While you can cut or bulk on MK-677, I generally advise bulking with MK-677 as it definitely has a tendency to drastically increase your appetite, making it extremely hard to cut down without an appetite suppressant.
If you want to cut down and get shredded on MK-677 I highly suggest you get a potent appetite suppressant like Enhanced Athlete’s CODE RED Fat Burner as MK-677 will almost certainly increase your appetite significantly.
GW-501516 isn’t technically a SARM, but rather a SARM-like research chemical that is grouped in with SARMs. In fact, it acts on an entirely different pathway than a standard SARM. This has its perks, allowing users to get SARM-like results without the hormone suppressing side effects of the SARM. Though there haven’t been a ton of human studies in the lab, it’s been a really effective in home studies. As it is a stimulator for muscle glucose uptake, it works well in getting your muscles bulked and cut at the same time.
LGD-4033, or Ligandrol, is another great product for cutting and bulking. It’s seen as one of the safer SARMs since it has seen much more clinical study than some other SARMs out there. In recent studies, it proved to increase lean muscle, decreased fat levels, increased strength, and even helped with the user’s overall sense of well-being.
For these reasons, and for those concerned about losing bone mass, Ligandrol has proven to be something extremely useful. But bone density is just one benefit— it also defines muscle along with the best of the SARMs. Since it carries less of a risk for suppressing testosterone, it may be a better option for those with naturally dwindling testosterone levels.
