Description
Our Liquid MK-777 comes ready to measure: 20mg/mL of MK-777 (acetamoren) in PEG-400, 30mL per bottle. It’s an acetylated ibutamoren derivative. Sports Technology Labs supplies it for in-vitro research only.
What is MK-777 (acetamoren)?
MK-777, also called acetamoren, is N-acetyl ibutamoren: the non-peptide ghrelin mimic MK-677 with an acetyl group added.
Almost no peer-reviewed research exists on the acetylated form itself. What’s known comes from its parent compound, so treat it as a newer research chemical.
What MK-777 does in cells
Like MK-677, it’s designed to act on the ghrelin receptor, GHS-R1a, which triggers growth hormone release from the pituitary.
The acetyl group changes the molecule’s polarity, and the idea is that it changes how the compound is absorbed and broken down. That hasn’t been confirmed in published studies.

What the literature says about MK-777
The research behind it belongs to MK-677 (ibutamoren). Merck’s studies in the 1990s showed that the parent compound raises GH and IGF-1 in an oral, once-daily form.
For a study using MK-777, running MK-677 as a reference arm is the obvious way to see whether the acetyl group changes anything.

MK-777 compared with similar compounds
MK-777 is an acetylated version of MK-677 with very little published data. Here’s how the nearest options in our range differ:
- Cardarine is a PPAR-delta agonist studied for endurance and fat burning in mice
- SR-9009 is a REV-ERB agonist that acts on the body clock and muscle metabolism in mice
- MK-677 is an oral ghrelin mimic that raises GH and IGF-1 and isn’t a SARM
- RU-58841 is a topical antiandrogen that blocks the androgen receptor instead of activating it
- Ostarine is the most studied SARM, with human trial data on muscle wasting
These are often sold next to SARMs but work through other targets: PPAR-delta, REV-ERB, the ghrelin receptor or androgen blockade. Compare them in our liquid SARMs.
Measuring Liquid MK-777 accurately
Each 30mL glass bottle holds 20mg of MK-777 per mL in USP-grade PEG-400, 600mg in total. A graduated 1mL glass pipette comes with every bottle.
Measuring is simple arithmetic: 0.5mL holds 10mg and 0.1mL holds 2mg. Read the pipette at eye level, since PEG-400 is thick and clings to the glass.
Keeping Liquid MK-777 stable
Keep the bottle tightly closed in a cool, dry place out of direct sunlight. The amber or UV-resistant glass helps, but a cupboard is better than a windowsill.
Label the date you opened the bottle so your records match your results.
How Sports Technology Labs tests Liquid MK-777
Every batch is sent to MZ Biolabs in Tucson, Arizona, before it goes on sale. They run HPLC for purity and mass spectrometry to confirm identity. The latest certificates for this product read 99.12%.
The COA image is in the product gallery at the top of this page, so you can read the batch result before you order.
HPLC and mass spec answer different questions. HPLC tells you what share of the sample is the main compound. Mass spec tells you the compound is the right molecule. A COA with only one of them leaves a gap.
If anything arrives wrong, the 60-day money-back guarantee covers it.
