What is MK-677 (Ibutamoren) 12.5mg (60 Capsules)

MK-677 (Ibutamoren) 12.5mg (60 Capsules) is a research compound classified as a growth hormone secretagogue. It functions as an orally active, non-peptide agonist of the ghrelin receptor (GHSR-1a). In laboratory research, MK-677 (Ibutamoren) 12.5mg (60 Capsules) has been studied for its ability to mimic the action of ghrelin, thereby stimulating the release of growth hormone (GH) and insulin-like growth factor 1 (IGF-1).

Unlike peptide-based growth hormone-releasing hormones (GHRH) that require injection, this compound offers oral bioavailability, making it uniquely valuable for certain long-term research models. Each capsule contains precisely 12.5mg of lyophilized powder, ensuring accurate dosing for controlled laboratory studies.

For research purposes only. Not for human consumption or clinical use.

What is MK-677 (Ibutamoren) 12.5mg (60 Capsules) Used For (Research Context Only)

In preclinical research settings, MK-677 (Ibutamoren) 12.5mg (60 Capsules) is used to investigate:

• Growth hormone pathways: Studying pulsatile GH secretion and IGF-1 modulation.

• Metabolic research: Examining energy balance, nutrient partitioning, and protein synthesis.

• Muscle wasting models: Understanding mechanisms of muscle preservation under catabolic conditions.

• Sleep and recovery physiology: Due to ghrelin’s role in sleep architecture.

• Aging research: Evaluating the effects of GH/IGF-1 axis restoration in aged animal models.

Researchers do not use MK-677 (Ibutamoren) 12.5mg (60 Capsules) for human treatment, diagnosis, or therapy. All studies must comply with institutional animal care and use committee (IACUC) or equivalent ethical guidelines.

Product Specifications Table

How It Works

MK-677 (Ibutamoren) 12.5mg (60 Capsules) acts as a selective agonist at the ghrelin receptor (GHSR-1a), which is expressed in the pituitary gland and hypothalamus. Upon binding, it stimulates the release of growth hormone-releasing hormone (GHRH) while simultaneously inhibiting somatostatin release. The net effect is a significant, dose-dependent increase in pulsatile GH secretion.

Unlike GHRH analogs, MK-677 (Ibutamoren) 12.5mg (60 Capsules) does not require injection or cold chain maintenance before reconstitution. Its oral bioavailability (~60-70% in preclinical models) allows researchers to administer the compound via oral gavage without the stress of repeated injections, reducing confounding variables related to handling.

The compound’s half-life in research models ranges from 4-6 hours, supporting once-daily administration protocols. GH elevation persists for 8-12 hours post-dose, with corresponding IGF-1 increases sustained for up to 24 hours.

📦 Storage Instructions

Proper storage is critical to maintaining the integrity of MK-677 (Ibutamoren) 12.5mg (60 Capsules). Follow these guidelines:

• Store at -20°C (-4°F) for long-term stability (≥12 months). Use a non-frost-free freezer to avoid temperature cycling.

• Refrigerate after reconstitution (2–8°C / 36–46°F) – Only if reconstituting from lyophilized powder (though our capsules are ready to use).

• Avoid repeated freeze-thaw cycles – Each cycle degrades peptide bonds.

• Protect from light – Store in original amber vial or opaque container.

• Maintain sterile conditions – If opening capsules for reconstitution, use a laminar flow hood.

• Keep desiccant inside container – Moisture accelerates hydrolysis.

• Do not store in bathroom or near heat sources – Humidity and temperature fluctuations cause degradation.

Failure to follow these storage protocols may result in reduced purity and unreliable research data.

🧪 How It Is Used (RESEARCH CONTEXT ONLY)

MK-677 (Ibutamoren) 12.5mg (60 Capsules) is designed for controlled laboratory environments. Typical research applications include:

1. Reconstitution (if using bulk powder) – Dissolve in DMSO or PEG-400 for in vitro studies. For in vivo oral administration, capsules are used directly.

2. Dosing protocols – Common research models (rodents) use 1-10 mg/kg/day. Our 12.5mg capsules are intended for larger animal models or as stock for dilution.

3. Controlled lab environments – Administer under veterinary or IACUC-approved protocols.

4. Precise measurement – Each capsule provides accurate 12.5mg dosing; open and weigh if fractional dosing required.

5. Data collection – Monitor GH and IGF-1 levels via ELISA or LC-MS/MS.

STRICTLY for research purposes only. Not for diagnostic, therapeutic, or human use.

🔗 Peptide Stacking / Combinations

Researchers often combine MK-677 (Ibutamoren) 12.5mg (60 Capsules) with other peptides to study synergistic effects on the GH/IGF-1 axis and tissue repair.

MK-677 + Ipamorelin

• Why combine: Ipamorelin is a selective GHSR agonist with minimal effect on cortisol or prolactin. Stacking allows researchers to study additive GH release without off-target stress hormone elevation.

• Synergistic research interest: Enhanced pulsatility and prolonged IGF-1 elevation.

• Cross-sell opportunity: Buy Ipamorelin USA

MK-677 + CJC-1295 (DAC or no DAC)

• Why combine: CJC-1295 is a GHRH analog that extends GH release. Combining with MK-677 targets both GHRH and ghrelin pathways, maximizing GH output.

• Synergistic research interest: Studying complete GH axis activation versus monotherapy.

• Cross-sell opportunity: Buy CJC-1295 USA

MK-677 + BPC-157

• Why combine: BPC-157 is studied for tissue repair, angiogenesis, and gut health. MK-677’s anabolic effects may complement BPC-157’s healing properties.

• Synergistic research interest: Musculoskeletal regeneration models.

• Cross-sell opportunity: Buy BPC-157 USA

MK-677 + GHRP-2 or GHRP-6

• Why combine: Both are ghrelin mimetics. Researchers compare potency, duration, and receptor desensitization.

• Cross-sell opportunity: Buy GHRP-2 USA

All combinations must be used exclusively in research settings.
