⚠️ WARNING: Health Risks of Anabolic Steroids
Anabolic steroids significantly impact the body and require professional supervision. Improper use may cause serious health risks including hormonal disruptions, liver stress, heart problems, and mental health changes. Always source steroids from reputable suppliers and use them responsibly if you choose to proceed.
YK 11 Deus Medical
YK 11 by Deus Medical is one of the most advanced and unique compounds in the world of performance enhancement. While frequently categorized as a Selective Androgen Receptor Modulator (SARM), YK 11 is structurally a steroidal SARM derived from Dihydrotestosterone (DHT).1
What makes YK 11 revolutionary is its dual-action mechanism: it acts as a partial agonist of the androgen receptor while simultaneously functioning as a Myostatin Inhibitor.2 By stimulating the expression of Follistatin, YK 11 effectively removes the "genetic ceiling" on muscle growth, allowing for levels of hypertrophy and strength that were previously thought impossible without high-dose anabolic steroids.3

Core Performance & Anabolic Benefits
Myostatin Inhibition: YK 11 triggers the production of Follistatin, a protein that neutralizes Myostatin.4 Since Myostatin is the body's natural "brake" on muscle size, YK 11 allows for rapid, uncapped muscle growth.5
DHT-Derived Hardness: Because it is structurally related to DHT, YK 11 provides an incredible "dry" look, significantly increasing muscle hardness and vascularity without any water retention.
Bone Mineral Density: Research indicates that YK 11 activates Akt-signaling pathways, which can lead to increased bone strength and mineralization, providing a solid foundation for new muscle mass.6
Rapid Strength Gains: Due to its unique gene-selective transactivation, users often report significant jumps in their maximal lifts within the first 14 days of use.
Muscle Fiber Splitting: By promoting myogenic differentiation, YK 11 has the potential to help create new muscle fibers (hyperplasia) rather than just inflating existing ones.
Usage & Dosage (Research-Based)
YK 11 is an extremely potent compound.7 Even at low doses, its impact on protein synthesis is profound.
| Metric | Recommendation |
| Standard Dosage | 5 mg to 10 mg daily |
| Cycle Duration | 4 to 8 Weeks (due to its high potency) |
| Timing | Once daily or split into two doses (Morning/Evening) |
| Administration | Oral tablets |
Warning: YK 11 is a powerful research chemical. It is significantly more suppressive and demanding on the body than standard SARMs like Ostarine.
Side Effects & Hormonal Management
Despite its selective nature, YK 11 carries risks that require a disciplined approach:
Hormonal Suppression: YK 11 will suppress natural testosterone production.8 A comprehensive Post Cycle Therapy (PCT) is mandatory to prevent a hormonal crash.
Liver Strain: As an oral compound with a steroidal structure, it can increase liver enzymes.9 Cycle support (like NAC) is highly recommended.
Joint Sensitivity: Because YK 11 creates a very "dry" environment, some users report joint dryness. Stacking with a collagen-supporting compound can help.
Androgenic Effects: While selective, some users may experience mild acne or hair shedding if they are genetically prone, due to its DHT-based structure.
Frequently Asked Questions (FAQ)
1. Is YK 11 a SARM or a Steroid?
It is both. Technically, it is a synthetic steroidal SARM.10 It has the chemical backbone of a steroid but is designed to target androgen receptors selectively. This hybrid nature is what gives it such unique muscle-building power.
2. Can I stack YK 11 with other SARMs?
Yes, it is often stacked with LGD-4033 for a massive bulking phase or RAD-140 for an ultra-hard, dry look. However, due to the increased suppression, the PCT must be very robust.
3. Does YK 11 cause a "Myostatin Rebound"?
There is no clinical evidence of a rebound effect where myostatin spikes after you stop. However, once you remove the inhibitor, your body returns to its natural genetic limits, making proper PCT and training essential to keep your gains.
4. Why is the dosage lower than other SARMs?
YK 11 works at the level of gene expression (Follistatin production).11 It is incredibly efficient; 5 mg to 10 mg is usually all that is required to trigger a significant biological shift in muscle growth.
