Bio-Gen Osta-50 contains MK-2866 sarm in a dose of 25 mg per ml. High concentration for use by advanced athletes. Ostarine, also known as Enobosarm, is a selective SARM androgen receptor modulator. The preparation stimulates steroid hormone receptors (androgen receptors) mimicking the effect of testosterone.

Ostarine in a liquid form with high bioavailability!

It is one of the most popular sarms used among professional athletes due to its extremely satisfactory effects and virtually zero side effects. MK 2866 can activate muscle stem cells (satellite cells) that help to remodel and regenerate muscles. Research shows that this ingredient stimulates cells in connective tissue that are needed for muscle regeneration after injuries.

We recommend the use of the Osta-50 supplement primarily to ensure the growth of lean muscle mass without excessive water retention, increased strength, endurance, energy increase and well-being. The supplement does not increase aggression and when using doses up to 25 mg, there is no need to use PCT supplements.

For all bodybuilders and athletes, the main problem with reduction cycles is muscle loss. An ostarine supplement addresses this problem by effectively preventing muscle breakdown while promoting fat loss.

Ostarine inhibits catabolism by stopping the body from using proteins as a fuel source. Use allows you to maintain the growth of muscle mass after the end of testosterone replacement therapy. Users who are very sensitive to estrogen or who use high doses of -35 mg / day should combine it with aromatase inhibitors that prevent the conversion of androgens to estrogen. Most ostarine cycles last between 8 and 12 weeks.

A beginner's cycle starts with a lower dose of 10 mg. With more experience with the use of sarms, the dose may be increased, but the entire cycle should not last longer than 12 weeks. Ostarine is highly anabolic, and thanks to a good calorie-surplus diet and intense workouts, you will easily develop new muscles.
