EXACTLY!
Tadalafil suppresses the PDE5i enzyme which increases NO2...take 5mg every 12 hours and you won't believe the vascularity and pump you will acheive.
Now add in Arginine and Cituline and you got a great stack.
Tadalafil can be bought over seas for a fraction of the costs here (IM me if you need a referral).
I get like 60 10 mg pills for just about $60...that's like a buck a day.
Oh yea, you will get the additional benefit of really enhanced erections as well
BTW, Tadalafil has many other great health benefits for men...Google it and you will see.
