Ostarine (MK-2866) is a SARM developed by GTx for the prevention
and treatment of muscle
wasting. It may eventually be a medical prescription for the
prevention of cachexia, atrophy and
sarcopenia as well as for Hormone or Testosterone Replacement
Ostarine is the most powerful and anabolic selective androgen
receptor modulator (“SARM”) available
to the bodybuilding and fitness community, hands down, and without
Ostarine, also known as “MK-2866” or “Enobosarm”, was originally
developed by GTx, a global
pharmaceutical company that focuses on the development of small
molecules that selectively
modify the effects of androgen and estrogen receptors.

3. How does it work?
SARMS bind to the androgen receptor and demonstrate osteo (bone)
and myo (muscular) anabolic
Timing of Doses : MK-2866 has a half-life of 24 hours. Each dose
should be taken ONCE per day.
4. MK-2866 advantages and benefits:
HighlyAnabolic even at moderate doses
Excellent for lean mass gains
Truly shines when used for body recomposition
Helps increase endurance (aerobic or anaerobic)
Joint and Injury healing abilities
Half life of 24 hours which requires dosing only once a day
Non methylated so no negative effects on liver, blood pressure or
other internal organs
Minimal suppression and only a mini pct is required with rapid
Great sense of well being while on
Large increases in strength

6. Advantages of Ostarine when compared to steroids
It is non methylated so it is non toxic to the liver or blood
Some suppression may be present at doses of 25mg+ run for longer
than 4 weeks, however a stringent
PCT of prescription SERMs like Nolvadex or Clomid is not necessary.
High oral bioavailability without significant damage to your liver
as with oral steroids.
Great sense of well being while on, (without the aggression which
can often detrimentally impact users
No need for a long time period off between cycles; the recommended
time of period for normal steroid
cycles would be Time on + PCT, so for a typical 6 week cycle and 4
week PCT, a user would have to
wait another 10 weeks after PCT to start another cycle where SARMS
recovery requires minimal rest
Ostarine also resulted in a dose-dependent decrease in LDL and HDL
cholesterol levels, with
the average LDL/HDL ratio for all doses remaining in the low
cardiovascular risk category –
hence there is little impact on cholesterol values.
7. MK-2866 Application:
Lean muscle gains (bulking)
Ostarine is the most anabolic of any SARMS, making its first and
foremost use for wanting to gain lean muscle. The gains in total
weight will not be comparable to bulking steroids, however the
total gains will almost entirely be lean muscle.
The gains that are made on ostarine are very keepable and users
generally see an increase of up to 7 lbs. of lean body mass over
and 8 week cycle at 25mg day (diet dependent). The most common
dosage is 25 mg for 8 weeks. The side effects that one encounters
with steroid use will not be present on cycle.
Generally, with ostarine, the higher the dosage, the more
suppression. Although suppression is minimal and is nowhere
comparable to suppression that one encounters on steroids, any
cycle of ostarine over
a 4 weeks period requires a 3 week mini pct. A serm is not required
in this pct.
Losing Bodyfat (cutting)
Ostarine would primarily fit into a cutting protocol for the
maintenance of muscle mass while reducing calories. One of the most
disheartening outcomes of cutting is the loss hard earned muscle
mass. The drop in metabolic rate and hormone levels (T3, IGF,
Testosterone etc) with the lack of calories is a perfect catabolic
environment for loss of muscle tissue. As Ostarine has anabolic
effects, the dieter can cut calories without having to worry about
muscle or strength loss. Ostarine has also shown noticeable
nutrient partitioning effects among users, another reason why it
can be of great help when cutting.
A 15-20 mg dosing protocol for 6-8 weeks is good for cutting with
Ostarine without undergoing any side effects or high suppression.
However it must be stated that due to the lack of androgenicity,
muscle hardness and overall results are not as prominent as with
the SARM S-4.
Recomping is where ostarine truly shines. The recomping effect of
losing fat and gaining muscle at the same time is what the majority
of users are looking for. Trying to achieve this when you are not
absolutely new to training is extremely difficult.
Where Ostarine shines for recomping is in its nutrient partitioning
benefits. Calories are taken from fat stores and calorie intake is
fed to the muscle tissue. In fact many users report that Ostarine
at maintenance calories produces weight loss, while still getting
increases in strength and muscle mass.
One of the most important factors of recomping is time. As you are
trying to achieve multiple objectives,
it requires a longer time period to notice good recomp effects so
even when running steroids, these would have to be longer run
injectable compounds as opposed to the short used liver toxic oral
Although Ostarine is taken orally, it is not methylated and is not
toxic to the liver and does not have a negative effect on ones
blood pressure. Therefore it can be run for longer than oral
The dosing protocol of 20-25mg for 6-8 weeks will give excellent
Diet must also be optimized to where calories are just above
maintenance with at least 30% coming
from lean sources of protein to get the best recomp effect.
The effects of ostarine translate to anabolism in bone and skeletal
muscle tissue, which means it could
be used in the future for a variety of uses, such as osteoporosis
and as a concurrent treatment with
drugs that reduce bone density. Therefore it has great application
as a compound to use for
rehabilitation of injuries, in particular bone and tendon related
Doses of 12.5mg per day is recommend for such purposes and
improvement in joint movement that
can be seen after just 6-8 days.
