Andarine is usually used in conjunction with other arms like above, but it can be dosed anywhere from the 50-150mg day. Dosing for bulking or recaps should be 50mg or higher, but cutting should stay at 50mg. As Andarine (s4) has a short halflife, splitting up the dose to 2 or 3x a day is optimal, to keep levels in the body high.
It can also be dosed 1 hour before a workout, only on workout days and this is called Pulsing, resulting in some slight fat loss, but decent strength gains.
S4 is usually dosed on a five day on, two days off schedule (Monday to Friday on, Weekends off) to reduce the side effects affecting eyesight.
