ive covered this a million times... you can drop whatever you want from pct... this is set up as a COMPLETE pct... let me put it to you this way... cortisol is called "the gains killer" and with good reason.. when your cortisol increases then what happens is that you are in a catabolic state which means your ability to add muscle as well as hold on to it is negated... also, on top of that, you will gain unwanted fat... in pct, cortisol spikes and sometimes in a very bad way.. GW501516 controls this and mk supports that... you also endure strength loss, and that makes pct a very difficult time mentally and physically and leads to gains lost and lost motivation and sometimes depression... mk2866 ensures none of that occurs... so that being said, do YOU THINK they can be left out? if its worth risking all of that, then yes, leave them out... if you want to avoid those problems, then i would advise running a proper pct as you were given... if you didn't need them, they wouldn't be included in the recommendation...
X 1,000 cortisol is the absolute worst.
