The cloudiness you mean is very mild at the best when it even occurs. I've never had lethargy, imho I've got a more constant feeling of being awake than normally. If some cloudiness or lethargy would occur it'd be very mild.
There's absolutely no worry about that.
lgd and mk are not going to cause any sort of lethargy whatsoever... 677 is the only one that carries this possibility... 2866 makes you feel extremely energetic... one of the very best for that!
If you have high quality legit sarms, then lethargy shouldn't be an issue. It becomes an issue with a lot of these companies that sell prohormones labeled as sarms, since prohormones are known to cause extreme lethargy
I've taken every sarm there is. The only lethargy was mk677, and that was for a day(2nd day actually). One day. Love the stuff, but the sides kill me and I cant take it.
I have been using MK-2866 and S4 for the past week, no lethargy or mental cloudiness. In fact I am feeling it is keeping me more alert and focused, normally I would get really slumpy in the afternoons at work (as I am up before 5 am). Since being on the sarms the only day I had that was yesterday due to a couple of late nights and not sticking to my diet plan.
