MK 2866 (Ostarine)


Chemical Name: C19H14F3N3O3
Other Name(s): Ostarine, Enobosarm
Half Life: 24 hours

Ostarine, also known as MK-2866 is a SARM (selective androgen receptor module) created by GTx to avoid and treat muscle wasting. It can, later on, be a cure for avoiding atrophy (total wasting away of a body part), cachexia, sarcopenia and Hormone or Testosterone Replacement Therapy.

This type of SARM cannot only retain lean body mass but as well as increase it. Ostarine is often mistaken as S1 but S1 was created earlier and is no longer going through more expansion.

Benefits of Ostarine

MK-2866, although totally safe, can provide subtle but consistent gains in muscle, size and strength in your rodent. It’s safe to say you can easily gain 5-10 lbs of muscle over several weeks.

What’s most important is that the gains you receive are lasting and will stay with you for the most part.

Some of the other benefits include:

  • Increased lean mass gains
  • Better strength
  • More endurance
  • Joint healing abilities
  • Anabolic (even at doses as low as 3 mg)

In fact, many athletes take Ostarine for those very reasons, like Amanda Ribas UFC fighter who was tested positive for the compound in June of 2017 and suspended for two years over it.

The Science Behind Ostarine

SARMS bind to the androgen receptor (AR), which then show osteo (bone) and myo (muscular) selective anabolic activity as a result.

This tying and stimulation intensifies protein synthesis and builds muscle.

Ostarine causes muscle growth in a similar way to steroids, but without the negative effects, you would typically experience like on the prostate or other secondary sexual organs.

Benefits

MK-2866 uses its anabolic effects on muscle tissue fully so it’s not only a potential cure for muscle wasting ailments but brings incredible benefits to athletes who want to build muscle. It is also an agent to reduce degeneration during recovery times from serious surgery or similar conditions.

*Ostarine has undergone 8 scientific trials by GTx with about 600 subjects plus 3 efficiency studies. A 4-month Phase IIb medical trial including 159 patients have shown a complete boost in total lean muscle mass compared to placebo and the secondary goal of increasing muscle strength.

In terms of bodybuilding, Ostarine users have proven that MK-2866 can help improve lean muscle mass and strength levels.

Ostarine for Preventing Injuries

The effects of MK-2866 convert to anabolism in bone and skeletal muscle tissue, which means it could be used in the future for different purposes such as osteoporosis and as a simultaneous treatment with drugs that decrease bone density. So, it has great use as a compound for injury recovery, specifically bone and tendon related injuries.

Uses of MK-2866

Benefits of the well known SARM Ostarine have been documented in countless studies with effective dosages ranging from 25mg to 50mg per 24-36 hours.

There is no evidence that surpassing the 50mg dosage will provide any increases in benefits.

Even though MK2866 resembles a mild version LGD4033, it’s duration and tolerability throughout multiple studies have demonstrated safety and effectiveness for up to 6 months (24 weeks).

For Bulking

Ostarine shines best when used for gaining lean muscle (bulking) or putting on extra size. Suggested dosage is 25 mg for 4-6 weeks. PCT is not necessary. An increase of 6 lbs. of lean, keepable gains can be observed during this period.

You can take Ostarine as high as 36 mg for 8 weeks BUT only if you weigh 210 lbs. Suppression is expected in higher doses so PCT after a cycle is a must.

For Recomping

Ostarine shines in recomping due to its nutrient portioning results. A calorie is used to build muscle which helps in weight loss and enhancing muscle mass and strength. Suggested dosing is 12.5-25 mg for 4-8 weeks.

*Your diet must contain 30% of lean sources of protein to achieve the best recomp result.

For Cutting

MK-2866 can help cut whilst preserving muscle gains and decreasing calories. Suggested dosing is 12.5-15 mg for 4-6 weeks.

Timing

MK-2866 has a half-life of 24 hours. Each dose should be taken ONCE per day.

Ostarine Side Effects

MK-2866 is fully side effect free. The only threat is that it’s possible to experience some mild natural test shut down in cycles over 4 weeks, but the time between cycles are only 4 weeks.

Where to Buy MK-2866 Online

Due to the recent ban of SARMs, most of the authentic sites that distribute the products have shut down. No need to fret, there is always a silver lining:

sarms4you.com is an excellent choice, providing super-high-quality Ostarine for a great deal. sarms4you has free shipping on orders over $100 and worldwide shipping together with some other discounts. The shipments also include the US.

Current price for MK 2866 on sarms4you is $39.65 for 60 capsules.

Stacking MK 2866 (For MAX Results)

Not only is Ostarine a fantastic stand-alone SARM, but it works great in a stack with other SARMs and its effects become amplified.

Since SARMs carry very little side effects, you can safely take more than one at a time to develop true transformation of the physique.

At the moment, I recommend King and if you’re a woman you need to check out ATHENA.

Our Final Review of Ostarine

In the end, Ostarine is one SARM I really like, mostly due to how safe and subtle is is. You won’t put on 20 lbs of solid muscle like you will with other prohormones, and it’s not as anabolic as LGD 4033.

However, Ostarine is something you can stay on for long periods of time, see long-lasting benefits and permanent results, and works very quickly.

Here are some other reviews we have received from others:

I was on beast mode when I started using Ostarine. I made some awesome gains as well. There was very little suppression as well. I came across a fellow user’s review stating “…I had some fantastic gains and solid trainings as it gave me the extra strength I needed. Plus, it made my skin look clearer and even looking which is a surprising positive effect…”

I took Ostarine and ran a 6 week cycle while on a cut. At the end, I dropped 10 lbs from 191 to 181, and continued to get stronger and leaner maintaining the same weight.

Stats:

Bench Press: 245 to 295 (+60 lbs)

The pumps were great and I experienced no side effects at all.

FAQs

Because Ostarine has hardly any side effects and is very mild, you don’t need a PCT at all. Just take two weeks off of Ostarine every 8 weeks and then hop back on. Always listen to your body.

Yes. Ostarine has been shown to be beneficial to people whether you are cutting or bulking. Any weight you do put on will be muscle, and muscle will also help to increase your metabolism.

MK2866 and LGD4033 are very similar chemicals so using those two in a stack wouldn’t really be optimal. I’d suggest MK2866 with S4 for a cutting cycle or LGD4033 with MK677 for a bulking cycle. Of course if you don’t want to stack, they can both be used as a stand alone.

My first question has to be “has your lab animal had problems with hypoglycemia before?”

Secondly, studies have shown that the nature of MK2866 lowers the blood glucose level by 11% while simultaneously reducing insulin residence by 27%. Typically this shouldn’t develop into a problem, but for lab animals with prior hypoglycemic issues, this could lead to feeling light headed and fatigued. I would recommend using GW501516 and SR9009 until the condition is under control. You CAN use MK2866 in conjunction with blood sugar stabilizing medications.

    It’s for orally use only. You don’t need to stack anything with SARMs, because of the low risk of side-effects 🙂

  2. Teri says

    I am currently on ostarine and anafuse. This is my first week. I am a 61 yr old female. I Take 15 mg of ostarine with 4 anafuse pills. I have to take ostarine in 5 mg doses at a time. , otherwise I get nauseous if I don’t separate the pills but I have already felt strength an a slight increase in my muscles. I am definitely stronger. I was lifting 55 lbs on chest press an now lifting 60 lbs. I also have never lifted 30 lb dumbells til today. I really like these products an I’m looking forward to these next 6 weeks.

  3. Bazza says

    Can it be taken with testerome

    1. PanhandleOperator says

      I take .5ml of testosterone cypionate per week and just started ostarine and sr9009 yesterday. All of the literature I’ve found so far said it was safe and I expect to see huge gains. I just came off of a pro hormone cycle with an 8lb lean muscle gain.

      1. Chris Wallace says

        SR9009 isn’t liver toxic and shouldn’t cause any problems, but I hope you took some time off before starting a new test cycle.

  4. dan says

    this shit is the real deal, prohormones are done, it’s the generation of SARMS now, these are the most powerful legal muscle building supplements. and ostarine is #1

  5. Joe blow says

    After taking ostarine for 4 weeks and getting off for 2 I failed a NCAA drug test. Do not think it will not show up

    1. Chris Wallace says

      I would take a month off, there may be residual effects and testing for SARMs has become more advance over a very short time period. If you plan on taking a PCT for some of the more powerful SARMs, I would account for that too.

      1. SAMMY T says

        joe blow are you slow? You only gave yourself two weeks to get off arms before a ncaa drug test. You can drink too much caffeine in the morning and get popped by the ncaa. you should’ve given yourself atleast 6 months before taking the test in which you still probably would’ve failed because you seem incompetent and probably would’ve gotten busted for something else.

    2. Apollo says

      is that because of sports or will it show up on drug tests for work too?

      1. JustSomeKid says

        Why the fck would an employer be looking for sarms?? Haha

        1. Mossberg 619 says

          Lmfao!

  6. Ray says

    Can I use this with a Pre-workout like creatine monohydrate???

    Please let me know… I already purchased some Ostarine and want to know before I start my cycle!!!

    1. Chris Wallace says

      yes, there should be no problem with creatine or any stimulants.

  7. dale says

    Yes!! Iam taking sustanon & ostarine together & and 4 weeks in…. the results iam getting are amazing

    1. Steven says

      they could have also been amazing with just the Sust….. do some experimenting….
      best of luck!

  8. Caesar S says

    Yes good for weight lost. Great for lean/muscle gain. 4 weeks of it. Then cycle off asap. I also take milkthiysl one capsule every few days. For liver health.

  9. Caesar S says

    Hey. Yes it is. I’ve been all over the weight scale. Good for weight lost and muscle gain. After a full 2 weeks you will see a difference. My advice. Since I was 290 and in decent shape. But when I was 240 and taking pro hormone. I took this and got in shap . You will like it.

  10. Caesar S says

    Well when using pro hormones and other products like it. It is for muscle gain and weight loss.the benefits. From taking products like these is great while working out everyday. First time I took something similar i seen weight lost… muscle gain/lean . But don’t take after 4 weeks. If your a rookie to the test. The longest i have taken anything like it. Was 5 weeks .I also take milk thisel 1 cap every few days. This is my experience. I’ve been 290 pounds with 22 percent body fat. To 200.pds. I’ve used different pro hormones. And seen a crazy change in my body from head to toe. After 2 weeks you see a change. But.i also was working out at the gym for 1 hour plus.every day or at home 6 days a week. Now trying another product like this. And can wait . See what I can complete the end of my 4 weeks. I stopped working out for long time. So it will be exciting!!!

    Would love to try this. It seems too good to be true.

  14. Jay says

    did you use a PCT? and if you did what did you use?

  15. Vianey says

    I am a female trying to improve for my next bikini show. Would you recommend to take MK2866 and GW501516 together? and if so how can i take both of these?
    Thank You!

    1. Acromeglia man says

      Sure rats do best with 20mg/ml gw morning ED.
      Can run GW for up to 12 weeks!.
      Mk run no more then 6-8 weeks then pct.
      The fat will fall off if you walk or hike your rat. We found in the lab that female rats limbido went off chart on 4th week.

  16. CoreyA says

    What if I am mildy sick? Can I still take a S.a.r.m. or a pro?

    1. Acromeglia man says

      Sure. Will increase white cell count.
      Will actually help recovery. Thicker bones more red blood cells and white.

  17. Emily says

    Acne and hair loss – – any one else ? Should I stop taking them ? Is the hair loss reversible ?

  18. Dave says

    Your saying that it’s only slightly suppressive. Will normal levels of test recover naturally or is a pct needed? Heard loads of mixed opinions on this

  19. bob villa says

    it’s 50mg PER ml and there are 30 ml in the botlle, so that comes to a total of 1,500mg.

    If you want to do a 4 week cycle, that is 28 days, at 12.5 mg a day that s a total of 350mg, so you would have enough for 4 full 4 week cycles.

  20. JustSomeKid says

    I think whatever drugs you might be on now that causes grammar like that is more dangerous than sarms.

    1. SAMMY T says

      nick you sound illiterate

  21. David B Romsey says

    Your math is all wrong. The product contains 50mg of MK-2866 per milliliter . There are 30 milliliters in a single bottle or a total of 1500mgs per bottle. 1500 divided by 12.5 is 120…or 120, 12.5mg dosages. That means you can dose at 12.5mg for 120 days or roughly 4 months with a single bottle. Got it?

  22. puto says

    thuis is for ratones

  23. Falcon says

    What should be the timing of your dosage, meaning when during the day should you take it? I am under 170 lbs, 5’8

  24. Matt says

    No Andy, it’s 50mgs per ml. Each bottle contains 30ml so at 12.5mgs/day there’s 120 days supply

  25. Rose D Antico says

    I would like to know if Ostarine would be safe for vegans.

  26. Sentinel says

    If the bottle says 50mg per / ml and a bottle contains 30 ml and you need to take dose of 50 mg a day (thats a lot btw) then you have 30 servings of 1 ml out of one bottle = 30 days

    A more realistic dosage would be 25mg or 12.5 mg -> with 25 mg you would need to take 0.5 ml a day from the bottle and you would get 60 servings out of it aka 60 days (about 7-8 weeks)

    12.5 mg dosage -> you need to take 0.25 ml -> 120 servings from a 30 ml bottle

  27. Chad says

    Is there nagative effects to taking it at 18 years old?

  28. Jay says

    Anyone else feel slight chest pain when taking this ? Should I be worried ?

  29. RM says

    Have the same question.

  30. Blanca says

    Where can I buy it, please??
    Somebody could help me??

  31. Archie says

    Why some people said that they had gyno because of ostarine? How true is that? Thanks.

  32. David says

    Did you get any answer> cause I am wondering if a PCT is needed after 6 weeks Cycle..
    Thanks

  33. Yourafuck says

    Lool why this site bragging about a UFC fighter taking it and being banned from it …. Trying get promo of it much

  34. Don says

    I just finished my 3rd cycle and all I can say is “Beast Mode ” This stuff continues to deliver. Don’t stop making it!

  35. Fubar4fun says

    One month later after starting MK286 and I am a little stronger, my insulin resistance (I’m diabetic) is way down, and there is a slight increase in stamina but no weight loss. Being a sedate desk jockey working slave hours over the last 30 years has taken it’s toll. What would be good to stack where the benefits I’ve experienced are retained and there is more weight loss? I would like to retire in ten years and travel for twenty more. Got me a bucket list to do. 😉

  36. Jeni says

    I am a 47 year old female. I have been taking this for 3 weeks now, I have never in my life had acne issues. My shoulders and back have broken out pretty bad. I was shocked and upset over it.

    This is the only drawback I have had.
    I have had gains and strength has increased.
    Is this normal?
