A friend of mine gave me a bottle of mk-677 .he has been using it for 8 months and has some good gains.he takes it m-f and takes the weekend off .I am in my last week of pct and ordered some ostranine to add in .I'm going to try 30 mg of each m-f for 4-5 weeks and see how I respond .
Anyone have any experience with these two sarms.
