Viagra. If caffeine acts as a PD inhibitor, it'd make sildenafil or tadalafil more powerful, wouldn't it?
After all, they're PD5 inhibitors...
Perhaps I'm wrong and my joke was stoopid lol
I was thinking the matrix lmao.. Red pill vs blue pill?
But I dunno. Idk how Viagra works, never looked into it. I suppose they could stack but I doubt it'd a synergy or potentiation
