This muscle-building bundle works by targeting multiple pathways for muscle growth simultaneously. Ligandrol and Testolone provide powerful anabolic effects, while Ostarine ensures muscle preservation and recovery. Ibutamoren supports the entire process through enhanced growth hormone release.

The combination creates a synergistic effect where each compound enhances the others’ benefits, resulting in faster and more substantial muscle gains than any single compound alone. The bundle addresses all aspects of muscle building: protein synthesis, recovery, strength, and hormonal support.

Users typically experience rapid strength gains, improved recovery, better sleep quality, and substantial muscle growth throughout the cycle.

Key Actions

1 Activates multiple anabolic pathways
2 Enhances protein synthesis and recovery
3 Supports natural growth hormone release

This bundle combines four compounds with different mechanisms, anabolic, growth hormone, and muscle-preserving, so each one covers a gap the others leave open. See the full cycle breakdown in Complete SARMs Compound Guide: Dosages, Cycles & Recovery.

Haim
Muscle Building Bundle
Tried the muscle building stack, took each compound at 10mg. MK-677 gave me the appetite boost I needed to gain size, muscles started feeling fuler on week 2. Also the most important part that helped me was the rekovery time between sets. Overall a really balanced stack that works good together. The only thing I would run LGD-4033 5mg instead of 10mg.

Start with lower doses if new to stacking. Monitor response carefully. Never go beyond 10 weeks.

Training Training

Focus on heavy compound lifts: squats, deadlifts, bench press, rows, and overhead press. Add weight or reps in small increments every 1–2 weeks. Train 4–5 days a week on an upper/lower or push/pull/legs split. Keep cardio light, just 2 low-intensity sessions per week.

Diet Diet

Eat at a surplus of 300–400 calories above maintenance. Protein: 2.0–2.4g per kg of body weight daily. Stick to whole foods and limit saturated fats to protect cholesterol. Drink 3–4 litres of water each day.

Goal Goal

This bundle is built to support steady, balanced lean muscle growth and strength gains. It also helps protect joints and keep water retention down.

Who Can Use This Bundle? Who Can Use This Bundle?

Recommended for intermediate and advanced users who already have experience training with SARMs.

How to Run? How to Run?

Start all four compounds on Day 1 at the same doses each day. Stick to an 8–10 week cycle, never longer. Follow up 3 to 5 days after the cycle with PCT, mandatory given the strength of this bundle.

Universal Rules for SARMs Stacking Universal Rules for SARMs Stacking

Get your baseline bloodwork done before starting, check again 2 weeks into the cycle, and do a final test 2 weeks after PCT finishes. Use liver support, cholesterol aids, and electrolytes for the full duration. After finishing any cycle or stack, take a complete break of at least 12 weeks before starting another.

Post-cycle support

PCT (Post Cycle Therapy)

Recommended after every cycle

€237.50 €250.00 Save 5%

This bundle's combined compounds cause strong suppression, so PCT is mandatory after every cycle. Start your PCT protocol 3 to 5 days after your final dose and run it for a full 4 weeks to restore hormone levels before starting again.
