I upped Legend to 8mg after a few days already and upped to 2,5 caps, 3 caps and 3,5 caps (14mg) over the month. I had a nice pump during workout but the weight gain was only 2 pounds. Strenght around 10 to 15 pounds on my 10 rep bench. After a month I stopped with the LGD and changed to Anavar for a couple of weeks to get at least the "on" feeling.
So dont expect too much of LGD especially at only 4mg or 8mg. It is very mild and a little bit more stronger than ostarine which I tried as well. The good thing is that I had zero sides.
