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
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 The CORE SARMs Handbook.

Important
Dietary supplement use only
Start with lower doses if new to stacking. Monitor response carefully. Never go beyond 10 weeks.
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
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
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?
Recommended for intermediate and advanced users who already have experience training with SARMs.
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
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.

Frequently Asked Questions
Contact supportThe bundle includes Ligandrol (LGD4033), Testolone (RAD140), Ostarine (MK2866), and Ibutamoren (MK677) – a complete muscle-building stack.
Users typically gain 15-25 pounds of muscle during an 8-10 week cycle with proper diet and training.
This stack is recommended for intermediate to advanced users who have experience with individual SARMs first.
Follow the individual dosing guidelines for each product. Start with lower doses if stacking for the first time.
This stack is generally well-tolerated when used responsibly. Some users may experience mild effects such as temporary fatigue, increased appetite, or minor water retention. Always follow dosing guidelines and monitor your body’s response.
SARM users usually report subtle gains in the first two weeks, with the outcomes increasing over the course of the cycle.
Yes. A whole bundle of muscle-building SARMs may have a strong impact on your body. Thus, you should follow up with a post-cycle therapy, including a PCT supplement. While it is not mandatory, it’s also recommended to take blood tests to assess the level of hormonal suppression and check whether your body has undergone a full recovery.
The typical post-cycle therapy lasts between 2 and 4 weeks. The exact length of the PCT depends on the impact of the SARMs on your body and the time you need to restore your hormone levels to normal.
During the PCT, you may experience some muscle mass drops. To minimise them and maintain the effects, you should opt for a high-protein diet and a proper post-cycle therapy routine & supplementation. Maintain your training routine even during PCT, as this will also help you build and maintain muscle mass.
