you can obtain nolva and letro legally, you just have to use them on your "rat".
legal anti-e's wont be strong enough to help with puffy nips, which is the first hint that gyno is on its way. once you have gyno, even minor, it is EXTREMELY hard (sometimes impossible) to get rid of it without surgery.
you can get your nolva and letro from A-G, the board sponsor. if you are absolutey determed not to purchase research chems (very easy, once again for your hamster or rat) then i would recommend a product containing ATD.
you can get these online as supps, or if youre lucky your local vitamin shoppe or GNC should have one of them.
novadex xt
reboundt Xt- probably the best one
