Most sarms if not all and especially RAD 140 could take between 6-8weeks for measurable and visual results to come. Also, note that, the same RAD 140 is in the market with 5mg, 10mg, 15mg etc,

It tells you that, sarms with 15mg or more are stronger than those with 10mg or 5mg. This is true because RAD140 is one of the most widely used SARMS.
