Ok so I just ordered some MK 677 and MK2866 to do my first ever stack. I have 2 questions I hope y’all can assist me with as I am a rookie. 1. How will I tell if I got good stuff or not? And 2. What PCT should I run. I’m going to do an 8 to 12 week cycle depending on how it goes. Any advice to my questions would be greatly appreciated. So thank you.
