Description
Researchers weighing an mk 677 buy can review the full specification of this listing from ChemsYo before ordering. MK-677 Ibutamoren Solution is listed in our liquid research solutions catalog at a labeled format of 25mg/ml – 50ml, with composition, CAS number, storage information and available analytical or quality-control documentation set out on this page.
MK 677 Buy Guidance: Comparing a 25mg/ml Ibutamoren Solution
An mk 677 buy decision usually comes down to three figures: concentration, composition and documentation. This Ibutamoren solution is prepared at 2.5% (25mg/ml) in 5% ethanol and 92.5% deionized water, so each 50ml bottle carries a stated concentration rather than a quantity a laboratory has to weigh out before every run. Use the specifications below to compare the exact format and available product specifications with your own protocol requirements. ChemsYo MK677 is listed as a potent, non-peptide ghrelin receptor agonist with a CAS number of 159752-10-0 and a molar mass of 528.662 g/mol. The compound is searched under several names, including Ibutamoren, MK-0677, L-163,191 and Nutrobal, and every figure shown here is taken from the product record rather than estimated. Researchers comparing mk 677 for sale across suppliers can check those figures directly against the batch analysis published below, rather than relying on a summary.

Quality & Research Information
Product information is provided for laboratory research use only and is not intended as medical guidance. Compare the compound name, listed format and quantity with the requirements of your laboratory before ordering. A solution concentration and a bottle volume describe different properties, while a powder listing states the amount of material supplied. Record the exact item selected and review the current price in the cart. Product illustrations identify the catalog item; the label and order details should be checked again when the parcel arrives.

Where to Buy MK677 from ChemsYo
Listings for mk677 for sale vary widely in how much they disclose. Nothing on this page is inferred, and no specification is presented that is not held on record for MK-677 Ibutamoren Solution 25mg/ml – 50ml. Ready to complete your mk 677 buy? Available payment methods are shown at checkout for the order. For laboratory research purposes only. Not intended for human consumption. Research procurement starts with an exact match between the intended material and the item selected. Similar abbreviations can refer to different compounds or formats, so compare the complete name and chemical identifiers rather than relying on a short search term. Check whether the listing is for a powder, solution, suspension, accessory or value pack. If a specification essential to your protocol is unclear, resolve that question with ChemsYo before placing an order.
What is MK-677 (Ibutamoren)?
MK-677 is the shortened form of the development code MK-0677, assigned to the compound also catalogued as ibutamoren and normally supplied as ibutamoren mesylate. Its systematic name is 2-amino-2-methyl-N-[(2R)-1-(1-methanesulfonyl-1,2-dihydrospiro[indole-3,4′-piperidin]-1′-yl)-1-oxo-3-(phenylmethoxy)propan-2-yl]propanamide. Structurally it is a small non-peptide molecule of the spiroindoline class, and pharmacologists classify it as a growth hormone secretagogue: it was originally synthesised as an orally active, non-peptide mimetic of ghrelin, so that the ghrelin receptor GHS-R1a could be investigated with a stable small molecule rather than a peptide ligand. It is neither a SARM nor a peptide. The catalog specifications describe the item offered for laboratory research. They do not establish suitability for a particular experiment, and they are not instructions for human or animal use. A laboratory should determine its own acceptance criteria, handling requirements and measurement procedure. Keep the product name and format together in your procurement records so a later repeat order can be compared with the item originally selected.
MK-677 names, codes and spellings
Few research chemicals collect as many codes as this one. The original MK-0677 is written MK-677 or MK677, while truncated entries such as mk67 and mk 77 are the same string with a digit lost. Transposed forms including mk-777, mk777 and mk 777 are typing errors rather than separate chemicals. Format-led searches such as mk677 liquid and mk677 pills describe how material is presented, not its composition, and no tablet format is offered here. The frequent searches mk peptide and mk 677 peptide are understandable but inaccurate, since ibutamoren is a non-peptide small molecule. Every spelling below points to this same compound:
- mk67
- mk-777
- mk777
- mk 777
- mk677 pills
- mk677 liquid
- mk peptide
- mk 677 peptide
- mk 77
MK-677 formats available
Two formats are stocked. The 1 g ibutamoren powder is the same compound in dry form, weighed and dissolved by the researcher in a vehicle of their own choosing, which suits work where solvent or concentration must be set in-house. Review every component of a research order separately. Product names, pack quantities and solution concentrations can differ even when containers look similar. Compare the current listing with your laboratory requirements, retain the order confirmation, and inspect the delivered container before use. Contact ChemsYo with the order number and item name if anything differs from the confirmed order; do not substitute assumptions based on another supplier’s listing. 1 g ibutamoren powder ChemsYo product information quality control
What is MK-677?
MK-677, or ibutamoren, is a small non-peptide molecule developed under the code MK-0677 and classified as a growth hormone secretagogue. It was synthesised as an orally active mimetic of ghrelin so the GHS-R1a receptor could be studied with a stable small molecule. ChemsYo supplies it for laboratory research only.
Is MK-677 a peptide or a SARM?
Neither. It is frequently searched as mk 677 peptide or mk peptide, but ibutamoren is a spiroindoline small molecule, not a peptide chain, and it does not act at the androgen receptor, so it is not a selective androgen receptor modulator either. It is a non-peptide ghrelin receptor agonist.
Are mk777, mk67 and MK-677 the same thing?
Yes. All three are the same compound. MK-677 comes from the development code MK-0677, and mk777, mk-777, mk 777, mk67 and mk 77 are transposed or truncated typings of it. Searches for mk677 liquid or mk677 pills refer to presentation, not to a different chemical. /
