$99.00
Manufacturer: XT Labs USA
Product Name: YK11 5
Active Substance: Myostatin (via YK11)
Pack Size: 60 pills × 5 mg
Form: Oral Tablets
Each tablet contains 5 mg of YK11, an orally active compound classified as a Selective Androgen Receptor Modulator (SARM), alongside other inactive stabilizing ingredients.
YK11 5 is a myostatin-inhibiting compound developed to explore muscle-building and performance-enhancing mechanisms. Structurally, it belongs to the Selective Androgen Receptor Modulator (SARM) family and acts as a partial agonist of androgen receptors.
Unlike traditional anabolic substances, YK11 interacts selectively with androgen receptors, aiming to promote muscle hypertrophy and bone density improvements while minimizing broader androgenic effects.
YK11 operates by binding to androgen receptors (ARs) within muscle and bone tissue. Once activated, these receptors trigger anabolic processes, including muscle protein synthesis and cellular regeneration.
A key distinction of YK11 is its ability to stimulate follistatin production. Follistatin is a regulatory protein that inhibits myostatin — a molecule responsible for limiting muscle growth.
By blocking myostatin activity, YK11 potentially allows for greater muscle development and enhanced strength output.
| Mechanism | Effect |
|---|---|
| Partial Androgen Receptor Activation | Promotes anabolic activity in muscle and bone |
| Follistatin Stimulation | Suppresses myostatin, allowing muscle expansion |
| Myostatin Inhibition | Increases potential for lean mass and strength gains |
While scientific research on YK11 remains limited, early findings and anecdotal reports suggest the following outcomes:
Enhanced muscle growth and strength
Improved muscle definition and density
Increased bone strength and structural support
No water retention, allowing for leaner gains
Accelerated recovery between training sessions
These effects vary among individuals and depend heavily on training, diet, and overall health. Always consult a qualified medical professional before use.
Suggested Dosage: 5 mg daily
Method: Oral (tablet form)
Timing: Once daily, ideally at the same time each day
Cycle Length: Generally discussed as 4–8 weeks in research contexts
Since YK11 is methylated, it is metabolized through the liver; therefore, cycle support supplements (such as TUDCA or NAC) are often recommended to support hepatic function.
Do not exceed the suggested dosage. Misuse or prolonged use may increase health risks.
Although YK11 is often discussed as a “selective” compound, it can still influence hormonal and metabolic processes. Potential side effects may include:
Natural testosterone suppression
Liver strain or elevated enzyme levels
Acne or oily skin
Mood changes or anxiety
Insomnia or restlessness
Nausea or stomach upset
Reduced libido
Rare or excessive use has been associated with more severe consequences such as hormonal imbalance or cellular toxicity.
Users are strongly advised to undergo medical supervision and regular blood tests when using compounds that affect androgen receptors.
YK11 may interact with other SARMs or androgenic compounds, potentially amplifying both positive and negative effects.
Combining multiple selective receptor modulators can increase stress on the liver, lipid profile, and hormonal system.
Avoid concurrent use with other hepatotoxic or hormonal agents unless guided by a licensed professional.
Due to possible suppression of natural testosterone levels, users typically follow a Post-Cycle Therapy (PCT) protocol after discontinuing YK11.
A well-structured PCT can assist in:
Rebalancing endogenous hormone production
Supporting liver recovery
Maintaining gains achieved during the cycle
Common PCT agents (used under medical supervision) may include Clomiphene Citrate or Tamoxifen Citrate, depending on cycle duration and individual response.
Conduct baseline blood tests before starting use
Monitor liver enzymes and lipid profile regularly
Maintain a balanced diet and stay hydrated
Avoid alcohol or other liver-stressing substances
Discontinue immediately if experiencing severe side effects
YK11 should only be used by individuals with advanced experience in managing SARMs or similar compounds.
Not suitable for women, minors, or individuals with liver, kidney, or heart conditions.
Store at room temperature (15–25°C)
Keep away from direct sunlight and humidity
Close tightly after each use
Keep out of reach of children and pets
YK11 5 (XT Labs USA) delivers 5 mg of Myostatin-modulating YK11 per tablet, designed for oral use. Acting as a partial androgen receptor activator, it may enhance follistatin levels and inhibit myostatin, resulting in greater potential for muscle growth, strength, and recovery.
However, due to its methylated structure and impact on hormone regulation, responsible use, liver support, and post-cycle recovery are essential for minimizing risks.
Please note that XT Labs USA is a UGL (Underground Lab) brand. These are not pharmagrade products, but each batch is tested for purity and potency.
If used alongside SARMs or other anabolic compounds, ensure to follow proper Post Cycle Therapy (PCT) when applicable.
