UK SARMs – MAINTAIN (MK-2866) otherwise known as Ostarine, has been described in studies as being an extremely close relation to the anabolic compound Dvar. It reduces body fat all the while increasing lean muscle mass.

It also has the best muscle tissue healing ability of all the SARMs. So you can workout harder and longer!

UK SARMs – MK-2866 creates an anabolic effect on muscle tissue fully so it’s not only a potential for curing muscle wasting ailments but also it has great potential for muscle building for athletes. It is also an agent to reduce degeneration during recovery times from serious surgery or similar conditions.

In terms of muscle building, UK SARMs MAINTAIN users have proven that MK-2866 can help improve lean muscle mass and strength levels and also maintain muscle mass during a cutting phase.

    Review by Christopher T. on 10 Jun 2021review stating I'm quite impressed with this. I’m quite impressed with this. Multiple positive benefits after 6 weeks. I’m going to finish the full 8 week duration and go 5 weeks without, then restart for one more cycle. Will let you know again when I have a better understanding of things. So far very happy.

    5th day of non stop solid training at this rate I might as well sleep in the gym since this supplement makes recovery so easy. I’m able to train just as hard the next day👍🏻
