MK-2866 (Ostarine) 10mg – Driada Medical EU

MK-2866, widely known as Ostarine (or Enobosarm), is one of the most popular and versatile Selective Androgen Receptor Modulators (SARMs) on the market.¹ Manufactured by Driada Medical EU, this compound is celebrated in the fitness community for its exceptional safety profile and its ability to preserve lean muscle mass during aggressive cutting cycles.

Product Specifications

Mechanism of Action: Why Choose Ostarine?

Ostarine works by selectively targeting androgen receptors (AR) specifically in muscle and bone tissue.² Unlike traditional anabolic steroids, it minimizes activation in other organs (like the prostate), resulting in fewer androgenic side effects.³

Key Benefits

• Muscle Preservation (Anti-Catabolic): Ostarine is the "king of cutting." It prevents muscle breakdown (catabolism) even when you are in a caloric deficit, ensuring that the weight you lose is fat, not muscle.

• Joint Healing & Bone Density: Unique among SARMs, MK-2866 is reported to improve joint health and tendon repair, making it ideal for athletes recovering from injuries or lifting heavy loads.

• Lean Muscle Gains: While milder than other SARMs, it promotes steady, dry lean muscle gains without water retention.

• Oral Bioavailability: No injections required. It is orally active and easy to dose.

Usage, Dosage, and Cycles

Ostarine is versatile and can be used for cutting, recomp (losing fat and building muscle simultaneously), or lean bulking.

Recommended Dosage

• Typical Dosage: 10 mg to 30 mg per day.

• Beginners: Often start at 10–20 mg/day.

• Advanced Users: May titrate up to 30 mg/day.

Cycle Protocols

• Frequency: Due to its 24-hour half-life, Ostarine should be taken once daily.

• Cycle Length: A standard cycle lasts 8 to 12 weeks.

• Stacking: It is often stacked with other compounds (like Cardarine) for enhanced fat loss, though it is powerful enough to be run solo.

Side Effects and Post-Cycle Therapy (PCT)

Ostarine is considered one of the mildest SARMs, but it is not free of side effects. Responsible use involves understanding the risks.

• Testosterone Suppression: MK-2866 causes mild suppression of your body's natural testosterone production. It does not usually shut down production completely, but suppression increases with higher doses and longer cycles.

• PCT Requirement: A Post-Cycle Therapy (PCT) is generally recommended.⁴ A mild protocol using a SERM (like Nolvadex or Clomid) for 3–4 weeks post-cycle helps restore natural hormone levels.⁵

• Lipid Profile: Temporary lowering of HDL (good cholesterol) may occur.

• Liver Health: While not as toxic as oral steroids, monitoring liver enzymes is good practice.

Frequently Asked Questions (FAQ)

1. What is the main advantage of Ostarine over steroids?

The main advantage is selectivity. Because Ostarine is a SARM, it targets muscle and bone receptors specifically.⁶ This allows for anabolic benefits (growth and repair) without the severe androgenic side effects associated with steroids, such as prostate enlargement or severe hair loss.

2. Do I really need a PCT for Ostarine?

Yes, it is recommended. While Ostarine is mild, it does suppress natural testosterone levels, especially during an 8–12 week cycle. A mini-PCT ensures you keep your gains and recover your natural hormonal balance quickly.

3. Can Ostarine heal joints?

Anecdotal evidence and research suggest Ostarine increases collagen synthesis and improves bone density.⁷ Many bodybuilders use it specifically to treat nagging joint injuries or tendonitis while training.

4. Is Ostarine good for bulking?

It can be used for lean bulking, but it is best known for cutting and recomposition. If your primary goal is massive bulk, other compounds (like LGD-4033) are more potent, whereas Ostarine excels at keeping you lean and holding onto muscle while dieting.
