I think most ppl use it for their first cycle because when you're doing research for that first cycle you read as many different articles from as many different places as possible. Most of the Internet reccomends using nolva although the majority of Ef doesn't. I read hundreds of articles before first cycle and the majority told me to use nolva which I did and felt like shit.
In Australia, nolva is by far the most widely available pct drug available. But after the first use of nolva I decided to try low dose clomid based on your opinion Steve and I felt 100 times better.
Also, as for Australia, our supplement industry is terrible. Anything that works gets banned. In America you have pro hormones on the shelf. In Australia oxy elite as well as several other fat burners and t boosters are banned in pill form. Our customs is very very tight being an island nation, so it's hit or miss whether prescription stuff makes it through. But again because nolva is so widely available, and because there's so much info out there about it being used the last 50yrs or so, most ppl don't bother searching for a better pct.
