I just finished 1 bottle after using it for 6 months - no dramatic effect on my hair really - I dont think I'll bother ordering it again as Im in the UK and the shipping is pretty costly for what it is in my opinion - doesnt do any harm to try it I guess. I also used proxiphen-n which I will also discontinue once the bottle runs out and stick to a more slimmed down regimen of rev,spironolactone and tricomen.
