Research summary on YK-11 (also known as Myostatin Inhibitor YK-11).
YK-11 is a Selective Androgen Receptor Modulator (SARM)
YK-11 is a Selective Androgen Receptor Modulator (SARM) — unique for also acting as a myostatin inhibitor, potentially unlocking greater muscle growth.
In research settings, it has been shown to:
✔ Increase muscle cell differentiation and size.
✔ Reduce myostatin activity in muscle tissue.
✔ Support rapid strength development.
🚫 MYOSTATIN INHIBITION:
YK-11’s ability to down regulate myostatin expression may allow for greater muscle hypertrophy than SARMs without this effect.
⚡ ACCELERATED STRENGTH:
Research models indicate faster increases in muscular strength compared to baseline.
📈 CELLULAR GROWTH:
By promoting follistatin expression, YK-11 supports muscle cell development and repair.

Research summary on Testolone (also known as RAD-140).
RAD 140, also known as Testolone, is a non-steroidal selective androgen receptor modulator.
RAD-140 (Testolone) is a Selective Androgen Receptor Modulator (SARM) — studied for its high anabolic-to-androgenic ratio and potential neuroprotective benefits.
In research settings, it has been shown to:
✔ Stimulate significant muscle growth.
✔ Enhance strength and power output.
✔Exhibit neuroprotective effects in research models.
📏 LEAN MUSCLE RETENTION:
RAD-140 has been observed to induce robust gains in lean muscle mass, even at low research dosages.
⚡ PERFORMANCE ENHANCEMENT:
Its anabolic effects contribute to improvements in maximal strength and explosive power.
🧩 BRAIN HEALTH:
Animal studies suggest RAD-140 may offer neuroprotective benefits by reducing cell death in neurons.

Research summary on LGD-4 (also known as Ligandrol or VK-5211).
LGD-4, also known as Ligandrol or VK5211, is a research compound classified as a selective androgen receptor modulator (SARM).
Ligandrol is a Selective Androgen Receptor Modulator (SARM) — known for its potent anabolic activity in muscle and bone tissue.
In research settings, it has been shown to:
✔ Increase lean body mass even at low doses.
✔ Enhance muscle strength and endurance capacity.
✔ Aid recovery from musculoskeletal injury.
💥 MUSCLE HYPERTROPHY:
Clinical studies have shown Ligandrol to significantly increase lean muscle mass in healthy adults within just weeks of administration.
🪨 STRENGTH GAINS:
Participants in research trials have demonstrated measurable improvements in lifting strength and muscular endurance.
🔄 RECOVERY SUPPORT:
By promoting anabolic signaling, Ligandrol can aid in tissue repair following injury or intense training.
