I might also add to Stevewxly's report...
[quote=stevewxly]i have brought quite a few. say 25-40 of these viagra pills back with me on the flight from cr to the usa, and have never been asked about them or had any problems with customs on them. although rush limbaugh the tv personality did get caught entering the country (us) with some of them. and he got busted for it. but in general i do not think you should have any problem bringing some of them back with you to the us. worst case scenario would be that they would perhaps confirep001e them at customs, but i doubt that you would face any criminal charges for that. but again i am not advising you to do that. you will be on your own with that- should you get caught.[/quote]that, anyone who thinks that they will be leaving costa rica with any of the "perfomance enhancers"(pe) might consider buying cheap "dollar store", otc(weight loss, vitamins, etc.) pills and bringing them to costa rica and replacing the original pills with pes for the trip home!
i bought a quantity of kamagra (an indian-manufactured viagra "knock-off") in thailand and the pharmacy clerk advised me to do this as a precaution!
