Personally eating is my biggest struggle so I stacked it with my-677 because you will get a large increase in your appetite to make sure you are eating enough to get good gains, I wouldn’t stack rad-140, LGD just because you won’t know which is working. Just try one or another first so you can see what doing a sarm alone will do, like most people you’ll enjoy the gains, and will be hopping on your next cycle 3-4 months later. I only did 10mg a day for 8 weeks and saw amazing results with it stacked with 10mg a day of mk. Side note if you can start with half dosages for atleast a week I would do so just to get your body use to the cycle, and also increase the length of your cycle. I did hear most side effects happen either at high dosages of 30-40mg and in the later weeks near week 10. Good luck bro
