mercury and arsenic.

How it Works

Nutrobal (mk677) works by mimicking the growth hormone stimulating action of the endogenous peptide hormone ghrelin, which is known as the appetite boosting hormone, since it causes an increase in hunger. What's more, it also plays a major role in regulating energy distribution. Ghrelin is naturally produced in the gastrointestinal tract, functioning as a neuropeptide in the body's CNS (central nervous system).

Furthermore, nutrobal increases GH and IGF-1 without increasing muscle wasting hormones, such as cortisol. However, unlike exogenous GH, nutrobal will not suppress the body's natural production of growth hormone. All in all, it will add good hormones, will not cause their suppression, and will not increase bad hormones.

Finally, nutrobal has been shown to alter metabolism of body fat, meaning it can help with obesity, and aid in prevention of type 2 diabetes (decrease chance of diabetes). This is in contrast with HGH injections, which increase the chance for type 2 diabetes 100 fold+.

Athletic uses

Just like with many other compounds that were initially meant for medical purposes, nutrobal gained a lot of popularity among athletes all over the world because of how it works and what it does.

Those seeking to increase appetite and bulk will get outstanding results when they use nutrobal for its hunger increasing abilities. In fact, I have personally dosed it before going to bed, and I have woken up in the middle of the night from a deep sleep, starving for a meal. Therefore, many guys who have trouble keeping on mass because they struggle to get in enough calories and protein will love nutrobal.

Moreover, those looking to put on lean muscle mass without fat, can utilize nutrobal as well, since it is so good at metabolizing body fat. Basically, it will help use fat for energy, instead of burning away your muscle mass. Hence, you could use nutrobal while in a caloric deficit when trying to recomp.

However, the benefits of nutrobal (mk677) do not end there, since it will also increase IGF-1 and growth hormone, which will lead to such positive effects as joint/bone health, improved endurance, overall wellness, and sleeping harder at night. As a result, you see many athletes saying that within days of using nutrobal they tend to have more energy simply because they sleep so well on it.

Stacking

Nutrobal can be ran solo at 10-50 milligrams (mgs) per day. Another option would be combining it for added benefits with a SARMS stack, or as part of an anabolic steroid cycle.

Example 12 week Nutrobal run.

Week 1-6

• Nutrobal 25mgs/ed
• Cardarine 20mgs/ed
• Andarine (s4) 25mgs/ed
• N2Guard 7caps/ed

Week 7-12

• Nutrobal 50mgs/ed
• Cardarine 20mgs/ed
• Andarine (s4) 50mgs/ed (split dose am/pm)
• HCGenerate 5caps/ed
• N2Guard 7caps/ed

PCT or bridge

After a steroid cycle, post cycle therapy (PCT) and bridging is important. You must recover your HPTA functions and keep the gains made on cycle. Luckily, implementing nutrobal during this time is a wonderful idea, since it will not interfere with your body's natural recovery of hormones, and it will help you hold onto gains without gaining body fat.

Example Nutrobal (mk-677) PCT (this PCT is for post steroid cycles of 12 weeks or more)

Week 1-3

• Nutrobal 25mgs/ed
• Clomid 50mgs/ed
• Nolvadex 40mgs/ed
• HCGenerate ES 5tabs/ed
• Cardarine 20mgs/ed
• N2Guard 7caps/ed

Week 4-6

• Nutrobal 25mgs/ed
• Clomid 25mgs/ed
• Nolvadex 20mgs/ed
• HCGenerate ES 5tabs/ed
• Cardarine 20mgs/ed
• N2Guard 7caps/ed

Side effects

The beautiful part of nutrobal is that you can run it without the fear of any hormonal suppression. This means your natural testosterone and growth hormone levels will not be effected at all when using nutrobal. Therefore, no PCT is necessary if you are running nutrobal on its own.

As it was mentioned above, nutrobal can make you really hungry, so the the increased food bill is the biggest complaint that users have. In fact, this hunger can get so strong, that you might wake up in the middle of the night to eat something, and many don't like to get their sleep interrupted. Interestingly, I have found that taking the dosage at bed time increases the chances of this happening. Hence, a user who don't want this issue to take place can administer nutrobal earlier during the day (AM time).

Half Life

Nutrobal has a 5-6 hour half life, with the specific IGF-1 effects lasting 24-26 hours. However, it is a myth that you must dose nutrobal multiple times per day for good results - I have had plenty of success dosing it just in the AM before breakfast.

Dosage

Nutrobal is best dosed at 25 mgs per day, taken in the morning before your meal. Then you can dose the same amount again in the early afternoon, or before bedtime. Remember, you still get the IGF-1 benefits even if you dose nutrobal just once per day in the morning.

Where to Find

Nutrobal is currently in development, so it can only be acquired via research chemical sources. Unfortunately, most of the nutrobal being sold has been found to be fake or underdosed. This happens mostly because nutrobal tends to be 100-300% more expensive than SARMS products. Consequently, if you want to avoid being scammed you must be very careful where you get your SARMS products from. Personally, I recommend you to look at SARMS1.com products, as it has been proven in testing that they have the actual compound. I research with them all the time.

Female use

There has not been a lot of interest with nutrobal in the female fitness world yet, as many women choose to go with the purely anabolic SARMS instead of the more advanced nutrobal. Those females that are looking for a boost in IGF-1 and growth hormone production can run nutrobal at a light dose of 5mgs per day.
