I remember reading about Halo years back, if I remember correctly it is one of THE most liver toxic and androgenic steroids available. If my memory serves me correctly and this is true then it makes
a) a poor choice for anyone who wants to use it regularly and who values their liver
b) a poor choice for any woman ho doesn't want a huge clit, back and facial hair and a deep voice.
I believe oral primobolan is the least androgenic and least (if at all) liver toxic oral steroid, meaning that hypothetically (I'm not qualified to give out steroid advice, especially to women) it would be a good choice to a woman due to the virtual absence of androgenic side effects.
HOWEVER it is heavily counterfeited, I managed to get some pharm grade (Shcering) oral primo years back in 2004 from Thailand and even that was expensive. I understand anavar is more widely available but also heavily counterfeited which can pose a serious problem to any women if it contains more androgenic compounds such as Dbol.
