I just assumed GNC, meant OTC. My bad.
I know joe d says the OTC worked for him, I just don't see how. You never know with stuff like this. Many ailments cure themselves. I'll give you the benefit of the doubt joe. Perhaps they do have some weak anti e qualities, but I'd still go with either real drugs or safe natural supps. Prohormones are the worst of both worlds.
Brocolli has DIM which is a phytoestrogen and MAY compete with estrogen receptors...OR...it may just add more estrogens. I don;t like it.
I personally alternate between san and dex used concurrently with the natty anti e's in POST CYCLE.
