What is Ostarine MK2866?

Ostarine was the name given to the compound MK-2866. This is a Selective Androgen Recepector Inhibitor, otherwise known as a SARM.

Pharmaceutical research and development company GTx were primary developers of this compound, and it’s intention was to treat or manage diseases such as Muscular Dystrophy (MS), HIV/AIDS and potentially be used in the treatment of Sarcopenia.

Researchers also believed that Ostarine MK-2866 could be used to Testosterone Replacement Therapy.

SARMS are a group of compounds which act upon androgen receptors within the body to cause anabolic effects, similar to Selective Estrogen Receptor Modulators (SERMS) such as Tamoxifen which is used primarily in the treatment of breast cancer.

Ostarine MK2866 and it's use in Bodybuilding

In recent years Ostarine has become popular with bodybuilders, and has been cited as a alternative to Anabolic Steroids.

The primary reason for this, is the fact that that Ostarine MK2866 has a potent anabolic effect, while having a very low androgenic effect. This allows users to experience less androgenic side effects while using these compounds.

Some androgenic activity may still exist, however, anecdotally, most users report very little if any androgenic side effects.

Anabolism and Ostarine (MK2866)

In comparison to AAS, many consider Ostarine to be similar to the effects of Oxyandralone (Anavar). The primary characteristics of Anavar include lean muscle gain, no aromatisation (conversion to oestrogen), muscle hardening and reasonable lean muscle gain.

This makes Ostarine very desirable for those looking to gain and lean muscular physique without the Oedema caused by steroids such as Testosterone and Nandralone.

Lean body mass gains are considered to be easier to maintain then AAS, owing to the fact that HPTA recovery is easier for most.

Ostarine is being used to replace oral steroids in many users cycles because of the reduction in side effects. Oral steroids such as Turinabol and Oxymetholone often have harsh side effects, which can effect a user’s quality of life. These can include lethargy, appetite loss, and liver stress.

Ostarine is used to achieve a hard, dry look. Dorian Yates is a prime example of this look

Ostarine SARM and Fat Loss

Bodybuilders will often employ drugs with hardening type effects during cutting cycles, to emphasise the lean and dry look they seek.

Ostarine is a prime candidate for this use, owing to it’s lack of Aromatisation and hardening effects on the muscle. Many users are replacing “old school” AAS with SARMS such as Ostarine because of the lack of side effects, while still obtaining the desired effects on their body.

Both SARMS and AAS have a small effect directly on fat loss. Many studies have found that men with higher levels of AAS generally have leaner body compositions.

HPTA Supression and Female use of the SARM Ostarine MK2866

All SARMS are capable of causing suppressing the HPTA, but to a much lesser degree then hormones such as Testosterone and Trenbolone. Many users note that recovery from a Ostarine or other SARM cycle is much easier than recovering from the use of AAS. Post Cycle Therapy should be considered but not always necessary.

This compound has been citied as being a very effective SARM and Performance Enhancing drug for female athletes, because of the rarity of androgenic side effects. This side effects can include changes in facial shape, hair growth and voice deeping.

Many users report that these effects are not common in Ostarine use, making it a highly effective option for female users who are concerned about the effects of androgens causing unwanted effects.

Using anabolic steroids as a women is very complex, much lower doses are required due to the females body being extremely sensitive to anabolic and androgenic hormones.

Side of effects of using Anabolic Steroids as a female can be physically and psychologically debilitating. This makes Ostarine a viable option for female athletes looking to gain an advantage in performance.

The most common side effects of Ostarine in women is temporary menstrual cycle interruption.

Ostarine SARM MK2866 Conclusions

Ostarine, while new to the performance enhancing world, has already gained incredible popularity within the bodybuilding industry. It is being positively cited as an alternative to AAS, owing to it’s legality, lack of side effects and powerful effects.

Although SARMS are still unknown to many, the anecdotal and scientific data that is available so far is promising, with many previous AAS users now only using SARMS.
