i used to take ganabol then fort dodge..always in conjunction with a low dose test like enanthate, or just an amp of sust...maybe it was test but i actually never experienced "eq dick" if that is the case we're talkin about..actually, my erections were very solid and i can stay hard nut after nut...it does increase red blood cells for better vascularity and blood flow, so i dont see why itd cause a negative effect..my libido is usualy real good on eq and test..slightly lowered in comparison with fina&test (but of course better fuckin gains with the latter combo)...good luck man
