I've heard the same thing OTG - except no less than 600mg.
After looking into primo a little more I'm finding it more and more attractive.
Here's some of what I've seen...
It's a moderately strong anabolic with very low androgenic properties... milligram for milligram, it's slightly less anabolic than deca.
It seems the people who are less enthusiastic about primo - aren't running it high enough, or long enough to really see its
full effect.
Those who LOVE IT - REALLY LOVE IT, and are running it in the area of 800mg.
It's also a very clean steroid and can be stacked with most anything... with consistent and lasting gains - along with an over all
sense of well being - which might be another reason it seems to be so popular with athletes..
Also, it's not aromatized by the body and is not measurably estrogenic.
If I'm off or missing anything aminoman - or anyone else for that matter - please chime in.[/F
