I have run ostarine a few times for different lengths at different dosages
1. When I frontloaded at 50mgs/day I started to see it's effects (increased pump, leaning) about 1week in. Where at running at 25mgs from start it kicked in about a week later.
2. I did not see or notice any estrogen type problems. No bloodwork to prove it but I believe i did not have an issue. Of course everyone is different.
3. The gains are lean muscle with some fat loss. Not as dry as s4 but still very lean. Could be used for either cutting or a bulk but do not expect any wetness
How long do you plan on running it and at what dosage?
