Ostarin (Ostarine MK 2866) by Barbell Research 12.5mg 60 caps

Ostarin is a SARM made by Hardcore Formulations with one of the most potent and powerful SARMs, Ostarine or MK 2866.  Ostarine is the SARM that GTx came up with for the treatment and prevention of muscle atrophy. This is still under clinical trial and can turn out to be a medically prescription for Testosterone replacement therapy, sarcopenia, and atrophy. Because it’s a research chemical, it has been classified under the chemical know as SARMs or selective androgen receptor modulators.

What is Ostarin (Ostarine MK 2866)

Ostarine is an Androgen Receptor Antagonists which binds to and inhibit the activation of Androgen Receptors. The activation of androgen receptor alters gene expression and increases protein synthesis, therefore, builds muscle. Therefore, SARMs like mk 2866 Muscle work in same way as regular steroid, unlike prohormones, SARMs (as nonsteroidal agents) do not produce the effect of the growth on the prostate and other secondary sex organs. Thus, not only does it represent a potential new therapeutic option for a wide range of muscular atrophy (from age-related AIDS or related cancer) disease conditions, but also has tremendous potential for muscle building for bodybuilders, fitness, athletes and an agent to reduce atrophy during periods of serious surgery recovery or similar situations.


Development of MK-2866

This drug was developed in 2009, by the company Gtx, in an effort to fight muscle wasting diseases.

Ostarine has been evaluated in more than 7 clinical trials comprising of 600 subjects, and other important subjects.A 4-month Phase of clinical trial enrolled 159 patients with the study confirming its primary objective of an absolute total lean body mass increase and the secondary objective increase in muscle function.

MK 2866 demonstrated good results in Phase I and II clinical trials, increasing total lean muslce mass, enhancing strength and decreasing total tissue percent fat. Ostarine performs as a potent anabolic agent with minimal side effects on other organs (hair follicles, prostate) which are usually affected by the use of steroids.

Use of Ostarine MK 2866

You can buy Ostarine MK 2866 because it’s a tissue-selective androgen receptor (SARM) modulator for the treatment of conditions such as muscle wasting and osteoporosis. Only use these patent products for research purposes. ostarine mk 2866 is an orally androgen receptor modulator. Therefore, ostarine mk 2866 can be used for the treatment of conditions such as muscle wasting and osteoporosis.

Ostarin for Bulking

As ostarine mk-2866 is the most anabolic SARM available, its first use should be trying to gain lean muscle. Now, absolute weight gains will not be comparable to steroids such as Dianabol, but what you will gain will be almost exclusive to being lean mass. Most mass gained on Ostarine is maintained once the cycle is over. Doses of 25 mg 4-6 weeks are the most common protocol for these purposes. During these periods, there was about 6 kg lean gain. However, the side effects of the abundant steroids/prohormones will not be present. Like the majority of Ostarine supplies in bottles of 30ml to 25mg / ml, a dose of 17.5mg a day will give the user a 6-week cycle of a bottle, an excellent compromise between an anabolic and costly dose.

Ostarin for Cutting

Ostarine would enroll primarily in a cutting protocol for maintaining muscle mass while reducing calories. One of the most discouraging results of cutting is the loss of hard-earned muscle mass. The lowering of metabolic rate and hormone levels (T3, IGF testosterone, etc.) with lack of calories is a perfect environment for catabolic muscle tissue loss. As Ostarine has anabolic effects, the diet can reduce calories without having to worry about losing muscle strength. Ostarine has show a great result in helping with nutrient partitioning in users, which is excellent for cutting. A protocol of 12.5-15mg dosage for 4-6 weeks is good for cutting with Ostarine without experiencing any side effects or suppression.

Ostarine MK 2866 for Mass gain and fat loss

The effect of losing fat and gaining muscle at the same time is what the majority of users are looking for. Trying to realize this when you are not new to training is extremely difficult. Calories are taken from fat stores and calories are introduced into the muscle tissue.  Although Ostarine is taken orally, because it is not methylated, it is not as toxic to the liver as other oral steroids/prohormones.

Ostarine MK 2866 for Repair

The SARM Ostarine or MK 2866 can be used for concomitant treatment with drugs that reduce bone density. Therefore, it has a great application as a compound to use for the rehabilitation of wounds, especially in bone and tendon related wounds. Doses of 12.5 mg daily are recommended for these purposes and the improvement of joint movement that can be seen after only 6-8 days. The half life of MK 2866 is about 24 hours, which means each of the dose should be taken once in a day.

Advantages of Ostratine MK 2866 Compared to Steroids and Prohormones
