MK-677 (Ibutamoren) 12.5 mg by Peptide Sciences USA

Brand: Peptide Sciences USA

Substance: Ibutamoren

Action of the Drug

MK-677 is a potent growth hormone secretagogue that stimulates endogenous GH and IGF-1 levels, supporting muscle growth, fat metabolism, and tissue repair in research settings.

Use in Sports

Studied for enhancing lean muscle mass, recovery, and anabolic effects. Commonly used in protocols investigating growth hormone pathways and anti-aging research.

Period of Drug Withdrawal

After cessation, elevated GH and IGF-1 levels gradually return to baseline over several days, depending on dosage and individual response in research studies.

Rate of Suppression of Natural Testosterone Production

MK-677 does not suppress natural testosterone production, allowing co-use with other peptides or anabolic compounds in controlled studies.

What Should Be Used During and After Use

During use:

• Follow research-approved dosing protocols
• Monitor GH and IGF-1 response

After use:

• Document changes in lean mass, recovery, and metabolic markers

Combinations with Other Anabolic and Androgenic Drugs

Can be combined with other peptides or anabolic compounds in research to study synergistic effects on muscle growth, recovery, and fat metabolism.

Possible Side Effects and How to Avoid Them

• Mild water retention – adjust protocol as needed
• Temporary increase in appetite – track dietary intake during studies

Why We Recommend It

MK-677 12.5 mg is ideal for research focused on growth hormone release, lean muscle development, and recovery mechanisms.

Comparison with Other Drugs

Compared to injectable GH, MK-677 offers oral administration and sustained GH elevation, making it convenient for controlled research protocols.

Main Properties

• GH Stimulation: Promotes endogenous growth hormone release
• Muscle Support: Enhances lean mass and recovery
• Non-Suppressive: Safe for co-use with other anabolic agents
• Convenient: Oral peptide for research purposes

MK-677 (Ibutamoren) 12.5 mg by Peptide Sciences USA is a premium peptide for growth hormone research, muscle growth, and recovery studies.
