59% on average in men. But that's besides the point. If your HTPA reads lower E then it kicks in. So it stands to reason that you'd want it to kick earlier than you need it to post cycle.
Nolva is old school now. Anastrozole didn't become popular until about 5/6 years ago. It was a fairly new drug to the bodybuilding scene back when I joined elite. It had been spoken about before but I don't think it's true benefits to a bodybuilder were realised until about 2000.
It was also VERY expensive around that time until the UG labs started producing Liquidex. Liquidex is an UG product, Arimidex costs a fortune for a box of 28 but the option of cheap liquidex not being available made Nolva the more popular by far.
Now the price is so good, there is no reason to opt for second best. That's why I'll be running AG Liquidex this cycle! lol
im sorry thats just not true. not only does a-dex block aromatization it will also increase natural test levels up to 58% if taken at the 1mg per day dose
