it is thought that the increase over 60 to 80mgs is not worth the trouble, as you may notice very little difference in gains if at all, but more sides.
I've run long cycles with it and found those doses good for frontload but back off to 40mg ed. Higher is no noticeable diff. strength wise, though I noticed I burned more cash.
I ONLY do 100mg/day now, no sides what so ever and it makes you as hard and strong as a rock. With var being a mild oral, 100mg/day is not really an issue and I have blood tests to back it up.
Minimal, they were all in normal range and I ran it for 10 weeks @ 100mg/day with Primo. My values are really off right now, so I am off cycle and going back to primo / var to let my values get back to normal. Var is not a big gainer now like dbol, tbol, but I love the effects and the fact that it is so mild it's perfect for cycles to prolong keeping values good.
