MK2866 is a great lean muscle builder with no adverse side affects. Stack with S4 for great lean, vascular results. Stack with GW501516 to retain and gain lean muscle mass whilst cutting. 30 capsules – 25mg

  • 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)
  • Joint and Injury healing abilities
  • 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.

Our SARMS powders are capsulated within Size 0 capsules.

    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.

  3. Vulkov

    Stacked with GW and had some serious endurance.

  14. Jono

    Great stuff, this SARM ensures some steady gains without the suppression of test at the end, although SARM suppression is pretty minor as it is, MK677 skips that whole period of heartache and let’s you carry on. Thank you OZSARMS 🙂

    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 ?

    Brilliant product

  64. Steven

    Great customer service

  65. Brad

    Hey guys, my main thing is trying to find the real thing. I got a healing stack, with sarms, growth hormone and TB500, I’ve been feeling good and without trying have put on muscle, I’m a martial artist so haven’t even tried to put on muscle, the body is just responding well to hard exercise, intially I felt tired then slowly picked up and after 3 weeks I feel excellent and have never been so quick, I’m 45 years old

  66. Deano

    been on it for 2 weeks, muscles feel a bit harder and any nagging muscle pain such as in my back that was ongoing for 6months + has been fixed, i wouldnt buy this for mass maybe LGD

  67. Ben

    Wow what a product. I was very surprised by the result of using lean (MK-2866). Naturally being a very lean and vascular person already without the use of performance enhancing supplements i was very surprised with the results. i managed to put on 2kg of weight whilst simultaneously slightly leaner and alot more vascular. Great product over all and very keen to try stacking it with more sarms products
