Project X X-Ray

Project X X-Ray is a high-strength YK-11 formula by Project X, designed for experienced users looking to push beyond conventional muscle-building limits. YK-11 acts as both a SARM and a myostatin inhibitor, making it one of the most potent compounds for lean muscle growth. Each bottle contains 60 capsules.

YK-11 is a unique compound that acts as both a selective androgen receptor modulator (SARM) and a myostatin inhibitor. By inhibiting myostatin, YK-11 can theoretically remove the natural ceiling on muscle growth, allowing for enhanced lean muscle mass gains beyond what is possible with standard supplementation.

Project X X-Ray supports myostatin inhibition for enhanced muscle growth potential, significant lean muscle mass gains, increased strength and power, improved bone density support, and is suitable for both bulking and recomposition cycles.

Take the recommended daily dose as directed. YK-11 cycles typically run 4–8 weeks, followed by a structured break and post-cycle therapy (PCT). Given its potency as a myostatin inhibitor, careful monitoring is advised. Always consult a healthcare professional before use.

Project X X-Ray is intended for experienced adult users aged 21 and over who are familiar with advanced structured supplementation protocols. It is not suitable for beginners, women, or individuals with pre-existing health conditions.

No. Project X X-Ray is one of the most potent SARM-class compounds available, intended exclusively for experienced advanced users. Beginners should not use this product without prior experience in structured supplementation and cycle management.

Project X X-Ray is primarily associated with lean mass building and recomposition due to its myostatin-inhibiting properties. It is particularly popular for advanced bulking cycles where maximal muscle growth potential is the goal.

The active ingredient is YK-11, a compound that functions as both a SARM and myostatin inhibitor. Additional excipients support capsule stability and consistent delivery. Each bottle contains 60 capsules.

YK-11 is considered one of the more potent SARM-class compounds and may cause testosterone suppression. Post-cycle therapy (PCT) is essential after completing a cycle. Liver support during the cycle is recommended. Regular blood work and consultation with a healthcare professional before use is strongly advised.
