Stacking ED Medicines?

Hi everyone,

I am wondering if anyone has stacked any of the three ed medicines together at once. I have seen some research chemical sites selling combos, like a viagra cialis combo (50mg sildenafil and 25mg tadalafil per ml) and I also say a viagra cialis levitra combo (50mg sildenafil, 25mg tadalafil, 10mg vardenafil per ml). DO you think these are safe?

thanks everyone

I have experience w/the c/v combo. I like it alot due to the fact that you get the quickest results from the v but then you get the sustained results from c. I've used it on several occasions w/no sides. Hope this helps.
