Thanks for the reference. I agree about the estrogen boost to the immune system but again until this post with the reference to tamoxifen it is interesting.....if the compound is in fact lowering estrogen that would seem to be more of an AI mechanism....but if there is something inherant in blocking estrogen (as tamoxifen does) that lowers immune function then that is new to me. I dont doubt it and I will read the link, I am just saying it will be new info to me.http://www.elitefitness.com/forum/bodybuilding-supplements/bulbine-natalensis-faq-frequently-asked-questions-phytoserm-347-a-727955.html
prob find some interesting things in this thread bro.
As for its mechanism of action Nothing has been confirmed as to weather it is Ai or serm like. But taking into consideration your findings ( through your own testing) that phytoserm-347 lowered your neutrophils. Then its actions might be closer to Tamoxifen based off the fact that through testing it has been shown to do the same http://www.ncbi.nlm.nih.gov/pubmed/15696052
But again nothing has been set in stone ether way.
