MK 677 (Ibutamoren)

What is MK 677 (Ibutamoren)?

MK 677, or Ibutamoren, is a non-peptide growth hormone secretagogue classified as an oral compound in this 25 mg/tab, 100-tab pack from Dragon Pharma. Developed for muscle-wasting conditions, it's widely used in bodybuilding to increase growth hormone (GH) and IGF-1 levels for muscle growth and recovery. As an oral compound, it has minimal hepatotoxicity, no aromatization, and no significant HPTA suppression, though monitoring is advised.

Mechanism of Action MK 677 (Ibutamoren)

Ibutamoren mimics ghrelin, binding to ghrelin receptors to stimulate the pituitary gland, increasing GH and IGF-1 levels without elevating cortisol. This promotes protein synthesis, nitrogen retention, and fat metabolism, leading to muscle growth and improved recovery. Users notice enhanced muscle fullness, better sleep, and fat loss within weeks.

With a half-life of approximately 24 hours, MK 677 requires daily dosing for consistent effects. It doesn't interact with androgenic or estrogenic pathways, ensuring no hormonal disruptions. What doesn't happen: no significant testosterone suppression or estrogenic effects, but water retention may occur.

Overuse may cause side effects like water retention or increased appetite, manageable with proper dosing and monitoring.

How It Works & Key Benefits

MK 677 excels for bodybuilders in bulking or cutting cycles, requiring a high-protein diet and training to maximize its GH-boosting effects.

• Stimulates GH and IGF-1 for muscle growth.
• Enhances recovery, reducing training downtime.
• Promotes fat loss while preserving lean muscle.
• Improves sleep quality for better recovery.
• Boosts appetite for bulking calorie needs.
• Stacks effectively for tailored performance goals.

Who It's For & Product Specifications

Best for beginner to advanced bodybuilders and athletes seeking muscle growth, recovery, and fat loss; suitable for men and women with careful dosing. Not recommended for those with insulin resistance or without medical clearance.

How to Use

1. Dosage: 10-25 mg/day for men, 5-10 mg/day for women; start at 10 mg to assess tolerance.
2. Frequency: Daily, preferably at night to align with natural GH pulses.
3. Cycle length: 8-12 weeks, with breaks to prevent tolerance.
4. Preparation/Monitoring tips: Take with water; monitor glucose and IGF-1 via labs; maintain high-protein diet (2g/kg body weight); use liver support like milk thistle if needed.
5. Results timeline: Improved sleep and recovery in 1-2 weeks; muscle and fat loss benefits in 4-8 weeks.
6. PCT timing: Typically not required as MK 677 causes minimal HPTA suppression; align with steroid stack's PCT if combined (e.g., 3-4 days post-short ester).

Popular Stacks

Comparisons & Alternatives

MK 677 vs HGH: MK 677 stimulates natural GH release orally; HGH provides direct supplementation with higher cost.

MK 677 vs Ipamorelin: MK 677 offers oral convenience and appetite increase; Ipamorelin is injectable with no appetite effects.

MK 677 vs LGD 4033: MK 677 boosts GH and recovery; LGD 4033 targets muscle growth with mild suppression.

Side Effects & Risk Management

• Systemic: Water retention, increased appetite—manage diet, monitor weight.
• Endocrine: Rare insulin sensitivity changes—monitor glucose levels.
• Cardiometabolic: Minor BP or lipid changes—monitor labs, use omega-3s.
• Hepatic: Minimal strain—routine liver tests advised.
• Dermatologic: None; no androgenic effects.

Review labs with a professional where lawful to ensure authenticity and disciplined dosing for safety.

Post-Cycle Therapy (PCT)

MK 677 typically requires no PCT due to minimal HPTA suppression; align with steroid stack's PCT if combined (e.g., 3-4 days post-short ester). Use tamoxifen or clomiphene for 4 weeks if needed, guided by bloodwork.
