SARM stands for "Selective Androgen Receptor Modulator". They are a class of hormones that serve as ligands that bind to cellular androgen receptors. SARM compounds offer the benefits of traditional Anabolic Androgenic Steroids (AAS) with a much lower tendency to produce unwanted side effects that are most common with ASS. SARMs can increase skeletal muscle mass and boost strength in androgen-defiecient individuals.

Ostarine MK-2866

Ostarine is an orally active nonsteroidal SARM developed by GTx, Inc. A 12-week double-blind, placebo-controlled phase II clinical trial on 120 healthy elderly men (60+ years old) and postmenopausal women showed that Ostarine significantly increased lean body mass, improved physical function, and improved/increased insulin sensitivity.

Users typically take Ostarine during recomposition phases. During these phases some users report 7lb increases in lean body mass in just 8 weeks and users report decreased fat mass and slight increases in muscle and strength.

A compound that offers both fat loss, muscle gain, and strength gain benefits sounds extremely appealing to athletes looking to take their performance to the next-level. 

What to Expect & Side Effects

Gains of 5-10 lbs of bodyweight are typical results are gains of 10 pounds for a 4-8 week cycle. These increases happen while eating higher calorie diets & a higher protein diet.

Anecdotal evidence shows that human use of MK-2866 will result in reduction of natural testosterone production. Therefore anyone who undergoes research with Ostarine should look into PCT Post Cycle Therapy to regenerate natural testosterone production and prevent a hormonal rebound of hormones such as estrogen.

There have been no reported estrogenic system changes after taking MK-2866. A miniature Post Cycle Therapy as stated earlier is advised - (Blackstone Labs PCTV or Repp Sports PCT) in order to reboot the natural testosterone production in your body after the cycle is finished. PCT should be taken for 4-6 weeks.

Ostarine can be safely used by women.  The dose usually ranges from 10-15mg daily.  Women respond even better than men to Ostarine.  They often see noticeable reduction in body fat + gains in lean muscle.

Finally, Ostarine isn’t associated with liver toxicity: so you’re not doing long-term damage to your own body’s organs. Also, SARMS have no effect on blood pressure levels.

Who can take Ostarine & Doses

Ostarine has been dosed at 10-30 mg per day, taken orally, once a day in the morning. While being ran 6-12 weeks, with 12 weeks giving the best results.

Not recommended for anyone under 21 years of age.

  • I bought lean mass extreme at a local shop. Was shocked at my strength and energy after only 3-4 days. I’m looking for a more affordable resource. How much do you charge including shipping?
