- 0:00So if you're a Mormon AKA MK-677, I have some decent experience with this.
- 0:06It's a pretty good compound.
- 0:07It's only good if you're really bad at eating.
- 0:10I would only use this compound in a surplus because if you're in a deficit and you take
- 0:15this throughout the day, there's literally no way you're going to be able to hold yourself
- 0:18back because what it does, it increases the amount of growling in your body.
- 0:23So it's going to make you hungriest fuck because that's basically the form of that allows you
- 0:28to, that makes you hungry.
- 0:31So when you take it, it's going to increase that and you're going to fucking feel, you're
- 0:36going to feel so hungry.
- 0:38So that's why I only say the only way I would ever recommend it to people is if you're genuinely
- 0:43really fucking bad at eating to the point where you literally can't eat to save your life.
- 0:51If you can't eat to save your life, then maybe try some MK.
- 0:54Obviously, if you're old enough, but what else it does man, also a lot of people think it's
- 0:59a sarm.
- 1:00It's not a sarm.
- 1:01It's not a sarm.
- 1:02It's a growth hormone, it's a crita gog.
- 1:03So what it does is it tells your pituitary gland to release more IGF-1 and growth hormone.
- 1:08So obviously you're going to have some better fullness.
- 1:11You're going to recover better.
- 1:12You're going to have some better sleep.
- 1:13All the good effects that come with GH, you're going to get a little bit of that from MK.
- 1:17There's some downsides.
- 1:19A lot of guys have to watch their blood sugar because it affects their insulin sensitivity.
- 1:23That's something you have to look out for as well.
- 1:24And you're also going to retain a decent amount of water.
- 1:27Some people just turn into blow lords on MK.
- 1:30So that's not something that you want to risk.
- 1:31I want to recommend it because some guys, like I said, they get super, super puffy from
- 1:36all the water retention.
- 1:37It's looking like super, super puffy looking.
- 1:40So like I said, you also have to watch for your blood sugar.
- 1:43It could raise your blood sugar because it lowers your insulin sensitivity, which isn't
- 1:47good because if you know anything about building muscle, you need good insulin sensitivity.
- 1:52For your body to actually absorb the nutrients that you're giving it with no insulin sensitivity,
- 1:56it's cooked.
- 1:57That's some people just get super puffy and turn into blow lords on MK.
- 2:01So if you don't want that, if you don't want to potentially risk that, then I would recommend
- 2:05it.
- 2:06But it's a good, it's a decent compound.
- 2:08Like I said, it's good for bulking.
- 2:09It's good if you're really, really bad at eating or if you need to add in more food and
- 2:13that's a huge struggle for you if you're already down in five, six meals a day and you have
- 2:18to add in more to get bigger.
- 2:20And you could throw that in to help you out a little bit.
- 2:22But other than that, men, a lot of people think that they're going to hop on MK and blow
- 2:28up overnight, which just isn't the case.
- 2:30It's not that strong.
- 2:31At the end of the day, all it does is it makes you more hungry.
- 2:35And in turn, you being more hungry, you're going to need more food.
- 2:38You're going to get bigger.
- 2:40So.
GymTok peptide claims vs. what research actually shows
Quick answer
MK-677 (ibutamoren) is an oral ghrelin receptor agonist that stimulates pulsatile growth hormone release from the pituitary and secondarily elevates IGF-1. Published human trials confirm its effects on appetite, body composition, and sleep quality, but also document consistent impairment of insulin sensitivity and elevated fasting glucose, making metabolic monitoring essential for any supervised use. It remains an unapproved investigational drug with no established safety profile for long-term use outside of clinical trials.

Page-specific review note
What this exact clip is really saying
This FormBlends review is specific to "GymTok peptide claims vs. what research actually shows" from Dorian Colomvakos. We read the clip as a Peptide social video fact-checks claim about Peptide social video fact-checks, then separate the useful signal from what a short social video cannot prove. The page-specific claim focus is: MK-677 (ibutamoren) is an oral ghrelin receptor agonist that stimulates pulsatile growth hormone release from the pituitary and secondarily elevates IGF-1.
The reason this review is not generic is the source wording and the canonical claim label "peptides replying to charlie gymtok foryoupage gymmotivation gymtrans." In this clip, the useful excerpt is: "So if you're a Mormon AKA MK-677, I have some decent experience with this." That wording changes the review because it points to Peptide social video fact-checks evidence, safety, and patient-fit context, not a one-size-fits-all protocol.
The source trail for this page is checked against Ipamorelin, the first selective growth hormone secretagogue (1998), The growth hormone secretagogue ipamorelin counteracts glucocorticoid-induced decrease in bone formation (2001), and Influence of chronic treatment with the growth hormone secretagogue Ipamorelin (2002), plus the creator's own wording. Peptide social video fact-checks decisions still need an eligibility review, medication-interaction screen, access check, and quality-control review before anyone treats a social clip as medical advice.

What it helps with
- MK-677 (ibutamoren) is an oral ghrelin receptor agonist that stimulates pulsatile growth hormone release from the pituitary and secondarily elevates IGF-1. Published human trials confirm its effects on appetite, body composition, and sleep quality, but also document consistent impairment of insulin sensitivity and elevated fasting glucose, making metabolic monitoring essential for any supervised use. It remains an unapproved investigational drug with no established safety profile for long-term use outside of clinical trials.
- MK-677 is not a SARM. It is a ghrelin receptor agonist that stimulates pulsatile GH release from the pituitary, a pharmacologically distinct mechanism.
- Svensson et al. (2000) confirmed in a randomized controlled trial that MK-677 significantly increases appetite and caloric intake in healthy adults, supporting the creator's core use case.
What it may miss
- It may not cover eligibility, contraindications, medication interactions, lab history, or dose escalation.
- Compound access, legal status, and product quality still need a separate safety check.
- Social video captions rarely show the full evidence base behind a claim.
Best next step
Compare the claim against a FormBlends guide, safety page, and licensed-provider review before acting.

- Svensson et al. (2000) confirmed in a randomized controlled trial that MK-677 significantly increases appetite and caloric intake in healthy adults, supporting the creator's core use case.
- Murphy et al. (1998) documented reduced insulin sensitivity and elevated fasting glucose in humans after two months of MK-677 use. This is a real metabolic risk, not a minor side effect.
- MK-677 is not FDA-approved for any indication and is classified as an investigational drug. It is not a dietary supplement regardless of how it is marketed online.
- Water retention linked to secondary aldosterone increases is a documented and common side effect, and can meaningfully obscure body composition progress during a bulk.
- Baseline and follow-up bloodwork including fasting glucose, HbA1c, and IGF-1 levels is essential for anyone using this compound under medical supervision.
- The creator's framing as a modest appetite tool rather than a transformation compound is more honest than most GymTok MK-677 content, but this is still an unregulated investigational drug being discussed without medical context.
Our take · Written by FormBlends editorial team · Reviewed by FormBlends Medical Team · This is not a transcript. It is our independent review of the video above.
What did @doriancolom actually say?
The creator made a handful of claims worth examining. He said MK-677 is not a SARM, that it works by stimulating the pituitary to release more growth hormone and IGF-1, that it makes you intensely hungry, and that it lowers insulin sensitivity. He also said it causes water retention in some users and that he would only recommend it to people who genuinely struggle to eat enough. He framed it as a modest compound, not a transformation drug.
That framing is actually more responsible than most MK-677 content on GymTok, which tends to oversell it. He was direct about the downsides and did not claim it builds muscle on its own. A few of his mechanistic explanations need some correction, though.
Does the science back this up?
Mostly yes, with one notable error in how he explained the hunger mechanism. MK-677 is a ghrelin mimetic and a growth hormone secretagogue, not a direct growth hormone or IGF-1 analog. It binds to ghrelin receptors (GHSR-1a) and triggers the pituitary to pulse growth hormone, which then drives IGF-1 production in the liver. That part he got right.
The hunger claim is well-supported. Ghrelin is sometimes called the "hunger hormone," and MK-677's agonism at ghrelin receptors does produce significant appetite stimulation. A randomized controlled trial by Svensson et al. (2000, Journal of Clinical Endocrinology and Metabolism) confirmed that MK-677 administration increased appetite and food intake in healthy adults. That tracks with what the creator described.
On insulin sensitivity: the evidence is real. Murphy et al. (1998, Journal of Clinical Endocrinology and Metabolism) found that MK-677 increased fasting blood glucose and reduced insulin sensitivity in older adults after two months of use. This is a legitimate metabolic concern, not a minor footnote.
What did they get wrong (or right)?
He said MK-677 "increases the amount of growling in your body," which appears to be a mangled attempt at saying it increases ghrelin. To be precise: MK-677 does not necessarily increase circulating ghrelin levels. It mimics ghrelin by activating the same receptor. That is a mechanistic difference that matters if you are trying to understand what the compound actually does.
He also got the insulin sensitivity direction slightly confused mid-video. He said it "lowers your insulin sensitivity" and separately said "it could raise your blood sugar because it lowers your insulin sensitivity." Both of those statements point in the same direction, so the logic is internally consistent, but the way he worded it made it sound circular. The core warning is accurate: reduced insulin sensitivity can impair muscle nutrient uptake and raises metabolic risk, particularly for people with pre-diabetes or a family history of type 2 diabetes.
What he got right: the classification correction. MK-677 is not a SARM. It is not a selective androgen receptor modulator. Calling it a growth hormone secretagogue is accurate. That distinction matters legally and physiologically.
What should you actually know?
MK-677 is an investigational compound. It has never been approved by the FDA for any indication. It is not a supplement, despite being sold that way in many online markets. Research by Nass et al. (2008, Journal of Clinical Endocrinology and Metabolism) showed it increased IGF-1 and growth hormone in older adults, but the same study noted elevated fasting glucose as a consistent side effect across the study population.
The water retention the creator describes is real and tied to increased aldosterone activity secondary to GH elevation. Some users retain several pounds of fluid, which can obscure body composition changes and affect blood pressure.
The creator's advice to only use it during a caloric surplus is pragmatically reasonable given the appetite stimulation, but it is not a clinical recommendation. Anyone considering MK-677 should have baseline bloodwork including fasting glucose, HbA1c, and IGF-1 levels, and should be monitored by a licensed clinician. This is not a compound to experiment with casually based on a TikTok video, including this one.
