You will look visibly leaner. I got results from Ostar1ne on a recomp, but keep in mind this is not a "bulker". You won't gain that much muscle (if you are a beginner/novice on a heavy full body routine based on compound exercises you will gain some mass), but you can lose fat for sure. Osta is even better on a cut. Watch for estrogenic effects. I'd keep some AI on hand, even if its only OTC Arimistane or something similar.
