Description
Ostarine (MK-2866) – Science Bio, 900 mg
A smart approach to protect what’s hardest to build: your lean muscle. Ostarine is a selective SARM valued for its technical profile and its usefulness in body recomposition strategies when you want definition without neglecting lean tissue.
The essentials at a glance
- Muscle preservation in a deficit: when you adjust calories, it helps maintain the muscle that supports your performance and aesthetics.
- Sharper composition: facilitates cutting phases prioritizing a firm, proportionate look—without overblown promises.
- Recovery and continuity: supports that feeling of “keep progressing” between demanding sessions, with fewer ups and downs in your routine.
Who is it for?
For those seeking body recomposition with technical criteria: recreational athletes, strength trainees, or users who want to cut without sacrificing months of work in the gym. Also for profiles that value clear protocols, tracking, and alignment across training, nutrition, and sleep.
How does it work?
As a selective androgen receptor modulator, Ostarine acts on pathways related to lean mass retention, setting itself apart from traditional compounds with a more targeted approach. It is not a steroid and its results are steady and sustained; the advantage lies in stability when the calorie deficit and training load become challenging.
Usage protocol (sublingual)
- Route of administration: sublingual. Hold under the tongue for 60–90 seconds before swallowing.
- Timing: once daily, at the same time. Ideally with the first meal.
- Standard cycle: 4–6 weeks, followed by 2–4 weeks off.
- Indicative dosing*:

- Intermediate: 20 mg/day (≈ 0.7 ml).
- Advanced: 25 mg/day (≈ 0.8–1.0 ml).
- Useful synergies: structured nutrition and progressive strength training, sleep hygiene, and where appropriate, peptide synergy to enhance recovery and definition.
