OP is either using them for a non-medical purpose (like many) - or maybe he is plotting something(lol). Either way, we already have a sh*t ton of threads on here about this - there's really no good reason to start a WHOLE NEW THREAD about this ever so common topic.
Or maybe he can't afford the nearly $40 retail per 100mg Viagra tab??? This same pill cost a high $11.00 -5 yrs ago. Doctors don't write scripts without a appt even for real proven problems, and Doctors cost money too. Health insurance, the majority doesn't cover any of the ED drugs. So a man can have a real medical need for this drug but not be able to afford the nearly $200.00 for 4 pills even if they have medical insurance.
He mentions the generic cost which is true outside of the extended patent granted to Pfizer until 2019 which was to expire in 2013. So a pill that cost under a buck in most countries cost about 40 bills for a single pill in the USA.
Still get a Doctor to write you a script because sildenafil citrate is available in the USA as a generic. It became generic last year. Have the Doctor write the script for
Sildenafil citrate 20 mg. (MUST NOT SAY VIAGRA IN THE SCRIPT). This is generic name of the drug and the drug off patent is
Pfizer's Revatio only available in 20 mg. Average cost for 100 mg (5 - 20 mg pills) at a retail pharmacy is about $6.00, compared to branded Viagra at $40.00. Some legal FDA approved pharmacies can sell you 30 pills for under $20.00
In fact many insurance companies will cover Sildenafil citrate with prior approval if your Doctor doesn't state its for ED.
