I never got much from it but I did only use it while on TRT (200mg/wk Cyp). My wife on the other hand got very good results from it. Did a good job of holding onto mass while cutting on Clen and OTC fat burners. She also uses AAS and compared it to a low dose of Anavar (5-10mg/day). She got zilch from 12.5mg but would use 25mg again if she wasn't doing H(T)RT (recent development). I went as high as 50mg/day and did hold a fair amount of size on calorie restriction. Only caveat, again, I do run low dose Testosterone year round.
