Indian viagara is the brand called Kamagra, and is just as good as viagra as far as I can tell. I brought my own, so I don't know the prices in Patong, but can be bought very cheap over the internet, about $2.00 US per tab.
I bought Cialis in Patong. Haven't heard about any Thai copy there. Asking price for Cialis was 2200-2400, but I would always refuse to pay more than 2000. At the pharmacy just off Rat-U-Thit next to seafood restaurants next to Tiger, he will sell for 2000 Baht.
The viagra gel, which is actually Kamagra, at least what they are selling in Patong is, is very good stuff. Half a packet sets me up fine and the side effects are much milder than the tabs, and it takes effect instantly. At the same pharmacy mentioned above the guy asks 200 per packet, but I told him I only pay 150 and he said, "OK. How many do you want?" I do think it is better than tabs if you want Viagara.
To me with Vit V, it seems to produce harder wood, but slightly less sensation. I still could usually come with it if not too tired out or having too much sex. Most days I could come three times. But when I kept that up day after day, with only 3 or 4 hours sleep each night, then it got to be a problem with being able to come. If I got 8 hours sleep, then I would be OK again, but that never happened. Actually even 5 hours sound sleep was good enough.
The last two days I was there, I actually used Vit V and Vit C at the same time. I was a little concerned that there might be some toxic interaction that would kill me, make me sick, or make my d*ck shrivel up, but that never happened. Why I doubled up was because I was getting so little sleep that I started taking valiums just to get any sleep at all, and the valiums unquestionably shortened the expiration time for the effect of the cialis. I was previously getting a full 36 hours of use out of the cialis, but after I started popping 10 mg of valium once a day, that cut the effect of the cialis probably in half, like maybe 18 hours. I could have increased the dosage of the cialis(I was doing 10 mg), but I had not anticipated the problem, plus it would get a little pricey to do so. Supplementing it with a taste of Kamagra gel worked just fine, and it didn't kill me, actually I didn't notice any bad effect from it. But if you try it and it kills you, don't send your ghost after me, please!
And for you younger guys, with the ejaculation problem caused by condoms, take it from an older pro, go get some Trojan Supra or Durex Avanti condoms and you won't suffer from that problem. They make all the difference! Pricey, but worth it and they are said to be as effective against HIV. They break a little easier than normal condoms, but if you withdraw and rewrap when there is a breakage, the additional risk is pretty negligible IMHO. When you compare the benefits of being able to come much easier compared to the small added risk, I think that it is worth it. Really, those condoms feel damn near the same as wearing no condom at all, and I don't have any stock in the company that makes them.
