Some reports you can find about dna anabolics mk 677 contain some prohormones, and another said it was legit. First time i have had run focused nutrition mk 677 and it was legit, whit usually sides water and nitrogen retention, numbness and etc. Second time had ordered it again from different site and it was bunk. So it depends but have on mind to use cycle support and proper hidrate. Last time my liver values on ol gharine went over 100s.
