I recently used Huge.com to purchase my viagra.  Subscription service that can be turned off any time.  No prescription needed, only an online survey.  Love the convenience.  However, I have discovered both pro and cons with their pills.  Pros:  I no longer suffer any side effects.  I used to have really bad side effects (flushing, sinus congestion, indigestion) with pfizer pills.  Now there’s none at all.  The cons:  the expecting medicinal effect is much lower and harder to control.  I used to take A pill 1hr before appointment and that worked out well.  Now I can’t get the timing right.  I try 1hr, 2hr, 3hr before appointment and it’s a hit or miss.  Sometimes it worked for that appointment, some other times I would have a hard on 3-4 hours past the appointment time.  The erection is also not as hard as before

I've been taking Cialis for years for ED.  Not only works for me for ED but as my urologist said, "It's a Two Fer"....I usually just stay with the 5mg dose and will double down on days when I might need a "little more LIFT"....NO SIDE EFFECTS AT ALL for me...I haven't used Viagra in many years.  Stuff is old technology bro....go with the BIG C!!!

If you get a change of reaction to a different seller of pills, they might be fakes.

There are sites now that offer generic Cialis....actually, the active ingredient in Cialis. Only slightly more expensive than sildenafil (generic Viagra) and supposedly very effective, However, it's not recommended first time users like myself, so I put in my first order for sildenafil yesterday.

Actually sounds like poor quality generics manufactured who knows where. Huge.com may not use reputable over-seas manufactors. Best to stick with a known and well established on-line pharmacy.

I agree that it's prudent to sample all PDE5 inhibitors to determine which one and at which strength works best for you. Nevertheless the purity of the medication is critical. If purchasing a generic version only use a well-known, reputable brick and mortar or online pharmacy. Otherwise you may be purchasing inferior quality medication that will perform inconsistently if at all.

Don’t buy online overseas bull crap. Take your prescription to Sam’s club and get a Plus membership to save on prescription prices. Sam’s Pharmacy has Tadalafil and Sildenafil for bargain basement prices.  Just ask your Doctor to escribe it for Christ’s sakes

...everyone is different and all will not react the same. Cialis at 20 mg did not work consistently for me and the side effects were considerable. I use sildenifil 20 mg. I pay about $15 for 30 pills. I pay out of pocket.
