Ostarine (MK-2866)
Ostarine (MK-2866) is a selective androgen receptor modulator (SARM) frequently examined in research related to anabolic signaling, nutrient partitioning, and lean tissue preservation. It is a non-steroidal compound designed to selectively interact with androgen receptors in muscle and bone, making it valuable in laboratory investigations of targeted anabolic pathways.
Research Overview
Within controlled research settings, Ostarine is often evaluated for its ability to influence protein synthesis and nitrogen retention without the same off-target receptor activity seen in traditional anabolic agents. It is referenced in both catabolic resistance and muscle maintenance studies, as well as nutrient utilization experiments.
Key Research Points
- Supports lean tissue retention under caloric restriction
- Assessed for strength and endurance response markers
- Observed effects on joint integrity and bone tissue
- Low-level androgenic binding with favorable anabolic ratio
Observed Laboratory Outcomes
- Measured increases in lean body mass indicators
- Reduced muscle catabolism under deficit conditions
- Improved tissue recovery and fatigue resistance markers
- Down-regulation of serum testosterone at higher equivalence levels

Reference Sampling Table (Tablet-Based Model)
| Research Context | Reference Equivalent | Observation Frequency | Sampling Duration |
|---|---|---|---|
| Cutting / Caloric Restriction Model | 1 tablet (12.5 mg) | Every 24 hours | 4 weeks |
| Recomposition / Nutrient Partitioning Study | 1–2 tablets (12.5–25 mg) | Every 24 hours | 4–6 weeks |
| Bulking / Growth Phase Evaluation | 2–3 tablets (25–37.5 mg) | Every 24 hours | 6 weeks |
These equivalence levels are provided for laboratory reference only and are not medical or therapeutic dosing instructions.
Stack Compatibility (Research Context)
- Metabolic Studies: Ostarine is often evaluated alongside Cardarine (GW-501516) to study endurance and lipid oxidation.
- Recovery and GH Interaction: Combined reference with Nutrobal (MK-677) for comparative GH/IGF modulation analysis.
- Maintenance Models: Used at reduced equivalence (½–1 tablet) in long-term tissue health observations.
