So, Vector would only enhance what you are doing... what are you doing? lol. MK677 is a long-term 6 months etc. and promotes healing at the least, but really Vector would add to your strength gains by a large margin; muscle mass; recomping; etc. It's a superb stand alone as well as complimentary supplement that would be amazing.
DM me if you have any further questions, and would like to use my code at BLR's site.
