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.
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).
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.
Ostarine shines in recomping due to its nutrient portioning results. 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.
MK-2866 can help cut whilst preserving muscle gains and decreasing calories. Suggested dosing is 12.5-15 mg for 4-6 weeks.
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.
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.
Bench Press: 245 to 295 (+60 lbs)
The pumps were great and I experienced no side effects at all.
