i don't doubt it but i don't do meth and i quit phenibut because i found i was leaning towards a habit during covid lockdown. as for viagra, i took half a pill twice and was crazy hard for hours, down to a semi during rest breaks but never soft the whole night and rock hard again as soon as i got back into it. but i don't have easy access to it, and prefer the other effects of the herbal stack.
