HalaWARLORN MK-677 + RAD-140 is a potent performance-enhancing stack designed for muscle growth, fat loss, and improved recovery. MK-677 (Ibutamoren) stimulates natural growth hormone release, aiding in muscle gain and fat reduction, while RAD-140 (Testolone) is a selective androgen receptor modulator (SARM) known for boosting lean muscle mass and strength without the side effects of steroids.

What It Is

• A combined stack of Ibutamoren (MK-677) and RAD-140 (Testolone).
• MK-677 is a growth hormone secretagogue that stimulates GH and IGF-1 release.
• RAD-140 is a potent SARM (Selective Androgen Receptor Modulator) that targets muscle tissue for anabolic effects.

Key Features & Potential Benefits

• Muscle Growth & Strength: RAD-140 promotes muscle protein synthesis and strength gains; MK-677 supports growth hormone, which can enhance tissue growth and repair.
• Enhanced Recovery: MK-677’s GH/IGF-1 boost helps with recovery from workouts and may reduce muscle soreness.
• Better Sleep: MK-677 often improves sleep quality, which further supports recovery.
• Increased Appetite: MK-677 is known to drive hunger, which can be useful for bulking cycles.
• Lean Body Composition: While RAD-140 helps build muscle, MK-677 can aid in maintaining lean mass due to its growth-hormone effects.
• Bone & Joint Support: MK-677 may help with bone density and joint recovery because of its GH-stimulating effect.

Potential Risks & Side Effects

• Hormonal Suppression: RAD-140 may suppress natural testosterone production, which could require Post-Cycle Therapy (PCT).
• Water Retention / Bloating: MK-677 can cause fluid retention, especially when started or at higher doses.
• Increased Blood Sugar: MK-677 may affect glucose metabolism; monitoring is advised for insulin sensitivity.
• Liver Stress: There is potential risk of liver strain when using strong SARMs; blood work is recommended.
• Mood & Appetite Changes: Users may experience mood swings, increased appetite, and possibly lethargy.
• Long-Term Safety Unknown: Long-term combined use of these compounds is not well studied in humans.

Usage / How to Use (Typical Protocol)

• RAD-140 Dose: Commonly in the range of ~10 mg per day in research use.
• MK-677 Dose: Often used around 10–25 mg per day, depending on goals (recovery, bulking) and tolerance.
• Cycle Length: Many people run cycles of 8–12 weeks for RAD-140; MK-677 may be used similarly or for longer depending on the protocol.
• Timing:
  • RAD-140: Often taken in the morning to support consistent blood levels.
  • MK-677: Frequently taken in the evening or before bed to support sleep and recovery.
• PCT (Post-Cycle Therapy): Because RAD-140 can suppress testosterone, many users consider using a PCT protocol afterward.
• Support & Monitoring: It's recommended to monitor blood markers (hormones, liver enzymes, glucose) before, during, and after the cycle.

My Assessment

Strengths:

• Very powerful bulking / recovery stack: RAD-140 gives strong anabolic effects, while MK-677 adds hormonal support and recovery enhancement.
• Good for users who want to increase mass and strength while improving recovery and sleep.
• The appetite boost from MK-677 can help with eating more to support muscle growth.

Drawbacks / Risks:

• High risk of hormonal imbalance if PCT is not planned carefully.
• Water retention and blood sugar changes may be problematic for some users.
• Because both compounds are potent and not fully studied for combined long-term use, the risk-benefit ratio is uncertain for many people.
• Requires disciplined monitoring (bloods, diet, sleep) to minimize potential harm.
