This is probably the most well-known SARM. It is best used to preserve muscle mass while in a caloric deficit. Ostarine can and will suppress your natural testosterone production in longer, higher dosed cycles, so a SERM PCT is needed. Ostarine can also cause gyno in some users, so it is recommended that you have an AI, like Exemestane, on hand.
The average cycle length is 6 to 10 weeks at a dosage range of 10mg to 25mg.
