rad-140

I'm 150 lbs. and 6 ft. tall, having a hard time gaining weight. And I'm 22 years old. I'm looking for advice on using rad 140 for bulking up. What would be a good dosage that you'd recommend I try? Do you think 20 mg a day would work well or do you think I should jump it up to 40 mg?

I am 24 years old and over six foot tall and 175 lb, I am a lien guy and I'm a lot of size that I want to put on the next few years. I also want to increase my energy and burn some fat. Would LGD4033 RAD140 And GW cardarine be a good stack for me? if no what did you recommend instead

I remember years ago using rad 140 and I got really good results and now everybody wants to use a stack always but no one wants to use it by itself. did something change in the past few years or people just trying to sell more sarms? If I were to run it by itself when I get good results at 20 mg...
