What Is Ibutamoren (MK-677)?

Ibutamoren, also known by its development code MK-677, is a research compound classified as a non-peptide growth hormone secretagogue. It works by mimicking the action of ghrelin and binding to ghrelin receptors in the brain, stimulating the pituitary gland to increase growth hormone (GH) and insulin-like growth factor 1 (IGF-1) output without directly supplementing exogenous GH.

What distinguishes Ibutamoren from injectable GH peptides such as CJC-1295, Ipamorelin, or GHRP-6 is its oral bioavailability. Ibutamoren is one of the very few GH secretagogues that is active when taken orally — a property that has made it one of the most studied compounds in the GH secretagogue research category. It has progressed through Phase I and Phase II human clinical trials investigating applications in growth hormone deficiency, muscle wasting, and bone density.

All products are sold strictly for laboratory and research purposes only. Ibutamoren (MK-677) is not approved by the FDA for human consumption.

What to Look for When Buying Ibutamoren Online

Not all Ibutamoren for sale online meets research-grade standards. Before purchasing from any supplier, confirm these quality markers are in place.

• Batch-specific Certificate of Analysis
  Every bottle must have a COA from an independent, accredited laboratory tied to the exact batch lot number on your bottle. A generic or undated COA reused across batches is not acceptable verification.
• HPLC and Mass Spectrometry — both required
  HPLC confirms the purity percentage. Mass spectrometry confirms the compound is actually Ibutamoren by matching its molecular weight. Without both, compound identity cannot be confirmed.
• Exact 25mg/ml concentration confirmed
  Underdosed Ibutamoren is a common issue with budget vendors. The COA should confirm the solution tests at the stated concentration, not simply confirm the compound is present.
• US-manufactured and US-shipped
  Domestic sourcing eliminates customs exposure, reduces transit time, and keeps the chain of custody traceable from manufacturer to delivery.
• 50ml bottle — not 30ml
  At identical concentration and pricing, a 50ml bottle delivers 67% more compound than a 30ml bottle. Most budget vendors default to 30ml. Our standard is 50ml.

Ibutamoren For Sale — How Suppliers Compare

When evaluating where to buy Ibutamoren online, the differences between suppliers go well beyond price. Here is how the key quality and service factors compare across the market.

Who Is Searching for Ibutamoren For Sale?

Researchers and buyers sourcing Ibutamoren for sale come from a broad range of scientific and investigative backgrounds including:

• GH secretagogue researchers studying ghrelin receptor agonism mechanisms
• University labs investigating IGF-1 modulation and growth hormone pathways
• Sleep research teams studying GH pulsatility and REM sleep modulation
• Muscle wasting researchers requiring an oral GH secretagogue reference compound
• Longevity researchers tracking GH and IGF-1 biomarker changes over time
• Biohackers running documented oral GH secretagogue self-experimentation protocols

All purchases are for laboratory and research use only. Ibutamoren (MK-677) is not approved by the FDA for human consumption and is not sold as a dietary supplement.

Frequently Asked Questions — Ibutamoren For Sale

• Where can I find legitimate Ibutamoren for sale in the US?

  Legitimate Ibutamoren for sale in the US comes from domestic suppliers who provide independently verified Certificates of Analysis with every batch. The markers of a trustworthy Ibutamoren supplier are:

  • Batch-specific COA from a named, US-accredited third-party laboratory
  • Lot number on the COA matching the lot number printed on your bottle
  • HPLC concentration verification confirming 25mg/ml — not just compound presence
  • Mass spectrometry confirming compound identity as MK-677
  • US-based manufacturing and same-day or next-day domestic fulfillment

  Avoid any vendor who cannot provide a downloadable, batch-specific COA on demand or who lists a testing lab that cannot be independently contacted for verification.

• Is Ibutamoren for sale legally in the United States?

  Yes. Ibutamoren (MK-677) is legal to purchase in the United States for research purposes. It is not a scheduled controlled substance under the DEA Controlled Substances Act. It is not classified as a SARM under current or proposed SARM scheduling legislation — Ibutamoren is a ghrelin receptor agonist, a mechanistically distinct compound class.

  However, Ibutamoren is not FDA-approved for human consumption. It is not legal to sell as a dietary supplement and may not be marketed with health, performance, or therapeutic claims. It must be purchased strictly for legitimate laboratory or scientific research use. Always verify current regulations in your state before ordering.

• What is the difference between Ibutamoren and MK-677?

  Ibutamoren and MK-677 are the same compound — two names for the identical research chemical. The distinction is simply naming convention:

  • MK-677: The development code assigned by Merck during the compound’s original research and development phase. Commonly used in scientific literature and research community discussions.
  • Ibutamoren: The International Nonproprietary Name (INN) assigned to the compound. Used in clinical trial documentation and pharmaceutical contexts.
  • Ibutamoren Mesylate: The full chemical name including the mesylate salt form in which the compound is most commonly formulated for solution stability.

  When searching for Ibutamoren for sale or MK-677 for sale, both terms refer to the same compound. All three names appear on legitimate COA documentation depending on the laboratory’s naming convention.

• How does Ibutamoren differ from injectable GH peptides like CJC-1295 and Ipamorelin?

  Ibutamoren, CJC-1295, and Ipamorelin all stimulate growth hormone release but work through different mechanisms and routes of administration:

  • Ibutamoren (MK-677): A non-peptide ghrelin receptor agonist. Orally bioavailable — does not require injection. Stimulates GH release by mimicking ghrelin signaling. Has a long half-life of approximately 24 hours, producing sustained GH elevation.
  • CJC-1295: A synthetic GHRH (growth hormone releasing hormone) analog. Injectable only. Stimulates GH release via the GHRH receptor pathway. DAC (Drug Affinity Complex) version has a significantly extended half-life of 6–8 days.
  • Ipamorelin: A synthetic GHRP (growth hormone releasing peptide). Injectable only. Stimulates GH release via ghrelin receptors — same receptor family as Ibutamoren but different mechanism. Short half-life of approximately 2 hours.

  The primary research distinction is oral bioavailability. Ibutamoren is one of very few GH secretagogues active via oral administration, making it the reference compound for oral GH secretagogue research.

• What concentration of Ibutamoren is available for sale?

  Our Ibutamoren is available as a 25mg/ml oral solution in a 50ml bottle — delivering 1,250mg of Ibutamoren total per bottle at a verified concentration. This is the standard concentration used across the majority of published Ibutamoren research protocols.

  Ibutamoren powder (1g) is also available for researchers requiring:

  • Custom concentration formulations above or below 25mg/ml
  • Capsule or alternative delivery format preparation
  • Gravimetric measurement for high-precision dosing studies
  • Larger quantities for extended or multi-subject research protocols

  Both formats are independently tested at ≥99% purity and accompanied by a batch-specific Certificate of Analysis confirming compound identity and concentration.

• How fast does Ibutamoren ship after ordering?

  Orders placed before 2pm EST on business days ship the same day. Orders placed after 2pm EST or on weekends ship the next available business day.

  • Standard shipping: 2–4 business days via USPS or UPS depending on destination

• What is the shelf life and storage requirement for Ibutamoren?

  Ibutamoren solution and powder maintain stability under correct storage conditions:

  • Solution (25mg/ml): Store at room temperature (15–25°C / 59–77°F), away from direct sunlight, heat sources, and humidity. Stable for up to 24 months under correct conditions. Refrigeration is not required and may cause precipitation. Keep bottle tightly sealed when not in use.
  • Powder (1g): Store in a cool, dry, dark location in a tightly sealed container away from moisture. Powder form typically maintains stability for 24–36 months under correct storage conditions.

  Each bottle ships with a manufacturing date and expiry date on the label. Do not use the compound beyond the expiry date stated on the label or Certificate of Analysis.
