Are you ready to take your physique to the next level? VST Research Labs brings you the Muscle Builder Stack, a powerful combination of two industry-leading compounds: MK-677 (Ibutamoren) and RAD-140 (Testolone). This dynamic duo is designed for those who are serious about muscle growth, recovery, and performance enhancement. Whether you're an athlete, bodybuilder, or fitness enthusiast, the VST Research Labs Muscle Builder Stack offers unparalleled benefits in building lean muscle mass, boosting strength, and optimizing your overall body composition.


What’s in the Stack?

  1. MK-677 (Ibutamoren): Known as a growth hormone secretagogue, MK-677 works by increasing the levels of growth hormone and IGF-1 (Insulin-Like Growth Factor) in the body without affecting cortisol levels. This results in several key benefits, including enhanced muscle growth, improved fat metabolism, faster recovery, and better sleep quality.

  2. RAD-140 (Testolone): RAD-140 is one of the most potent SARMs (Selective Androgen Receptor Modulators) available, specifically designed to mimic the effects of testosterone without the harmful side effects often associated with anabolic steroids. It binds selectively to androgen receptors in muscle and bone tissue, promoting rapid muscle growth, increased endurance, and strength without impacting other organs or causing hormonal imbalances.


The Perfect Synergy for Muscle Growth

The VST Research Labs Muscle Builder Stack combines the unique properties of MK-677 and RAD-140 to create a synergistic effect that accelerates muscle building and recovery beyond what either compound could achieve alone.

  • Increased Lean Muscle Mass: RAD-140’s selective action on muscle tissue promotes anabolic activity, resulting in faster muscle growth and retention of lean mass, even during calorie deficits. When paired with MK-677, which elevates growth hormone levels, you can expect superior gains in muscle size and strength.

  • Enhanced Fat Loss: MK-677 not only supports muscle growth but also enhances fat oxidation by boosting metabolic rate. Combined with RAD-140’s ability to preserve lean mass, the stack helps users achieve a more defined, muscular physique while reducing body fat percentage.

  • Boosted Strength and Performance: RAD-140’s anabolic effects lead to notable increases in strength and endurance, making your workouts more productive. This enables you to push through plateaus and lift heavier weights, driving further muscle growth. The added benefit of MK-677’s support in recovery means less downtime between intense training sessions.

  • Accelerated Recovery: MK-677 is well-known for improving recovery times by stimulating the production of growth hormone and IGF-1, both of which play a crucial role in tissue repair. This means faster healing of muscles, ligaments, and tendons, allowing you to get back in the gym sooner and train at your best.

  • Improved Sleep and Overall Well-Being: One of the often-overlooked benefits of MK-677 is its positive impact on sleep. Enhanced sleep quality leads to better recovery, more energy, and increased muscle repair during rest. A good night’s sleep, combined with the muscle-building effects of RAD-140, sets the stage for maximum performance in the gym.


Who Should Use the Muscle Builder Stack?

The VST Research Labs Muscle Builder Stack is designed for those who are committed to maximizing their muscle-building potential. If you are:

  • Looking to gain lean muscle mass rapidly
  • Wanting to break through strength plateaus
  • Striving for faster recovery and reduced muscle soreness
  • Seeking to improve body composition by reducing fat while preserving muscle
  • Focused on optimizing your performance and recovery through enhanced hormonal pathways

This stack is for you.


Dosage and Cycle Recommendations

For best results, it’s recommended to follow a 6-8 week cycle:

  • MK-677: 25 mg per day
  • RAD-140: 10-20 mg per day

Both compounds have long half-lives, so they can be taken once per day. MK-677 can be taken in the morning or before bed to take advantage of its sleep-enhancing properties. RAD-140 is best taken in the morning to support daytime strength and performance.

Post Cycle Therapy (PCT) is recommended after completing the stack, as RAD-140 can slightly suppress natural testosterone levels. While MK-677 is non-suppressive, a mild PCT ensures your body’s hormonal balance is restored, preserving your hard-earned gains.


Take Your Gains to the Next Level

The VST Research Labs Muscle Builder Stack combines two of the most effective compounds in the fitness world today to help you achieve the body you’ve always wanted. Experience accelerated muscle growth, enhanced recovery, improved sleep, and a leaner, stronger physique. This is your ultimate solution for maximizing hypertrophy and performance.

Unlock your full potential with VST Research Labs Muscle Builder Stack: MK-677 and RAD-140.
