Vascularity, Dry Strength Gains


As one of the hardest-hitting SARMs in terms of vascularity and lean mass gains, S-4, otherwise known as Andarine, usually gets compared in the bodybuilding world to well-known traditional steroids such as Winstrol and Anavar. Users tend to split the dosage throughout the day due to its shorter half-life.


S-4 is known to cause mild suppression for longer cycles in higher dosages. Reports also show that users may experience a yellowish tint when researching the compound. Individual results seem to vary a lot, a PCT may be needed.
