Id say run it at 60mgs minimum if you want good gains, 80-100mg a day for it to really shine. I have run it at 60mgs before with decent results, however I DID wish I ran it at a higher dose.
100MG ED IS THE MOST. I will be the first to throw this out there that its a shit drug.
Leave it to the Female Figure world to take Var... Imho the benefits do not even come close to justifying the cost, even if you get 10mg tabs for .30 cents each.
