What Is Chemyo MK677? Full Product Breakdown
Chemyo MK677 is a liquid solution of MK-677 (Ibutamoren mesylate) at a concentration of 25mg per millilitre in a 50ml bottle — giving a total of 1,250mg per bottle. This is Chemyo’s standard liquid format. They sell all their SARMs in 50ml bottles rather than the industry-standard 30ml, which is their most prominent value differentiator. The solution is sold as a research chemical for laboratory use only.
Chemyo MK677 is tested under batch code BA2183, with publicly posted FTIR-HPLC results and concentration data across multiple batches (#1 through #9). The COA is accessible on their website without a login. This level of documentation transparency is what has made Chemyo MK677 a reference point for quality in the research chemical market since 2017.

What Is MK-677 (Ibutamoren)? The Science Behind Chemyo MK677
Before evaluating Chemyo MK677 specifically, it helps to understand why MK-677 generates so much research interest. MK-677 — also known as Ibutamoren or Ibutamoren mesylate — is a non-peptide, orally active ghrelin receptor agonist and growth hormone secretagogue. It is the only compound in this class that can be taken orally with over 60% bioavailability, which is a significant practical advantage over injectable growth hormone peptides.
MK-677 raises GH and IGF-1 levels through four complementary mechanisms, as confirmed by forensic science research published in ScienceDirect (2025):
- Increases production of GHRH (Growth Hormone-Releasing Hormone) — the primary stimulus for GH secretion from the pituitary
- Reduces somatostatin — the hormone that inhibits GH release, effectively removing the brake
- Promotes GHRH signals in the pituitary gland — amplifying the upstream stimulus
- Restrains somatostatin receptor signals — preventing the inhibitory feedback loop from re-engaging
The result: sustained, pulsatile growth hormone secretion without suppressing natural GH production or affecting cortisol at standard research doses. This is the key distinction from exogenous HGH, which suppresses the body’s own GH axis.
What Researchers Use Chemyo MK677 For — Four Documented Research Areas
The following is for research context only. MK-677 is not approved for human use. All products sold are for laboratory research purposes only.
1. Growth Hormone & IGF-1 Research
MK-677 is the most widely used oral GH secretagogue in research precisely because it reliably elevates both GH and IGF-1 without requiring injection. The Translational Andrology and Urology review confirms ibutamoren synergistically interacts with GHRH and activates L-type Ca2+ channels leading to intracellular calcium increases and protein kinase C activation — a detailed mechanistic profile that makes it valuable as a research model. A double-blind, multicenter study of 563 Alzheimer’s patients receiving MK-677 25mg daily for 12 months (PMID: 19015485 ↗) confirmed robust IGF-1 elevation as the primary measurable pharmacological effect.
2. Muscle Mass & Sarcopenia Research
The Oxford Academic review of growth hormone secretagogues in older subjects confirmed that MK-677 at 25mg daily increased lean body mass and serum IGF-1 while demonstrating only a very mild, clinically non-significant increase in insulin resistance. Shoulder flexion total work decreased in the placebo group but not in the MK-677 group — a meaningful protective effect in models of age-related muscle decline.
3. Bone Density Research
MK-677 stimulates bone turnover in elderly subjects based on measurable elevations in biochemical markers of both bone resorption and bone formation. This dual-marker elevation suggests active bone remodelling rather than simple breakdown, making it relevant to osteoporosis and fracture recovery research models.
4. Sleep Architecture Research
MK-677 has been observed to significantly increase REM sleep duration in young adults and to improve sleep quality in elderly subjects. Given that natural GH secretion is strongly coupled to deep sleep, this represents a mechanistically coherent downstream effect. Community researchers frequently study MK-677 specifically for this sleep-related GH pulse enhancement.

Chemyo MK677 Price vs. Alternatives — Value Comparison 2026
One of the most common questions researchers ask after finding Chemyo MK677 is whether the price is competitive. Here is how Chemyo MK677 compares on a per-milligram basis against the market in April 2026:
On a pure per-milligram basis, Chemyo MK677 at $0.064/mg is better value than the 30ml alternatives that charge more per ml. However, the same 50ml volume, same 25mg/ml concentration, and the same independent third-party COA standard is available from us at a lower price point — with the added advantage that our range includes peptides (BPC-157, TB-500, MOTS-c) that Chemyo does not carry.

Chemyo MK677 COA & Lab Testing — What the Documentation Shows
Chemyo MK677 batch BA2183 has three types of documentation publicly posted:
- FTIR Results (BA2183 MK677 FTIR-HPLC Results): Fourier-Transform Infrared Spectroscopy confirms the identity of the compound by matching its molecular fingerprint against a reference standard. This confirms you are receiving MK-677 and not a cheaper substitute.
- HPLC Purity: High-Performance Liquid Chromatography confirms the purity percentage. Chemyo MK677 is tested to 99%+ on this metric.
- Concentration testing (BA2183 #1-#9): Nine separate concentration tests across multiple sub-batches confirm that the actual concentration in solution matches the labelled 25mg/ml. This is the test most suppliers skip — and the one that matters most for research reproducibility.
Chemyo MK677 Reviews — What Customers Actually Say in 2026
Chemyo MK677 has accumulated 229 verified reviews with a 4.9-star average. Recent verified reviews from April 2026 include:
- “Everything went smoothly and quickly” — Damian, April 2026
- “Breakthrough quality!” — Keitan, February 2026
- “Chemyo has first rate service and top notch products” — Paul A., February 2026
- “Genuine MK-677. Good price for 50ml. Will be a returning customer.” — Michael, January 2026
- “Good product as advertised. Concentration accurate.” — Verified buyer, January 2026
The consistent themes across Chemyo MK677 reviews are: fast shipping, accurate concentration, and clean product. The one criticism that appears occasionally is price — one January 2026 reviewer noted “The product is great! Very Pricy.” This is the honest tension with Chemyo MK677: it is a high-quality product, but it is not the most price-competitive option per milligram in the 2026 market.
Is Chemyo MK677 Legal? Regulatory & WADA Status 2026
MK-677 is legal to purchase in the USA as a research-use-only (RUO) compound. Chemyo MK677 — like all MK-677 sold online — is sold under this classification. It is not FDA-approved for any medical indication and is not for human consumption.
WADA status: MK-677 is listed on the WADA 2025/2026 prohibited list under S2.2.4 Growth Hormone Releasing Factors — prohibited at all times, both in and out of competition. This was confirmed by a 2025 ScienceDirect forensic science publication that noted MK-677 increases IGF-1 and growth hormone levels which leads to a reduction of body fat, increasing muscle strength and muscle mass, and is therefore prohibited under WADA S2.2.4. Source: ScienceDirect (2025) ↗
Competitive athletes in any WADA-tested sport cannot use MK-677, including Chemyo MK677. Any researcher or athlete in a tested sport should be aware that MK-677 is detectable in hair samples for extended periods, as documented in the same 2025 forensic study.

Chemyo MK677 — Frequently Asked Questions
What concentration is Chemyo MK677?
Chemyo MK677 is formulated at 25mg per millilitre in a 50ml bottle, giving 1,250mg total per bottle. This is the standard research concentration for MK-677 liquid solutions and allows precise volume-based dosing with the included 1ml graduated pipette.
What batch is the current Chemyo MK677?
As of April 2026, the current Chemyo MK677 batch is BA2183, with FTIR-HPLC results and nine separate concentration tests (#1 through #9) publicly posted on Chemyo’s website. You can verify these results at chemyo.com/mk677 before ordering.
Is Chemyo MK677 real or fake?
Chemyo MK677 is genuine. Their FTIR identity testing and HPLC purity documentation under batch BA2183 confirms the compound is authentic MK-677 at the stated concentration and purity. The 229 verified reviews with a 4.9-star average over multiple years further support this. Independent community testing of Chemyo products has consistently matched their posted COA results.
What is Chemyo MK677 used for in research?
Chemyo MK677 is used for laboratory research into growth hormone secretion, IGF-1 elevation, lean mass and bone density research, and sleep architecture studies. MK-677’s oral bioavailability over 60% and non-suppressive mechanism make it one of the most practical GH secretagogues for research models. It is not approved for human consumption and is sold for research purposes only.
How does Chemyo MK677 compare to injectable GH peptides like CJC-1295?
Chemyo MK677 (ibutamoren) and CJC-1295/Ipamorelin both stimulate GH release but through different pathways. MK-677 mimics ghrelin at the ghrelin receptor; CJC-1295 mimics GHRH at the GHRH receptor. MK-677’s key practical advantage is oral bioavailability — no reconstitution or injection required. The tradeoff is that CJC-1295/Ipamorelin produces a sharper GH pulse while MK-677 produces more sustained, lower-amplitude GH elevation. Many research protocols study both compounds to compare these distinct release profiles.
Does Chemyo MK677 suppress testosterone?
No. This is one of MK-677’s key distinguishing features: it does not suppress endogenous testosterone production. MK-677 operates through the ghrelin receptor pathway, not the androgen receptor, so it has no direct effect on the HPTA axis. This is in contrast to SARMs like RAD-140 or LGD-4033, which do suppress testosterone at the research level. Researchers studying GH/IGF-1 elevation without HPTA interference specifically select MK-677 for this reason.
