  • Highly Anabolic even at moderate doses
  • Excellent for lean mass gains and fatloss
  • Use with GW501516 for fatloss
  • Truly shines when used for body recomposition
  • Helps increase endurance (aerobic or anaerobic)

  • Great sense of well-being while on
  • Large increases in strength

Ostarine binds to the androgen receptors just like anabolic steroids do, but it does this selectively, which means that it has considerably less side effects.


Ostarine works like anabolic steroids do, but with way fewer side effects, and almost no suppression. In fact, blood work has shown that Ostarine will suppress the HPTA (hypothalamic pituitary testicular axis) by only 10-20% vs. 95% seen with anabolic steroids. Hence, you can use Ostarine as an additional or solo compound not only during your cycle, but also for post cycle therapy (PCT), and even the bridging phase. This makes Ostarine a very versatile compound for the athlete.

Women will find Ostarine to be a much safer alternative to anabolic steroids because it won’t cause facial hair, enlarged clitoris, or other masculine traits.

Furthermore, Ostarine is also popular among powerlifters and bodybuilders due to its ability to strengthen bones and joints.

MK-2866 is highly effective at gaining and maintaining extremely lean body mass. A major benefit is its healing potential when used for injury rehabilitation because it can aid in healing an injury at a rapid rate.


1. Endurance: You can stack MK2866 with GW501516 for increased endurance before your workout or run.
2. Fat Loss: Stack with S4 ‘SHRED’ for ripped, vascular gains.

3.Recomp:  If you want to recomp (build muscle mass while losing fat at the same time), Ostarine stacks beautifully both S4 and GW501516

4.Lean gains: If you wish to make dry, lean gains, stack with RAD140.


25mg daily for 12 weeks.

    This stuff is great. Been playing footy for over 15 years so my body is riddled with injuries. Stacked this with Cardarine for the stamina and MK677 for the injuries.

  2. sandeep

    Used this post cycle to keep my gains before blasting again. Helped me keep most of it. Stacked with Cardarine to lower corstiol. Works well as a PCT bridge stack.

    Just wanted to say a big thank you to the guys at ozsarms for taking the time to answer my questions and recommend sarms for a female in order to get the results i was looking for.

    They went above and beyond in recommending dosages and even sent me sarms dosed for females (10mg cardarine and 10mg ostarine) so that i can take daily which i wouldve not been able to do at the usual dosage. Thank you ozsarms 💕
