What Is MK-677 (Ibutamoren)?

MK-677, commonly known as Ibutamoren, is a research compound classified as a growth hormone secretagogue. It works by mimicking the action of ghrelin and binding to ghrelin receptors, stimulating the pituitary gland to increase growth hormone and IGF-1 output.

Unlike injectable GH peptides such as CJC-1295 or Ipamorelin, MK-677 is orally active — making it one of the most widely studied non-peptide GH secretagogues in the research compound category.

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

How Our MK-677 Compares

Frequently Asked Questions — MK-677 (Ibutamoren)

• Is MK-677 legal to buy in the US?

  Yes. MK-677 (Ibutamoren) is legal to purchase in the United States for research purposes. It is not a scheduled controlled substance under the DEA Controlled Substances Act and is not classified alongside anabolic steroids or SARMs currently under legislative review.

  However, MK-677 is not FDA-approved for human consumption, is not legal to sell as a dietary supplement, and cannot be marketed with health or performance claims. It must be purchased strictly for legitimate laboratory or scientific research use. Always verify current regulations in your state before ordering.

• What is MK-677 used for in research?

  MK-677 is studied across several research areas due to its role as an orally active growth hormone secretagogue. Published and ongoing research covers:

  • Growth hormone and IGF-1 stimulation mechanisms
  • Muscle wasting and body composition studies
  • Bone density and skeletal health investigations
  • Sleep quality and REM sleep modulation research
  • Appetite regulation and metabolic rate studies
  • Cognitive function and neuroprotection research in aging models

  All research use must comply with applicable institutional and regulatory guidelines. MK-677 is not approved for any therapeutic application in humans.

• What is the difference between MK-677 solution and MK-677 powder?

  Both formats contain the same compound — MK-677 (Ibutamoren Mesylate) — at verified purity. The difference is in preparation and application:

  • Solution (25mg/ml in 50ml): Pre-measured and ready to use immediately in research protocols. No preparation required. Ideal for standard dosing studies and consistent administration.
  • Powder (1g): Raw material in lyophilized form. Suited for researchers who need to formulate custom concentrations, prepare capsules, or conduct studies requiring precise gravimetric measurement.

  Both are independently tested and come with a Certificate of Analysis confirming identity and purity.

• How do I verify the purity of your MK-677?

  Every batch of MK-677 we stock has a corresponding Certificate of Analysis (COA) issued by an independent, US-accredited third-party laboratory. No in-house testing. No recycled documents.

  Each COA includes:

  • HPLC purity percentage confirming compound concentration
  • Mass spectrometry identity verification matching the correct molecular weight
  • Batch lot number matching the bottle you receive
  • Laboratory name and contact information for independent verification

  COAs are available for download directly on the product page — no request or account required. If the lot number on your bottle does not match the posted COA, contact us immediately for resolution.

• How fast does MK-677 ship and what are the delivery options?

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

  • Standard shipping: 2–4 business days via USPS or UPS depending on location
  • Express shipping: 1–2 business days, available at checkout
  • Overnight: Available on request for qualifying orders

  All orders ship in plain, discreet packaging with no product labeling visible on the outside. A tracking number is emailed immediately upon dispatch. We ship to all 50 US states. International shipping is not currently available.

• What payment methods are accepted?

  • Credit and debit cards: Visa, Mastercard, American Express — no surcharge
  • Cryptocurrency: Bitcoin, Ethereum, and other major coins accepted
  • eCheck: Bank transfer via eCheck with standard processing time
  • Zelle and Venmo: Available for domestic US orders

  Unlike many research compound vendors, we do not add processing surcharges to card payments. The price you see at checkout is the final price you pay.

• What is the shelf life and storage requirement for MK-677?

  MK-677 solution and powder are stable under proper storage conditions:

  • Solution: Store at room temperature (15–25°C / 59–77°F), away from direct sunlight and heat. Stable for up to 24 months when stored correctly. Do not refrigerate unless instructed by your specific research protocol.
  • Powder: Store in a cool, dry environment away from light and moisture. When kept sealed and away from humidity, powder form typically maintains stability for 24–36 months.

  All bottles ship with a manufacturing date and expiry date printed on the label. Do not use after the expiry date stated on the COA or label.

• Can I buy MK-677 in bulk quantities?

  Yes. Bulk and wholesale pricing is available for research institutions, laboratories, and verified researchers requiring larger quantities. Bulk orders are available for both the solution and powder formats.

  Volume discount tiers apply automatically at checkout for qualifying order sizes. For institutional purchase orders, custom invoicing, or quantities above standard catalog levels, contact us directly via the enquiry form with:

  • Your required quantity and format (solution or powder)
  • Intended research application or institutional affiliation
  • Preferred delivery timeline

  All bulk orders include full COA documentation and are subject to the same third-party verification standards as single-unit purchases.
