⚠️ 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.
OSTARINE XT Labs - MK-2866 (Selective Androgen Receptor Modulator)
Product Name: OSTARINE
Manufacturer: XT Labs
Active Substance: Ostarine (MK-2866)
Concentration: 10 mg per tablet
Presentation: 60 Tablets
What is OSTARINE and What Does It Do?
OSTARINE, also known as MK-2866, is a Selective Androgen Receptor Modulator (SARM). It is a non-steroidal compound designed to selectively target and activate androgen receptors in specific tissues, primarily muscle and bone, with the goal of producing anabolic (muscle-building) effects while minimizing androgenic side effects on other organs like the prostate and skin.
Its primary mechanism of action is:
Selective Binding: It has a strong affinity for binding to androgen receptors in anabolic tissues.
Anabolic Stimulation: Once bound, it stimulates protein synthesis, leading to muscle growth and increased strength.
It was originally researched for the treatment of conditions like muscle wasting (cachexia) and osteoporosis.
Purpose in Bodybuilding and Performance Enhancement
Ostarine is one of the most popular and well-researched SARMs, known for its mild yet effective nature. It is used for specific goals:
Lean Muscle Gains: It is effective for promoting moderate, lean muscle gains. It's a popular choice for those seeking a "dry" look without significant water retention.
Muscle Preservation During Cutting: This is one of its primary strengths. Ostarine is highly effective at preserving lean muscle tissue while in a significant calorie deficit, making it a valuable tool during cutting and dieting phases.
Recomposition (Simultaneous Fat Loss & Muscle Gain): It can help users lose body fat while simultaneously gaining a small amount of muscle, especially beginners or those returning to training.
Strength Increases: Users typically experience noticeable increases in strength and endurance.
Injury Rehabilitation: Its selective action on muscle and bone has led to its use for aiding recovery from injuries, though this is an off-label application.
Dosage and Administration
OSTARINE is an oral SARM with a half-life of approximately 24 hours, allowing for once-daily dosing.
Men:
Common Dosage Range: 15 mg to 30 mg per day.
For Muscle Preservation/Cutting: 15 mg - 20 mg per day.
For Lean Mass/Recomposition: 20 mg - 30 mg per day.
Cycle length is typically 8 to 12 weeks.
Women:
Due to its mild nature, it is a popular SARM for female users.
Common Dosage Range: 5 mg to 10 mg per day.
Cycle length is typically 6 to 8 weeks.
Post-Cycle Therapy (PCT) Note: While Ostarine is considered one of the milder SARMs, it is still suppressive of natural testosterone production, especially at doses above 20 mg per day and in cycles longer than 8 weeks. A mini-PCT with a SERM like Nolvadex (10-20 mg/day for 2-4 weeks) is often recommended after a cycle to help restore natural hormone function.
Benefits and Effects
Promotes lean, quality muscle gains.
Effectively preserves muscle mass during a calorie deficit.
Increases strength and endurance.
Enhances muscle hardness and vascularity.
Does not cause estrogen-related side effects like gynecomastia or water retention (as it does not aromatize).
Potential Side Effects and Warnings
While generally considered to have a favorable side effect profile compared to anabolic steroids, Ostarine is not without risks.
Testosterone Suppression: This is the most significant side effect. It will suppress the hypothalamic-pituitary-testicular axis (HPTA), leading to lowered natural testosterone levels, which can cause low libido, fatigue, and mood swings.
Negative Lipid Profile: It can cause unfavorable changes in cholesterol, notably by suppressing HDL (the "good" cholesterol).
Mild Androgenic Side Effects: At high doses, some users report mild androgenic side effects like acne.
Headaches and Lethargy: Some users report these, especially as suppression sets in.
Liver Strain: While considered less hepatotoxic than most oral steroids, some users report elevated liver enzymes.
